摘要
当球墨铸铁管在用水冷金属型生产中大口径管时,采用离心水冷的生产模式,冷却较快,管模容易产生裂纹,造成管模使用寿命偏低。通过改善离心机机身循环水路和操作方式,使管模使用寿命得到明显提升。
When ductile Cast iron pipe is produced with water-cooled metal mold for medium and large diameter pipes,centrifugal water-cooled production mode is adopted,which cools quickly,and the pipe mold is easy to crack,resulting in low service life of the pipe mold.By improving the circulating water circuit and operating mode of the centrifuge body,the service life of the pipe mold has been significantly improved.
