介绍了国内外建筑用排水管的发展现状。论述了整条铸铁排水管离心铸造生产线的结构、工作原理和主要设备的技术参数。根据离心铸造铸铁排水管螺旋成形工艺特点,通过大量试验,确定了铸铁排水管的生产工艺。生产实践表明,铸铁管质量达到国际标准要求,与传统砂型手工造型铸管相比,社会经济效益可观。 The current status of construction drainage pipes at home and abroad is introduced. Discusses the structure, working principle and technical parameters of the main equipment of centrifugal cast iron casting line. According to the characteristics of the spiral casting process of centrifugal cast iron cast iron drainage pipe, through a large number of tests, the production process of cast iron drainage pipe was determined. Production practice shows that the quality of cast iron pipe to meet the requirements of international standards, compared with the traditional hand-molded sand casting, considerable social and economic benefits.
