A specially-designed addition agent is used instead of coal dust in green molding sand for the trial production of impact molding line made by GF company.
本文对于我厂在新铸造车间引进的GF气冲造型线上所用的型砂不添加煤粉。
Results show that the density of green parts under dynamic molding conditions is obviously higher than under steady molding conditions.
实验结果表明,各动态成型条件下的型坯密度明显大于稳态成型条件下的密度。
The growing thermal load of green sand, the quicker recirculation times and the increased requirements on the quality of molding material make new demands on the molding sand preparation.
潮模砂日益增长的热负荷,更快的循环时间以及对造型材料质量要求的提高,对型砂制备提出了更高的要求。
