我厂主要生产工矿备件,常遇到轮形锡青铜铸件的生产问题。 众所周知,锡青铜的结晶温度范围较宽,极易产生显微缩孔和缩松。我厂过去生产蜗轮及轮缘铸件,采取水平浇注。冒口多,铸造成品率较低,仅达53％;切除冒口的劳动强度增大,成本较高,经济效益不理想。 针对这一问题,笔者对轮形件采取倾斜浇注进行了探索。认为:轮形锡青铜铸件采 I plant mainly produces mining spare parts, often encountered round tin bronze casting production problems. As we all know, tin bronze crystallization temperature range, easy to produce micro-shrinkage and shrinkage. I plant in the past the production of wheels and wheel flange castings, to take the level of pouring. Riser, cast low yield, only 53%; removal of riser labor intensity increases, the higher the cost, the economic benefits are not satisfactory. In response to this problem, the author of the wheel to tilt casting to explore. Think: Wheel tin bronze casting mining
