Product Description

Introduction

At Seawoo, we offer a wide range of roll chocks tailored to meet the specific requirements of various rolling mill types, including:

• Work Roll Chocks: Designed to support the smaller working rolls, these chocks are built to handle the high pressures and temperatures involved in the rolling process. They are essential for achieving the desired material thickness and surface finish.

• Backup Roll Chocks: Supporting the larger backup rolls, these chocks are crucial for maintaining the integrity of the rolling mill structure. Our backup roll chocks are engineered to withstand heavy loads and provide long - lasting support to the rolling operation.

• Intermediate Roll Chocks: Used in multi - roll mills, these chocks provide support between the work rolls and backup rolls, helping to distribute the rolling forces evenly and prevent deflection.
 

Advantages

• Precision Engineering: Our backup roll chocks are manufactured with the highest standards of precision to ensure perfect alignment and optimal performance.   

• Durability and Reliability: Our backup roll chocks are designed to endure the harsh conditions of rolling mills, offering exceptional durability and reliability. Our backup roll chocks are built to minimize downtime and extend the service life of your rolling mill components.

• Customization: We understand that every rolling mill has unique requirements. That's why we offer custom - designed chocks tailored to fit your specific operational needs. Whether you need chocks for a new installation or a retrofit, our team can provide a solution that meets your exact specifications.

Technical Support

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
