摘要
本文研究了诸因素对石膏型混合材料性能的影响，选择出合理的、廉价的造型材料配方及焙烧工艺．试验结果表明，这类混合材料尺寸稳定性高、强度适中、耐热性好，其焙烧工艺操作简便，易于控制．
After careful investigation of various factors affecting plaster-bonded moulding mixture properties,reasonable and cheap mixture formulation and roasting processes are given. Test results show that the mixture are precise in keeping size, moderate in strength,superior in heat-resistance and the roasting processes are covement in application.
