摘要
为缩短生产周期,降低生产成本,同时达到提高涨紧轮铸件质量的目的,利用Pro CAST软件对矿用涨紧轮铸造方案进行模拟优化.研究表明:在冒口根部安放保温套,可以减缓冒口内金属液的凝固使该处热节上移,同时延缓铸件上部金属液的凝固,促进自下而上顺序凝固的实现.从而使冒口根部的缩孔缩松缺陷脱离铸件上表面,底部的缩孔缩松缺陷大部分成堆分布于铸件底部轴心处.因此,对于涨紧轮,通过Pro CAST模拟,证明侧底面切线引入式浇注并且铸体带保温套的铸造工艺为最优方案.
Tensioner casting simulation and optimization scheme is conducted by using the Pro CAST software in order to research on reducing the period of manufacture and costs of castings, and at the same time, improving the quality of mine tensioner. By analyzing the temperature filed of filling and solidification process, in the casting system, the riser roots and tensioner pulley casting bottom which were most easily discovered has prone shrinkage. In this study, four plans are applied. In our study： setting the insulation sleeve in the root part could reduce solidification of the melting metallic liquid in the riser moves up. On the other hand, the solidification speed of casting part could slow down. As a result, the solidification has better consequence from root part to upper part. By adding a insulation sleeve, the shrinkage defects could disappear on the surface of casting. All the shrinkage defects only concentrated on the axis of casting bottom. The optimization is proved by Pro CAST software. Addition of insulation sleeve and side bottom surface casting type could optimize the casting quality.
