Introduction
Bearing housings are critical components used in rolling mills, providing stable housing for the bearings that support the rolls during the metal rolling process. These bearing housings are designed to withstand the intense forces involved in rolling operations, ensuring the rolls remain properly aligned and can move smoothly under the heavy loads. The reliability and durability of cbearing housings are vital for maintaining product quality and operational efficiency in steel and aluminum rolling mills.
Advantages
1. Seawoo bearing housing uses high-quality steel ZG35, ZG45, with high hardness, strong wear resistance, high load-bearing, long continuous work, good stability, and long service life.
2. Seawoo bearing housing sets the oil level observation scale, which make the staff be able to observe the oil level situation, timely replenish oil, to prevent accident damage caused by lack of oil lubrication.
3. Seawoo bearing housing takes use of thin oil lubricant to minimize the friction coefficient of bearings. So the energy-saving effect is good, the working temperature is much lower than the dry oil and extend the bearing service life.
4. The fabrication route is governed by the provisions of the implemented Quality System ISO 9001:2015.

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
