针对实际生产中大型球墨铸铁件因为存在夹渣而报废的情况,研究了大型球墨铸铁件的过滤技术,并总结了过滤器的过滤机理、过滤器种类及过滤器布置原则。生产实践表明:采用过滤技术后大型球墨铸铁件的夹渣问题得到了有效地解决。 In view of the actual production of large ductile iron scrap scrap because of the existence of the situation, the study of large ductile iron filter technology, and summed up the filter filter mechanism, filter type and filter layout principles. Production practice shows that: the use of filtration technology after the large ductile iron casting slag problem has been effectively resolved.
