低合金高强度耐磨履带板铸造工艺研究

Casting Process Study on Low Alloy and High Strength Wear-resistant Track Pad

针对高锰钢铸件在非强烈冲击环境下使用的不足,结合该履带板产品的结构特征及使用工况,选用了材质强度更高的低合金耐磨钢,利用CAE模拟软件对铸造工艺进行模拟优化,通过产品试制对产生的铸造缺陷进行分析,优化改进铸造工艺,设计合理的热处理工装,最终得到了符合使用要求的产品。该低合金耐磨履带板使用寿命长、生产成本低,具有很大的推广价值。

In order to solve the shortage of high manganese steel under the condition of low- intensity-impacting,the more harder low-alloy wear-resisting steel was choosen to get the wear-resistant products which are more fit with the operating inquirement.Considering the structure features and use conditions of these castings,we use the simulation software of CAE to imitate the casting techniques, and analyzes the casting defects through casting trial products to optimize and improve the casting techniques, and design the most reasonable facility for heat treating.This kind of low-alloy wear-resistant track pad has a longer service life with a lower production costs.
