近年来,我厂为全国啤酒行业提供了大量的过滤、灌装设备。86年,数十种ZHSi80—3硅黄铜铸件产量达455吨。现将中小硅黄铜铸件浇冒口系统设置经验介绍如下: ZHSi80—3硅黄铜液相线温度低(890℃),流动性好,结晶区间窄。根据以上特点,设计硅黄铜铸件浇冒口系统一般的原则是:顺序凝固,集中补缩,加大冒口,平稳充填。不少资料介绍的充填方式是:浇注系统多采用中注式,内浇口从分型面
In recent years, I plant for the national beer industry provides a large number of filtration, filling equipment. In 1986, dozens of ZHSi80-3 silicon brass castings produced 455 tons. Now small and medium-sized castings of silicon castings Riser system settings are introduced as follows: ZHSi80-3 silicon brass liquidus temperature is low (890 ℃), good liquidity, narrow crystallization range. According to the above characteristics, the design of silicon brass casting Riser system, the general principle is: the order of solidification, focus on shrink, increase riser, smooth filling. A lot of information on the filling method is: pouring system used in the injection, the gate from the parting surface
