F-01蜡基中温模料是机械部沈阳铸造所和石油部抚顺石油炼制研究所共同研制成功的熔模精铸用模料。具有高强、低缩、热稳定性适中等中温模料的物化性能(见附表)。用此代替目前普遍使用的石蜡-硬脂酸低温模料,可以提高模料的成品率,提高零件的尺寸精度及表面光洁度,可在精铸厂现有生产情况下推广应用。每吨成本比石蜡-硬脂酸模料降低400元以上。该模料研制成功后,在哈尔滨汽轮机厂、无锡叶片厂进行生产验证,表明具有良好的综合工艺性能,可在汽轮机、燃汽轮机等类似的产品厂广泛应用。目前,在洛阳拖拉机厂熔模精铸生产线
F-01 wax-based medium temperature mold is the Ministry of Machinery Foundry and the Ministry of Oil Fushun Petroleum Refinery Institute jointly developed a successful investment casting material. With high strength, low shrinkage, moderate thermal stability of the physical and chemical properties of the mold (see table). This instead of the currently widely used paraffin - stearic acid low temperature mold, mold can improve the yield, improve the dimensional accuracy of parts and surface finish, can be cast in the existing production applications promotion. The cost per ton lower than the paraffin - stearic acid mold more than 400 yuan. After the successful development of the mold, Harbin Steam Turbine Factory, Wuxi leaf factory production verification, that has a good overall process performance, in steam turbines, gas turbines and other similar products widely used. At present, Luoyang tractor plant investment casting line
