汽缸套离心铸造用GJB高效精炼变质剂研究
摘要
<正> 目前国内离心铸造气缸套废品率高
工艺收得率低
造成材料能源的巨大浪费
为了提高离心铸造气缸套质量
国内外开展了多方面的研究工作。我们经过两年研究
通过试验设计、筛选优化
研制成功了气缸套离心铸造用GJB系列高效精炼变质剂。该剂集精炼、变质与合金化功能于一体
利用离心力场条件对铁水进行型内精炼、瞬时孕育与微量合金化
大大提高了精炼变质效果
可显著减少铸造缺陷
改善金相组织
提高机械强度与耐磨性能
并可提高铸件工
Abstract
GJB is a new type of modifier which has strong and multiple effects on the iron melt for the centrifugal casting of cylinder sleeves. It has the virtue of its comprehensive abilities of refining
inoculation and alloying
the effect is obvious. As well as its function and mechanism are investigated in this paper.
