摘要

针对消失模铸造焚烧炉炉排的冷隔、夹杂缺陷

从白模密度、浇注温度、浇注方式等多个方面进行综合分析。经多次试验表明

提高浇注温度至1620℃

采用侧注式浇注可以有效避免冷隔夹杂缺陷的产生。

Abstract

Origination of cold shut and inclusion in grate of incinerator by lost foam casting was analyzed.The effects of pattern density

pouring temperature and pouring ways on the defects were comprehensively analyzed.The optimized processing schemes were presented to effectively eliminate the cold shut and inclusion defects in the grate by lost foam casting

including increasing pouring temperature to 1 620 ℃ and side-pouring way.
