壳型铸造是把人造树脂砂烧结成薄壳铸型,用来浇注各种铸造合金。铸件铸出后表面光洁,可以代替粗加工,甚至不需要机械加工,既省工又省料。用壳型铸造球墨铸铁十九齿链轮,可以取消加工工序,与砂型铸造比较,能降低成本39%,提高劳动生产率2．5倍(由162分钟/件提高到50分钟/件)。用壳型铸出的联合收割机的可锻铸铁链环及灰铸铁轴承等,铸出后就可直接送到装配车间。
Shell casting is the artificial resin sand sintered into a thin shell mold, used to cast a variety of casting alloys. Casting castings smooth surface, can replace the roughing, do not even need machining, both labor and material. Casting nodular cast iron nineteen tooth sprockets with shell castings eliminates the need for machining operations, reducing costs by 39% and increasing labor productivity by 2.5 times from 162 minutes per piece to 50 minutes per piece, compared with sand casting. Forged combine harvester made of shell cast iron chain link and gray cast iron bearings, etc., after casting can be sent directly to the assembly shop.
