OEM Large Size Cast Roll Chock for Rolling Mill is a critical component in the manufacturing process of rolling mills, designed to support and house the rolls, ensuring accurate and stable rolling of metals like stainless steel, aluminum, and bronze
Here's an overview of the key features and advantages of OEM Large Size Cast Roll Chock for Rolling Mill:
Design Compatibility:
Company Profile
These chocks are designed to be compatible with various rolling mill machinery, allowing for precise rolling operations
High Load-Capacity Roller Bearings:
They are engineered to bear the heavy loads exerted during the rolling process, with roller bearings that can withstand the immense pressure
Performance:
Offering high performance, these chocks ensure the efficient operation of the rolling mill, contributing to the production of high-quality metal products
Easy Installation:
They are designed for ease of installation, which reduces downtime and facilitates maintenance
Packaging and Shipping:
Providers offer professional packaging services to ensure the safety of the goods during transit, with fast delivery times and one-stop service
Quality Control:
The entire process from raw material to delivery is under strict quality control, including chemical composition, mechanical properties, dimensional inspection, ultrasonic testing (UT), magnetic particle inspection (MT), and penetrant flaw detection (PT)
Customization (OEM):
Manufacturers welcome OEM orders, providing technical support with professional personnel to meet specific customer requirements
Material and Chemical Composition:
The roll chocks are made from materials like ZG25CrNiMo, ZG30CrMo, and ZG35CrMo, with specific chemical compositions that ensure their durability and reliability
Mechanical Properties:
They possess yield strength, tensile strength, elongation, and reduction of area properties that meet international standards, ensuring their mechanical reliability under heavy loads
Support and Alignment:
|
Support and Alignment:
- Chocks, also known as roll housings, are essential components that support the work rolls and backup rolls in a rolling mill. They ensure the correct vertical and horizontal positioning of the rolls, which is vital for the precision and quality of the rolled product
|
|
Load Distribution:
- Chocks bear the forces exerted by the rolls during the rolling process. They are designed to handle the high pressures and stresses generated, ensuring that these forces are transferred safely to the mill structure
|
|
Maintenance and Repair:
- Regular inspection and maintenance of chocks are necessary to prevent failures that could lead to significant financial losses. Chocks are carefully disassembled, cleaned, and inspected for damage. Advanced inspection technologies are used to assess critical dimensions, and repairs are planned in the most cost-effective manner possible
|
|
Material and Manufacturing:
- Original chocks are typically manufactured from cast steel or gray cast iron, with carbon content ranging from 0.2% to 0.3%. Minor welding repairs are possible for cast iron chocks, but major repairs are not feasible due to the extensive welding material required
|
|
Stress Analysis and Optimization:
- Finite Element Analysis (FEA) is used to analyze the stress distribution within chocks, which helps in optimizing their design for improved service life and load-bearing capacity. Studies have shown that chocks made from certain materials, such as CA6NM, can produce significantly less deformation and equivalent stress compared to those made from gray cast iron
|
|
Roll Load Calculation:
- The roll load, which is the force applied by the rolls, can be calculated using established theories like the T-selikov theory. This calculation is essential for determining the strength requirements of the chock and ensuring its ability to handle the forces exerted during rolling
