Improvement of fuel consumption and maintenance of heating furnaces using a modified heating pattern

This article studies the transient heat conduction in a slab when passing through various sections of the furnace,and focuses on the thickness of the scale layer formed on the slab.The transient heat conduction behavior ora slab in various sections of the heating furnace is analyzed using the Laplace transformation method,including the pre-heating zone,the first heating zone,the second heating zone,and the soaking zone.The heating pattern of the furnace is then modified to reduce fuel consumption.The simulation results show that the scale layer formed on the slab significantly influences the quality of the hot rolled coil formed,and how the furnace parameters affect the efficiency of the furnace and the quality of the coil.
