我厂在承担了巴氏合金轴瓦的浇注任务中,经十余年摸索,找到了一种既简便、又能保证质量的浇注方法。成品率由过去的不到50％,现在达到95％以上。 一、清洗轴瓦铁壳 一般浇注前,烧去旧轴瓦原被磨损的合金,在铁壳表面上搪一层锡,以免浇不牢。搪锡时,因铁壳加热温度不易掌握,往往需几经加热、刷酸、涂锡,才能完成搪锡工序。搪锡工序所耗工时,占整个浇注轴瓦工时的一半以上,十分耗时费事。
I plant in the commitment of Babbitt bearing the casting task, after more than ten years of exploration, to find a not only easy, but also ensure the quality of the casting method. Yield from less than 50% in the past, now more than 95%. First, clean the bearing shell iron Before casting, burn the original bearing alloy worn, enamel a layer of tin on the surface of the iron shell, so as not to cast is not strong. When tin is tinned, it is not easy to grasp the heating temperature of the iron shell, and it usually takes several hours to heat, brush acid and tin to finish the tin-lining process. Lining process takes time, accounting for the entire castings more than half the working hours, very time-consuming and trouble-free.
