几年来,我厂經受了史无前例的无产阶級文化大革命的战斗洗礼和两条路綫斗爭的严峻考驗,高举毛主席亲手制定的《鞍钢宪法》的光輝旗帜,活学活用毛主席的哲学思想,不断地提高全厂革命职工的阶級斗爭和路綫斗爭觉悟,大大地促进了黑色金属压鑄工艺的試驗工作。无产阶級文化大革命以来,我厂在长春光机研究所的协助下,采用边試驗,边生产的方針,已經提供大批播种机用的压鑄伞齿輪和玻璃輥道用的传动伞齿輪。經过6年多的田间試驗和使用证明:压鑄伞齿輪使用寿命高于机械加工的伞齿輪。这种黑色金属压鑄工艺可以在农机、汽車、机床、采矿和国防等工业部門广泛应用。
Over the past few years, our factory has stood the test of unprecedented baptism of proletarian cultural revolution and the severe test of the two lines of struggle. We hold high the banner of Chairman Mao’s constitutional philosophy, To raise the class struggle and route struggle consciousness of the entire factory revolutionary workers, greatly promoted the experimental work of ferrous metal die-casting process. Since the Great Proletarian Cultural Revolution, with the assistance of Changchun Institute of Optics and Optoelectronics, our factory has adopted a large number of die-cast bevel gears for gear seeders and transmission bevel gears for glass roller conveyors with the principle of side-trial and side-by-side production. After more than 6 years of field trials and the use of proven: die-casting bevel gear service life is higher than the bevel gear. This black metal die-casting process can be widely used in agricultural, automotive, machine tools, mining and defense industries.
