我厂是一个处理含铁、铜、钴矿石的多金属选矿厂,采用浮——磁联合流程。由于厂房布置分散,流程较为复杂,各车间之间及车间内部各种管道、溜槽既多且长,总长约3500米左右。原采用钢(或铸铁)管、槽,磨损利害,漏浆严重,更换频繁,不仅浪费了大量的钢材和检修工时,而且经常影响生产,甚至被迫停机检修。广大工人、干部、技术人员以阶级斗争为纲,高举“鞍钢宪法”的旗帜,决心改变这一被动局面。我们在国家建委大力推广使用铸石制品的热潮中,在兄弟矿山使用铸石制品 I plant is a deal with iron, copper, cobalt ore multi-metal concentrator, the use of floating - magnetic joint process. As the plant layout scattered, the process is more complex, various workshops within the workshop and various pipes, chutes both more and longer, total length of about 3,500 meters. The original use of steel (or cast iron) pipe, slot, wear and tear, leakage of serious, frequent replacement, not only wasted a lot of steel and maintenance man hours, and often affect the production, and even forced downtime maintenance. The broad masses of workers, cadres and technicians take the class struggle as the key link and hold high the banner of “Ansang Steel Constitution” and are determined to change this passive situation. We vigorously promote the use of cast stone products in the National Construction Committee boom, the use of castings in the brothers mine products
