Development of multi-stage storage technology for high-temperature waste heat during steel continuous casting

In order to solve the problem that the heat supply and demand do not match the time and place in the waste heat recovery of continuous casting slabs in the existing iron and steel enterprises. This work aims to use the principle of phase change energy storage for multi-stage recovery and storage of high-temperature waste heat from continuous casting slabs, which can not only fundamentally realize the matching and utilization of heat in time and space, but also ensure efficient heat recovery efficiency. It greatly reduces environmental thermal pollution, has great promotion value and energysaving benefits
