我厂从65年 11月至今,一直坚持用水爆清砂法清理ZQSn10—2、ZQSn3－7－5－1、ZQAl9—2青铜和ZHSi80—3、 ZHMn55－3－1黄铜的各类阀体及泵体铸件。水爆总重约296吨。铸型种类有干型、有潮型。铸件壁厚为4~35毫米。铸件轮廓尺寸从76×48×52至720×600×460。单件重量0．5~250公斤。其中50公斤以上大件的水爆成功率在90%以上,20~40公斤中件成功率在75%以上,小件成功率在50~70%。水爆质量稳定,未发现水爆裂纹现象,对产品的物理和机械性能无显著影响。
I plant from November 2005 to date, has always insisted water Qing Qing sand method to clean ZQSn10-2, ZQSn3-7-5-1, ZQAl9-2 bronze and ZHSi80-3, ZHMn55-3-1 various types of brass body And pump castings. Water total weight of about 296 tons. Casting types are dry type, a tide type. Castings wall thickness of 4 to 35 mm. Casting contour size from 76 × 48 × 52 to 720 × 600 × 460. Single weight of 0.5 to 250 kg. Among them, the success rate of over 50kg large-scale water explosion is above 90%, the successful rate of middleware of 20 ~ 40kg is over 75%, and the successful rate of smallware is about 50 ~ 70%. The quality of water burst is stable, no water burst phenomenon is found, and no significant effect on the physical and mechanical properties of the product.
