我队修配间过去修理柴油机轴瓦的方法是采用手工用铬铁一层层的把合金焊上去或使硬模浇注，但前者速度极慢，后者质量不能保证，因此磨损后的轴瓦未能及时修复，堆积了不少旧轴瓦，以致影响了柴油机的修理进度。大跃进中，在破除迷信，敢想敢做的勇气鼓舞下，柴油机工王政敏同志提出使用离心浇注的倡议，得到车间大力支持，经过多次试验后，宣告成功。这种方法的优点是适合于野外
In the past, the repair shop of our team repaired diesel engine bushes by hand using a layer of ferrochromium to weld the alloy up or cast the hard mold. However, the former is extremely slow, and the latter cannot guarantee quality. Therefore, the worn bearing bush cannot be timely. Repair, piled up a lot of old bearings, which affected the progress of the diesel engine repair. During the Great Leap Forward, in the wake of the courage to dare to think and dare to overcome superstition, Comrade Wang Zhengmin, a diesel engine engineer, proposed the initiative to use centrifugal casting and received strong support from the workshop. After many tests, he declared success. The advantage of this method is that it is suitable for the wild
