Research on the Hot Charging Regulation Optimization of Reheating Furnace with Hot Rolling

The off-line simulation calculation model of slab reheating furnace and the steel temperature model of the slab heating and the heat balance were combined according to the billet tracking test and the heat equilibrium test. The temperature of slab in the furnace was simulated and the temperature schedule was optimized according to the condition of different furnace and different steel grades and different slab charging temperature. The temperature system optimization of the different steel grades under the different hot charging temperature with consumption minimum were achieved, which provided a theoretical reference for energy saving and scientific operation on the heating furnace.
