一、前言铸铜生产是机械制造工业的先锋。在为加速社会主义建设促进钢铁工业和整个国民经济发展的进程中,许多冶炼设备、起重运输设备以及其它重型机械都需要大量的铸钢件。同时,铸钢件本身又是国家钢产量的一个组成部分,因此,大量挖掘铸钢生产潜力具有非常重要的意义。而挖掘铸钢生产潜力的最有效措施之一就是采用湿型铸造。 First, the foreword Copper production is a pioneer in the machinery manufacturing industry. In order to speed up the socialist construction and promote the development of the iron and steel industry and the entire national economy, many smelting equipment, hoisting equipment and other heavy machinery require a large amount of steel castings. At the same time, steel casting itself is an integral part of national steel production, therefore, to tap the potential of steel production is of great significance. One of the most effective measures to tap the potential of cast steel production is to use wet casting.
