滑板铸件缩陷缺陷的解决

摘要

分析了床鞍滑板铸件产生缩陷的原因,并提出了相应的解决措施.通过在熔炼过程中调整废钢、生铁加入量,以调节铸件含碳量,使铸件凝固收缩率减小;更改分型面及浇注位置等一系列工艺措施,使铸件的废品得到了有效地控制.%The reason causes depression of skateboard bad saddle was analyzed, and the corresponding solutions were put forward. By taking a series of technical measures the rejection rate was reduced effectively, and obtained a certain economic benefit. The measures are that adjusting lhe addition amount of scrap steel and pig iron in smelting process to adjust carbon content of casting products, and changing the location of parting face and gates, so as to decrease the solidification shrinkage rate.
