圆筒形铸件缩松缩孔的产生原因及解决方法

The Analyzing and Approach of Shrinkage and Porosity in Cylindrical Iron Castings

针对圆筒形铸铁辊体冒口端面产生的缩松、缩孔缺陷，进行了举例说明、系统分析，找到了缺陷产生的原因及影响因素。通过解决措施的应用与实施，有效地克服了圆筒形辊体铸件冒口端面产生的缩松、缩孔缺陷，同时应用到其它大型圆筒形铸件中，都得到了良好效果。

The shrinkage and shrinkage porosity defects under the riser of cylindrical iron roller were analyzed systematically. The causes and factors were summarized. With the proper approaches, the shrinkage defects under risers can be reduced. The techniques has also applied to make other large cylindrical castings.
