在毛主席“备战、备荒、为人民”的伟大方针指引下,我们破除迷信,解放思想,土法上马,于1971年7月试制成功用MC尼龙6做φ2100毫米圆锥破碎机的φ720毫米中心轴衬套。这种大型尼龙塑料衬套在东鞍山烧结厂破碎车间1号中破碎机上安装使用已近三年多,破碎矿石520万吨,没有损坏,衬套内壁光滑,与相对运转的动锥轴表面光滑无擦伤痕迹;1971年11月,在4号细破碎机安装使用这种尼龙衬套,共运行5040小时,破碎矿石62.4万吨,由于油变质而烧焦报废;其余8台破碎机使用MC尼龙6衬套,其寿命平均为9个月以上。生产实践表明,使用MC尼龙6塑料衬套代替铜套的优点是:
Under the guidance of Chairman Mao’s great guideline of “preparing for war, preparing for war and for the people,” we broke away from superstition, emancipated our minds and started the trial of indigenous laws. In July 1971, we successfully produced a φ720 mm central axis with a φ2100 mm cone crusher using MC nylon 6 bushing. This large nylon plastic bushing in the East Anshan Sintering Plant crushing plant on the 1st crusher installed to use nearly three years, 5.2 million tons of broken ore, there is no damage, the liner wall smooth, and the relative movement of the smooth surface of the shaft No scratches marks; November 1971, No. 4 fine crusher installed using this nylon bushing, a total of 5040 hours of operation, crushing the ore of 624,000 tons, as a result of the deterioration of oil scorched scrap; the remaining eight crusher MC Nylon 6 bushing, the average life expectancy of 9 months or more. Production practice shows that the use of MC nylon 6 plastic bushings instead of copper has the advantage of:
