Abstract

PURPOSE:To regulate the amount of scale generating on the surface of steel material and, at the same time, to prevent flaws from generating on the surface of steel material at the rolling, by controlling the concentration of oxygen in the atmosphere inside the furnace, when the steel material is heated to the temperature for rolling in the heating furnace of multizone type.
