- 摘要:
- 随着消失模铸造企业的增多,越来越多的企业已经开始意识到宝珠砂作为消失模填充砂的优越性。宝珠砂粒形接近球形,流动性好并有高的透气性,可充填细长孔、铸件内夹角部分以及复杂内腔部分,也比较容易震实;另外宝珠砂由于有高强度,使得它具有不破碎、不粉化、回用性能好,也能降低铸件生产成本,改善车间劳动环境。With the lost foam industry booming, more and more foundries had begun to realize that ceramic sand as the elimination of the advantages of the backing sand. Ceramic sand has near spherical shape, good flowability and a higher permeability, it can be filled with elongated holes, steep located castings and the complex part with cavities. Ceramic sand is relatively easy to shakeout although it has higher strength while molding. Ceramic sand is difficult to be broken while reclamation so it generates less sand powder. Also, ceramic sand can reduce the cost of casting production, improve the workshop labor environment.
