AI Technical Summary

Technical Problem

In the hot rolling process, excessive temperature difference caused by the contact between the slab and the water beam results in black marks on the water beam, affecting product quality. Furthermore, the accumulation of iron oxide scale increases friction, shortens the service life of the water beam, and reduces heat transfer efficiency.

Method used

Design a water beam structure including an upper water pipe on the longitudinal beam, a lower water pipe on the longitudinal beam, a supporting structure, multiple heat-resistant sliders and a heat-resistant insulation layer. Through the staggered and symmetrically distributed heat-resistant sliders and heat-resistant insulation layer, heat and cooling water are evenly distributed, reducing heat loss and improving structural stability and cooling efficiency.

Benefits of technology

It effectively reduces black marks on the water beams, improves product quality, extends the service life of the water beams, enhances cooling efficiency and energy utilization efficiency, and strengthens structural stability and operational safety.
