6250主轴瓦、连杆瓦整体离心铸造南通轴瓦厂用整体离心浇注代替套模离心浇注,来生产柴油机上的较大型轴瓦,即6250主轴瓦和连杆瓦。质量提高了,不必在高温下。操作了,工人少了,有色金属和钢材节约了。〔摘自《机电技术交流》1966№.2〕低压铸造工艺的初步实践探讨天津微电机厂对低压铸造工艺作了实验。设备包括:保温炉、坩墙及其密封盖、浇注管、貯气罐、压缩空气自动控制系统、开启铸型机构、铸型。
6250 main bearing and connecting rod monolithic centrifugal casting Nantong Bearing Factory centrifugal casting instead of using centrifugal casting, to produce diesel engine on the larger bearing, namely 6250 main bearing and connecting rod. Quality has improved, not at high temperatures. Operate, fewer workers, non-ferrous metals and steel saving. 〔Excerpted from the exchange of mechanical and electrical technology 1966 № 2〕 Low-pressure casting process of the initial practice of Tianjin Micro-electrical Works on the low-pressure casting process experiments. Equipment includes: holding furnace, crucible wall and its sealing cap, pouring tube, gas tank, compressed air automatic control system, open the casting mechanism, the mold.
