PURPOSE:To eliminate load of compressed strain to solidified shell and to improve the quality by maintaining under controlling circumferential velocity of pinch rolls or pressurizing rolls drawing a strip from a pouring basin part to 1-1.05 times of running velocity of a belt. CONSTITUTION:The metal strip 11 is directly introduced to the pressurizing rolls 12 from the pouring basin part 4 or the pinch rolls are arranged between the pouring basin part 4 and the pressurizing rolls 12, to apply a little rolling reduction force to the metal strip. The operation is executed under maintaining the circumferential velocity of the pinch rolls or the pressurizing rolls 12 in the range of 1-1.05 times of the circumferential velocity of the belt 1. In this way, the surface quantity of the product is improved and the operational efficiency is improved. |
