连续铸造生产铝带坯的新工艺,由于省去了传统的热轧工序,从而能节能与减少投资。因此近二十年来发展很快,无论在工业先进的国家,还是发展中国家都得到了广泛应用。目前世界上有几种类型的连续铸造机在使用。但是使用最多的是二辊式的连铸机。二辊式连铸机的结晶器是活动型的,熔融金属的热量靠两个水冷辊套的热传导来散发。这种间接冷却方式,使得单位时间内散发出的热量有限,金属凝固速度缓慢,晶粒显得粗大。此外,铸造的合金品种也受到一定的限制。而西德铸造技术公司(Technica—Guss Gmb H)和西德的VAW公司共同
Continuous casting of aluminum billet production of new technology, eliminating the need for the traditional hot-rolled process, which can save energy and reduce investment. Therefore, it has developed rapidly in the past 20 years and has been widely used both in advanced countries and in developing countries. There are several types of continuous casting machines currently in use in the world. However, the most used is a two-roll continuous casting machine. Two-roll caster mold is active, the heat of molten metal by two water-cooled roll sleeve heat conduction to emit. This indirect cooling, making the heat emitted per unit of time is limited, the metal solidification slow, coarse grains appear. In addition, the cast alloy varieties are subject to certain restrictions. Technica-Guss Gmb H and VAW in West Germany are common
