AI Technical Summary

Technical Problem

Existing technologies present challenges in the installation of water beams for walking beam furnaces, including high installation difficulty, high cost, high safety risks, and difficulty in precision control. In particular, it is difficult to achieve efficient and high-quality installation in high-temperature environments.

Method used

A cold-installation method is adopted. By applying force to the second column under cold conditions to deflect it, the distance between it and the first column is shortened in advance. This ensures the expansion of the water beam under hot conditions. The extension is calculated using a formula. When prefabricating the water beam, the distance at the connection is adjusted to compensate for thermal expansion. The columns are then installed and welded step by step.

Benefits of technology

This technology enables efficient, high-quality, and low-cost installation of water beams, simplifies the operation process, reduces safety risks, and improves installation accuracy and service life.
