- 摘要:
- 采用消失模(实型)铸造的方式,通过使用一种新型模样材料EMB后,有效解决铸钢的增碳与反喷问题,同时提高了铸钢件稳定的生产成品率。结果表明,这一实用案列解决了困扰多年消失模铸造无法直浇铸钢件,得到高质量低碳的产品,提高成品率等问题。
By using a new type of evaporative material EMB,the problem of carburization of steel castings and back-spurt of liquid steel(due to gasses generated too much and too fast from the foam pattern)were solved.For many years,steel castings cannot be directly poured with EPC,this problem was solved with this method.High quality low-carbon steel castings are obtained,and casting yield is improved.The stability and consistency of steel casting production by EPC is greatly improved.
