SYSTEM AND METHOD FOR ENDLESS HOT ROLLING

摘要

PURPOSE: An endless hot rolling system and a method which prevents winding errors due to the rapid cutting of an ultrathin strip is provided to reduce an equipment investment cost and remove the high speed cutter facility of the winding device. CONSTITUTION: An endless hot rolling system comprises a high-speed continuous caster facility, a roughing mill(200), a heater(400), a rolling mill(700), a winding device(900), and a cutter(600). The high-speed continuous caster facility produces the slab of the first thickness. The roughing mill rolls slab to the rolling bar of the second thickness thinning than the first thickness. The upper heating apparatus heats the rolling bar. The rolling mill rolls the heated rolling bar to the strip of the third thickness thinning than the second thickness. The winding device reels the strip. The cutter is at least arranged among the domain of the between heater and roughing mills.
