为加快发展我国冶金工业钢的热挤压生产,上海重型机器厂已为广西河池钢厂设计制造了一条无缝钢管热挤压生产线。该生产线已投入生产,其主要设备是2000吨挤压机和700吨穿孔机,这两台压机的工作行程次数是参考西德 Schloemann 公司设计的3150吨挤压机和1000吨穿孔机数据,适当缩小为120次/时;从加热坯锭到穿孔直至挤压完毕的周期为30秒。 In order to speed up the hot extrusion production of China’s metallurgical industry steel, Shanghai Heavy Machinery Factory has designed and manufactured a seamless steel pipe hot extrusion production line for Guangxi Hechi Steel Plant. The production line has been put into production, the main equipment is 2000 tons of extrusion presses and 700 tons of piercing machine, the work of the two presses the number of trips is based on West Germany Schloemann company designed 3150 tons of extruder and 1000 tons of piercing machine data, Appropriately reduced to 120 times / hour; from heating the billet to the perforation until the extrusion cycle is completed for 30 seconds.
