摘要

通过对规格为 664mm/ 480mm× 3870mm

质量为 45 0 0kg的大型硅钢钢板卷取机套筒的生产

对这种大型钢套筒在生产中常出现的裂纹、缩松、缩孔等缺陷进行了分析研究

发现选择合适的涂料及合适的涂覆工艺

选取 2种离心铸造转速

第一速度保证铸件成型

第二速度保证铸件在铸型内有足够出型强度

基本解决了钢套筒的裂纹、缩松、缩孔等缺陷

Abstract

The casting defects

such as crack

porosity and shrinkage hole

often revealed in the steel sleeve with 664 mm/480 mm×3 870 mm and the weight of 4 500 kg of winding machine for silicon steel plate were analyzed in centrifugal casting. It is found that the selection of pertinent coating and spreading technology

and optimization of two varieties of rotating speeds for forming process at first speed and for sufficient strength of casting release at second speed can eliminate mentioned above casting defects.
