针对窄而厚的特殊形状热镀锌合金锭在铸造时易出现上表面缩孔、上表面热裂纹和内部孔洞等缺陷,以及铸锭淋雨后会在热镀锌现场出现炸锅事故,着手对铸模及铸造工艺进行改进,最后铸造出合格产品,消除了安全隐患。 For the narrow and thick special shape of hot-dip galvanized alloy ingots in the casting prone to shrinkage on the surface, the upper surface of the hot cracks and internal holes and other defects, as well as the ingot after the shower will be hot dip galvanized field fry accidents, proceed The mold and casting process to improve and finally cast a qualified product, eliminating the security risks.
