采用废钢增碳技术,利用合金化元素 Cu 和 Sn 强化基体组织,通过完善球化、孕育处理等工艺措施,制备出铸态 QT600-10高强高韧性球墨铸铁。试验表明:采用废钢增碳生产合成球铁,选择合适的化学成分,其铸态抗拉强度≥600 MPa,断后伸长率≥10%。
採用廢鋼增碳技術,利用閤金化元素 Cu 和 Sn 彊化基體組織,通過完善毬化、孕育處理等工藝措施,製備齣鑄態 QT600-10高彊高韌性毬墨鑄鐵。試驗錶明:採用廢鋼增碳生產閤成毬鐵,選擇閤適的化學成分,其鑄態抗拉彊度≥600 MPa,斷後伸長率≥10%。
채용폐강증탄기술,이용합금화원소 Cu 화 Sn 강화기체조직,통과완선구화、잉육처리등공예조시,제비출주태 QT600-10고강고인성구묵주철。시험표명:채용폐강증탄생산합성구철,선택합괄적화학성분,기주태항랍강도≥600 MPa,단후신장솔≥10%。
Using waste-steel recarburization technique and enhancing the cast matrix with alloying elements of Cu-Sn,high strength,high-toughness cast QT600 -10 synthetic ductile iron was pro-duced through strengthening spheroidization and inoculation treatment.Experimental results show that choosing appropriate chemical composition,the as cast tensile strength and the elongation of the cast QT600 -10 synthetic ductile iron is higher or equal to 600MPa,and is higher or equal to 10%, respectively.
