烧结机高铬篦条铸造生产实践

Production Practice of High Chromium Grate Bar Casting for Sintering Machine

为保证烧结机的正常运行,对高铬篦条铸造工艺进行改进,通过合理控制篦条消失模尺寸,设计了浇注系统及砂箱,强化了冶炼、浇注及开箱时关键工序的控制措施,使篦条综合性能得到很大提高,铸造篦条合格率达98%以上,产量提高了50%以上,能够满足烧结生产需要。

In order to ensure the normal running of sintering machine,the casting process of high chromium grate bar was improved.By way of reasonably controlling the size of grate bar lost foam,designing casting system and flask and strengthening critical processes such as smelting,pouring and knocking out,the comprehensive properties of grate bar were improved by big margin.The qualification rate of grate bar casting was up to over 98% and production increased by more than 50%.Sintering production could be well met.
