Abstract

PURPOSE:To remove easily strongly adhered primary scale by a high pressure water jet descaler by suppressing as much as possible the cooling of steel by providing a heat insulating cover, a heater, etc., on the path of steel from the heating furnace for steel to descaler in the rolling of steel by a hot rolling mill. CONSTITUTION:When the steel 8 is heated at the heating furnace 3 and then rolled by the hot rolling mill 1, the primary scale on the surface is removed by the descaler using a high pressure water jet in advance. However, the primary scale adhered to such steels as aluminium-killed steel, silicon-killed steel, etc., is difficult to remove. Since the removing rate of scale by the descaler 4 is better the higher the temperature of steel, the heater 9, e.g., burner, etc., is placed between the heating furnace 3 and the descaler 4, or the temperature of steel is kept by the heat insulating cover 5 to keep its surface temperature at more than 1000 to 1050 deg.C and then the steel is sent to the descaler 4. Thus, the primary scale on the killed steels can be easily removed.
