特殊钢生产品种不能适应国民经济发展的需要,已经愈益成为一个突出的问题。许多新建和改建的机器制造工厂例如量具刃具制造工厂、机床制造工厂、仪表制造工厂、发电机制造工厂、汽车制造工厂、拖拉机制造工厂等等已经或者即将陆续提前投入生产,旧有的机器制造工厂也将扩大生产品种,它们需要大量的多种多样的新品种钢材。这些新品种钢村中有一部分例如冷轧钢板、大型钢材等是需要在新建及改建工厂增添新的设备来系统加以解决;但是也有很大一
Special steel production varieties can not meet the needs of the development of national economy, has become an increasingly prominent issue. Many new and rebuilt machinery manufacturing plants, such as gage cutting tool manufacturing plants, machine tool manufacturing plants, instrumentation manufacturing plants, generator manufacturing plants, automobile manufacturing plants, tractor manufacturing plants, etc., have been or will soon be brought into production one after the other. Older machine building factories It will also expand the production of varieties, they need a large number of a variety of new varieties of steel. Some of these new varieties of steel mills, such as cold-rolled steel sheets, large-sized steel, etc., are required to be systematically addressed by adding new equipment to new and rebuilt factories; however,
