The rolling mill work roll chock made by CHAENG (Great Wall Steel Casting) is mainly made of cast steel. After heat treatment, it has good wear resistance and high strength. Since the work roll chock is the main force-bearing member in the whole equipment operation, it also requires a certain shock absorption performance. So when CHAENG manufactures the chock, each step is complicated and very strict from casting materials to heat treatment.

According to the customer's drawings, CHAENG analyzes the processing requirements of the work roll chock and formulates a series of rigorous manufacturing processes to provide customers with a well-suited rolling mill work roll chock. 

Process advantages of CHAENG work roll bearing chock:

Base on the requirements of customers, CHAENG selects appropriate wooden mold for modeling design, and uses CAE software to simulate the casting process. Strictly according to the process procedures to produce high-quality work roll chock: wood mold - modelling - pouring - heat preservation - out of the pit, sand cleaning - heat treatment - roughing, finishing - packing and delivery.

1. Software simulation

Using CAE software to digitally simulate the casting process, predict product defects and other issues, so as to develop technical solutions in advance and avoid casting defects, which is a new realm of large-scale sand casting technology.

2. Wood mold modeling

Control the mold and molding process with instruments such as infrared range finder, coordinate measuring machine and endoscope.

3. Molten steel casting

The company has two 60-ton alkaline arc furnaces, and also introduced German OBLF GS1000 vacuum direct reading spectrometer, carbon-sulfur high-speed analyzer, and microcomputer three-element high-speed analyzer to carry out refined inspection of molten steel components.

4. Out of the pit, cleaning the sand

The latest introduction of a large-scale trolley-type automatic shot blasting machine can clean the castings faster and more efficiently.

5. Heat treatment

Our company has 4 large-scale natural gas heat treatment furnaces, the largest of which is 6*6*16.5 meters, which can meet the heat treatment requirements of different sizes of products.

6. Machining

A machining (group) center, 8 sets of various submerged arc welding machines; 6 sets of various quenching and electric furnaces; 22 sets of lifting equipment, leading equipment, high degree of intelligence, maximum lifting capacity 200T, meeting the Great Wall casting The need for steel to produce finished products.

7. Quality control

CHAENG has the advanced casting equipment, strictly follows the national lever-2 detection standards, and executes 360° all-round nondestructive testing system, to ensure the reliable quality and long service life of steel castings

The work roll chock, like the bearing, must be regularly maintained to detect problems early, so as to improve productivity and service life. CHAENG can produce large work roll chock according to your drawings, contact us!
