针对铅、锑熔点、密度不同的特点,采用电阻炉熔化,倒包搅拌;树脂砂消失模造外形,水玻璃砂刮板制芯,设计芯铁,减少用砂,增加排气,完成大型薄壁铅锑合金铸件的铸造。 For the lead, antimony melting point, the density of different characteristics, the use of resistance furnace melting, pouring mixing bag; resin sand disappeared mold shape, water glass sand scraper core, the design of core iron, reduce sand, increase exhaust, complete large thin wall Lead-antimony alloy casting casting.
