熔体处理是铝铸造中的关键问题之一它对半成品质量起决定性作用。由于对铝材的要求越来越高(表面质量、机械性能等)因此总是采用某种方法来处理熔体。铝熔体处理费用是一笔不可低估的开支,尤其是增加了新的环保措施后又大大增加了开支。目前采用的方法有许多种,各有优点和不足。总的来说,取得的经验是不完全的,由于各自的条件不同,各自的问题也不同,因而许
Melt processing is one of the key issues in aluminum casting, which plays a decisive role in the quality of semi-finished products. Because of the increasing demands on aluminum (surface quality, mechanical properties, etc.), there is always a certain way to handle the melt. The cost of aluminum melt processing is an undisputable cost, especially since the addition of new environmental measures has substantially increased the costs. There are many methods currently used, each with its advantages and disadvantages. In general, the experience we have gained is incomplete. Due to their different conditions, their respective problems are different. Therefore,
