Hot charging rolling mill

Charging slabs at an elevated temperature into the reheating furnace of the hot rolling mill will save energy. In addition hot charging improves material quality, reduces material losses, enhances productivity (by up to 6%), and may reduce slab stocking. The layout of the plant will affect the feasibility of hot charging because the caster and reheating furnace should be located in proximity
