The Main Function of The Heating Furnace Lining Refractory Material

Our Blog
The main function of the heating furnace is to heat the billets (small square billets, large square billets, slab billets, steel ingots) to 1000-1250℃ (rolling temperature) until they have sufficient plasticity to be rolled into the required section, size, or shape through a hot rolling mill. The required rolling temperature varies depending on the material's chemical composition and grade. Based on the metallurgical properties of the raw materials and productivity, the heating furnace's heating rate must also meet specific requirements…
