目前铸管生产主要有三种(立式、离心、连续)铸管方法,其中连续铸管是最有发展前途。它具有设备简单,制作、维护容易;建厂投资少、速度快;产品质量好;劳动生产率高;成本低;劳动环境好,劳动强度小;易于实现机械化和自动化等优点。这是符合党的多快好省建设社会主义总路线的。连续铸管是铸管生产新工艺,经过几年来的生产实践,已得到了巩固和提高,并以单 At present, there are mainly three kinds of pipe casting (vertical, centrifugal, continuous) casting method, of which continuous casting is the most promising. The utility model has the advantages of simple equipment, easy manufacture and maintenance, low investment in construction, high speed, good product quality, high labor productivity, low cost, good working environment and small labor intensity, and the advantages of mechanization and automation. This is in line with the party’s general line of building a socialist country with more speed and more efficiency. Continuous casting is a new pipe casting process, after several years of production practice, has been consolidated and improved, and a single
