保温冒口已经成为改善铸件质量,提高铸件工艺实收率,节约能源消耗的有效措施,因此,越来越得到国内外铸造工作者的普遍重视。但是,由于保温材料价格较贵,保温冒口的应用受到限制。为了扩大保温冒口的应用范围,采用了价格低廉的炉渣基保温混合料,以浇 Insulating riser has become an effective measure to improve the quality of castings, improve the actual yield of castings and save energy consumption. Therefore, more and more attention has been paid to foundry workers at home and abroad. However, the application of thermal insulation is limited due to the more expensive insulation materials. In order to expand the scope of application of thermal riser, using a low-cost slag-based insulation mixture to pour
