熔融铝经一次操作就铸成较小尺寸的铸条,在经济上永远是合理的。铸条非常适于热轧成更小尺寸(与冷轧比较可节省动力),亦适于卷成卷后进行冷轧。对于生产某种等级的半成品铸条和铝板的中小型工厂来说,更是引人注目,因为在这些工厂中可以将费用较低的设备安装在面积很小建造费不大的厂房中。长期以来,工程界人士就致力于改进连续 Molten aluminum cast by a single operation of the smaller size of castings, the economy will always be reasonable. Casting is very suitable for hot rolling into smaller size (compared with cold rolling can save power), is also suitable for roll after cold rolling. It is even more compelling for small and medium-sized factories to produce some sort of semi-finished cast strip and aluminum, where lower-cost equipment can be installed in smaller, less-expensive plants. For a long time, engineering people are committed to improving continuity
