AI Technical Summary

Technical Problem

Under high-temperature thermal relaxation cycles, the stress in the ladle slide plate cannot be released, making it prone to cracking and deformation, which affects the safety and continuity of molten steel casting.

Method used

Design a steel-clad skateboard, including a skateboard base, a working layer, a buffer layer and a supporting shell. The buffer layer consists of an elastic layer and a rigid layer with inclined contact surfaces. The buffer gap is filled with buffer strips. Thermal expansion stress is released by the sliding of the inclined contact surfaces. Graphite lubricant is used during the manufacturing process to reduce friction.

Benefits of technology

This improves the structural stability and thermal deformation resistance of the steel ladle slide plate, prevents cracking and interlayer delamination, ensures that the slide plate remains intact and reliable under repeated high-temperature and low-temperature shocks, and improves the manufacturing quality and production stability.
