熔模铸造高强度铸铁毛坯的工业生产,从1968年就开始了。目前,美国、德意志民主共和国和日本均已用熔模铸造生产了高强度铸铁件。捷克、罗马尼亚和巴西等国对此也很感兴趣。 高强度铸铁的特殊工艺性和陶瓷型的结合,无论是铸造合金或者是铸造方法的优越性都得到充分的利用。高强度铸铁与钢比较起来,有高的流动性;低的浇注温度;收缩率小。所有这些使熔模铸造可获得特别复杂的薄壁铸件,它的精度和表面光洁度提高,
Industrial production of investment cast high strength cast iron rough began in 1968. At present, the United States, the German Democratic Republic and Japan have all manufactured cast iron parts with high strength by investment casting. Countries such as Czech Republic, Romania and Brazil are also very interested. High strength cast iron special technology and the combination of ceramic type, whether it is cast alloy or casting method advantages have been fully utilized. High-strength cast iron and steel compared to a high liquidity; low pouring temperature; shrinkage rate is small. All of these make investment casting to obtain particularly complex thin-wall castings with increased precision and surface finish,
