Abstract: PURPOSE:To stabilize the quality of a cast strip product and the conduction of production by setting each heating zone along each roll at the pouring basin part in the continuous casting apparatus having twin roll for cooling. CONSTITUTION:A tundish 1, nozzle 3 and trough 4 are arranged, respectively so as to form the pouring basin part 5in one pair of cooling rolls 6, 6.
