随着汽车工业、航空工业的发展,金属薄板的品种和数量不断增加。金属薄板的生产方法也日益受到重视。金属薄板的一般生产方法是,以金属铸锭或扁坯为坯料进行热轧。这种生产方法已经用了六七十年,它的主要缺点是轧机设备的投资大,用均热炉或再热炉加热坯料需要大量的热能,轧制过程消耗很多能量,材料利用率不高等等。近年出现了一些薄板生产的新方法,例如; With the development of automobile industry and aviation industry, the variety and quantity of sheet metal are increasing. Metal sheet production methods are also increasingly valued. The general method for producing sheet metal is to hot-roll a metal ingot or slab as a raw material. This production method has been used for six or seventy years, its main disadvantage is the large investment in rolling mill equipment, with a soaking furnace or reheat furnace heating billet requires a lot of heat, the rolling process consumes a lot of energy, material utilization is not high Wait. In recent years some new methods of sheet production have emerged, for example;
