在提高产品质量的群众运动中,为了改变高锰钢衬板质量差、使用寿命低的状况,在厂党委领导下组织了“三结合”小组,以歪头山矿自磨机格子板为重点开展了提高衬板使用寿命的攻关活动。经过一阶段的工作,取得了显著效果,歪头山自磨机格子板使用寿命提高三倍多。我们遵照毛主席关于“一切真知都是从直接经验发源的”的伟大教导,在工作开始时,我们首先分头深入车间、小组通过和工人师傅共同劳动和调查研究,初步了解和掌握了高锰钢衬板生产中的几个主要问题。在高锰钢冶炼方面,出钢和浇注温度控制不严,
In mass movement to improve product quality, in order to change the poor quality of high manganese steel liner, low life conditions, under the leadership of the factory party committee organized a “triple combination” group to tilt head mine from the mill lattice board as the focus Launched to improve the service life of liner research activities. After a period of work, has achieved remarkable results, tilt head mountain mill from the plate more than three times the service life. We follow Chairman Mao’s great teaching that “all true knowledge is derived from direct experience.” At the beginning of the work, we first went to the workshop one by one. The group, through joint labor and investigation with the master workers, gained an initial understanding and mastery of the high manganese steel Lining production of several major issues. In high manganese steel smelting, tapping and pouring temperature control lax,
