钻井液旋流器的球铁铸造

The Casting of Well-drilling Liquid Spinner in Ductile Iron

石油钻井液旋流器,首次采用中锰抗磨球铁铸造成功,其平均磨损率达0.18mm/100hr,取得比高铬铸钢、丁晴橡胶旋流器优越的抗磨性,比聚氨酯旋流器价格低40％的经济性,赢得用户满意的效果,为华北油田研制新型12″除砂器解决了关键性问题。

Well-drilling liquid spinner is successfully cast in the medium-manganese antiwear ductile iron for the first time. Lts average wearing rate is 0.18mm per 100 hours. It has a better antiwear property than high-chromium cast steel and acrylonitrile rubber, while it is 40% cheaper than polyester rubber. So it satisfies eustomers and makes the key problem solved, which We meet in study and production of new type 12' Sand-remover for north-china oilfield.
