Organization Profile

Haian CZPT Casting Co.,Ltd. is recognized in 2003 in CZPT Town.

In 2007,we moved our manufacturing unit to Sunzhuang town and now we can supply bigger metal castings with max. weight forty five tons.

In 2011,we created a new sand mold maiking workshop with one hundred twenty tons refinining CZPT and the max. bodyweight can be a hundred and twenty tons.

In 2013,we compensated more attenion on the castings for shipbuilding and started to source maritime castings for most of domestic well-known shipyards.

From 2013 to 2571,we purchased more and much more machines to bolster our capability from rough machining to concluded machining.

In 2571,we constructed an additional new sand mildew creating workshop for the swift development of marketplace need.

Now we month-to-month supply 6000 tons diverse castings for different buyers of distinct sector,this kind of as cement mill,shipubuilding,petroleum machinery,rolling mill,forging press and so on.

 

Prdocution Process

one)Sample producing

We have our very own wooden sample making workshop.
But our business is often busy,
we also have all around ten sub-contractors for sample making.
They help us for the sample but will be inspected according to our policies.
We will report for every single pattern inspection.

2)Sand core producing

We have all around 80 technicans for sand core creating which is divided into close to ten teams.
Most of the technicans has much more than ten years’ knowledge.

Most of the sand core is manufactured by silica sand with typical sand inside of it.
The common sand will be utilised repeatly.
For some crucial situation,such as R corner,we will use chorme ore sand.

The outdoors of the sand main,we will do the painting,burn and thoroughly clean it.

We will assemble diffrent sand cores collectively and wait for pouring.

3)Melting and pouring

We usually do the melting right after mid-night for less expensive electric charge.
And we generally do pouring in the early early morning.

No. Gear Name Amount(Established)
1 25 tons Electrical Arc Furnace one
2 50 tons Intermediate Frequency Furnace 2
3 one hundred twenty tons Refining Furnace 1
four one hundred twenty tons VD Furnace 2

four)Cooling
Chemical composition

When we do the pouring,we will also just take the sample and check the chemical compositon.

Right after pouring,we will hold out for diverse time for cooling in accordance to casting’s fat.

Product Fat in blank(Metric Tons) Cooling Time(Hour)
1 <25 forty eight
2 >25-forty 72
3 >40-55 ninety six
four >55-72 120
5 >72-96 one hundred forty four
six >96-a hundred and fifteen 168
seven >115 192

5)Warmth treatment

The optimum dimensions of the warmth treatment CZPT is 12m*9m*6m.
The dimensions also make a decision the max. measurement we can make for the casting.

We only can do normalizing and tempering.
The quenching CZPT will be accomplished by our sub-contactor.

Reducing the riser,we pick thermal reducing approach.

Following warmth treatment,we will do the mechanical home check.

six)Draw the line and do the initial tough machining
We can do the machining from rough to completed machining.

seven)NDT right after rough machining
 

8)Welding fix
We have prosperous encounter for making assistance rollers and kiln tyres,
then there is no welding for the outdoors functioning position.
This is our specific technology.

Every single yr we offer around 400pcs kiln tyres,930pcs assist roller,a hundred and seventy sets gear( in 2 halves).

But for some other castings,if we do the welding fix,
we will do the tempering for pressure aid later on.

All of our welders have the SGS certficate.
 

9)Closing machining
We have a whole lot of vertical lathes from 2.5m to 10m.
 

 

Certifications

We get acceptance from CNAS for our laboratory.
We also have 9 class certification,these kinds of as Abs,DNV,NK,RINA,KR,CCS,BV and so on.
 

Packaging & Transport

We source a good deal of castings for cement mill,rolling mill,shipbuilding and so on.

We can do the packing according to our principles or according to customers’ prerequisite.

 

 

Soon after Revenue Service

Usually there is a twelve months good quality warantty.

We do at minimum 3 instances NDT:right after rough,semi-completed and finished machining.

And also the client will do the witness throughout or soon after completed machining.

If there is also any difficulty when you receive the castings,
remember to ship us images and detailed defects,
we will negotiate with you and make a payment.

A third social gathering inspection just before shipment is welcomed.

The benefits of using pulleys

A pulley is a mechanical device that converts force into rotation. There are many advantages to using pulleys. Let’s take a look at a few of them. This article will describe the advantages, types, applications, and power sources of pulleys. You can then choose the pulley that best suits your specific needs. If you’re looking for a new tool to help you with a certain task, this article is for you.

Mechanical advantage

The mechanical advantage of a pulley can be defined as the ratio of applied force to the applied force. The mechanical advantage of a pulley can be calculated by considering several factors, including weight and friction. It can be calculated by the force applied per unit length of rope and the number of pulleys used. In a single-circuit system, the force required to lift a heavy object is equal to the user’s body weight.
The mechanical advantage of a pulley can be realized by comparing it to a seesaw. Both uses of rope are suitable for lifting objects. A rope four times heavier than a kilo is four times as effective. Because the forces on both sides of the pulley are equal, a small force is enough to move a large weight a short distance. The same force can be applied to a large mass to lift it several meters.
After introducing the concept of mechanical advantage, learners will practice using the pulley system. In addition to testing the pulley system, they should also calculate its mechanical advantage. Using either the instructor-provided handout or the learner’s workbook, students will determine how easily the pulley system functions. Once they have completed the test, they can discuss their results and how the system can be improved. These courses are best completed as part of a mini-unit or as a standalone main course.
The mechanical advantage of the pulley system is proportional to the number of rope loops. This circuit requires the same force as the dual circuit to lift heavy objects. A single lap requires only a third of the force to lift a double lap, while three laps require almost half the energy required for a single lap. The mechanical advantage of the pulley system becomes constant as the number of cycles increases.
The 3:1 Mechanical Advantage system feels like lifting a 300-pound load with three feet of rope. The three-foot-long rope moves the load one foot high. Understanding the mechanical advantages of pulleys is critical for rescuers when trying to create the perfect pulley system. Ideally, the pulley system will be anchored to a nearby rock, tree, pole or person – if the weight is not too heavy.

Types of pulleys

There are several types of pulleys. V-belt pulleys are the type commonly used in vehicles and electric motors. “V” pulleys require a “V” belt, and some even have multiple V grooves. “V” pulleys are often used in heavy duty applications for power transmission because they reduce the risk of power slippage.
Composite pulleys combine the properties of fixed and movable pulleys. Compound pulleys are able to change the direction of force while requiring relatively low force to move even the heaviest loads. Mechanical advantage is a measure of the effectiveness of a machine or equipment. It can be divided into three categories: force, distance and mechanics. Once you understand how each type works, you can design complex machines.
Fixed pulleys: These pulleys are the most basic type of pulleys. They use ropes and slotted wheels to move with the lifted object. Because they are so simple to set up, lifting heavy objects is a breeze. Although the moving object feels light, it is actually heavier than it actually is. These pulleys are used in construction cranes, utility elevators and many different industries.
Compound Pulley System: A pulley pulley is a combination of two fixed pulleys and one movable pulley. Compound pulley systems are effective for moving heavy objects because they have the largest force multipliers and are flexible enough to change the direction of the force as needed. Composite pulley systems are commonly used in rock climbing, theater curtains and sailing. If you’re looking for a pulley system, you can start by evaluating the types of pulleys and their uses.
Construction Pulleys: These are the most basic types of pulleys and have wheel rails. These pulleys can be lifted to great heights and attached to chains or ropes. They allow workers to access equipment or materials from greater heights. They are usually mounted on wheels with axles and secured with ropes. They are essential tools for construction workers. There are many different types of pulleys out there.

energy source

Belts and pulleys are mechanical devices used to transmit energy and rotational motion. The belt is connected to the rotating part of the energy source, and the pulley is mounted on the other. One pulley transmits power to the other, while the other changes the direction of the force. Many devices use this combination, including automobiles, stationary generators, and winches. It is used in many home applications, from conveyors to treadmills. Pulleys are also used for curtains in theater halls.
Pulley systems are an essential part of modern industry and everyday life. Pulleys are used in elevators, construction sites and fitness equipment. They are also used in belt-driven generators as backup power. Despite their simple and seemingly humble beginnings, they have become a versatile tool. From lifting heavy objects to guiding wind turbines, pulley systems are widely used in our daily lives.
The main reason why pulleys are so popular is the mechanical advantage they offer. They can lift a lot of weight by applying very little force over longer distances. For example, a small motor can pull 10 meters of cable, while a large motor can pull 1 meter. Also, the work done is equal to the force times the distance traveled, so the energy delivered to the large motor is the same.
The power source for the pulley system can be cables, belts or ropes. The drive element in a pulley system is usually a rope or cable. A belt is a loop of flexible material that transmits motion from one pulley to another. The belt is attached to the shaft and a groove is cut in the pulley. The belt then transfers energy from one pulley to the other through the system.

application

A pulley is a mechanical device used to lift heavy objects. They reduce the amount of work required to lift heavy objects and are an excellent choice for many applications. There are several different applications for pulleys, including elevators, grinders, planters, ladder extensions, and mountaineering or rock climbing. Let’s take a look at some of the most popular uses for pulleys in modern society. These include:-
A pulley is a mechanical device that changes force. To use, you wrap the rope around it and pull down to lift the object. While this device is very useful, a major limitation of using pulleys is that you still have to apply the same force to lift the object as you would without the pulleys. This is why people use pulleys to move large objects like furniture and cars.
In addition to lifting heavy objects, pulleys are used in elevators, flagpoles and wells. These systems allow people to move heavy objects without straining their backs. Many other examples of pulleys in the home include garage doors, flagpoles, and elevators. They also help raise and lower flagpoles, which can reach several stories high.
There are two basic types of pulleys: movable and fixed. Fixed pulleys are attached to a ceiling or other object using two ropes. Modern elevators and construction cranes use movable pulleys, as do some weight machines in gyms. Composite pulleys combine movable and fixed pulleys to minimize the force required to move heavy objects.
Another type of fixed pulley is the flagpole. A flagpole can support a country, organization, or anything else that needs to be lifted. A taller flagpole creates a prouder moment for those who support it. The operation of the rope and pulley mechanism is very simple. The user simply attaches the flag to the rope, pulls the pulley, and he or she can watch the flag rise and unfold.
