我国初轧生产,都是待钢锭完全凝固后再送均热炉进行加热和轧制成坯。如何利用钢锭液芯的凝固潜热,不加热或补充少许热量进行轧制,即进行液芯加热及液芯轧制,这种方法国外已有报导。 1980年攀钢和北京钢铁学院进行沸腾钢液芯加热和液芯轧制的研究工作。北京钢铁学院通过模拟实验和热工理论计算,分析了热芯轧制和普通轧制在变形上的差异以及不同液芯率对各轧制道次的影响,确定液芯率≤6％的范围内进行液芯轧制是可行的。并
China’s initial rolling production, are to be completely solidified after the ingot is sent to the soaking furnace for heating and rolling into a blank. How to use the ingot liquid core solidification latent heat, without heating or add a little heat for rolling, that is, liquid core heating and liquid core rolling, this method has been reported abroad. In 1980 Panzhihua Iron and Steel and Beijing Iron and Steel Institute of boiling liquid steel core heating and liquid core research work. Beijing Iron and Steel Institute through simulation and thermal engineering calculations, the analysis of the hot-core rolling and the difference in the deformation of the ordinary rolling and the different liquid-core rate of each rolling pass, determine the liquid core rate ≤ 6% of the range The liquid core rolling is feasible. and
