摘要
介绍了大平面平板衬的消失模铸造,分析了埋箱过程中模样变形的原因,对比了三种浇注系统对平板衬充型过程的影响。结果表明,在消失模铸造中,埋箱时将模样立放且分批加入干型砂,能有效地避免平板衬模样在埋箱过程中变形;针对不同规格的平板衬,可以不设置冒口,通过合理地选择浇注系统,能够生产出合格的铸件。
The EPC porcess of big plane plate lining was introduced, the reason of the mould deformation was analyzed in the process of burying the box, the influence of three kinds of gating system on the filling process of plate lining was contrasted. The results show that, when burying the box, the mould is standed and the molding sand is joined in batches in EPC casting, it can avoid effectively the deformation of the mould. Aimed at different specification plate linings, the qualified casting can be produced through choosing reasonable gating system without riser.
