陕西柴油机厂在浇铸铸钢件过程中,积极采用保温冒口新工艺,今年以来浇铸钢件126吨,共节约资金一万九千多元。以前,该厂浇铸钢件多采用自制的普通砂型冒口,工艺出品率低,冒口重量占铸件重量的70%以上。大量冒口钢水回炉,造成了人力、财力的浪费。在“双增双节”运动中,该厂技术人员将陕西压延设备厂保温冒口厂生产的
In the process of casting cast steel, Shaanxi Diesel Engine Factory actively adopts the new technology of thermal insulation riser, and casts 126 tons of steel pieces this year, saving a total of over 19,000 yuan. In the past, the factory used steel casting more common self-made sand-type riser, craft production rate is low, riser weight accounted for more than 70% of the weight of the casting. A large number of riser molten steel back to the furnace, resulting in a waste of manpower and financial resources. In the “double by double” campaign, the plant technicians Shaanxi Calendering Plant insulation riser plant production
