摘要
拉法基都江堰水泥设备Φ4.8m×52m回转窑Φ6400mm超大铸钢齿圈是目前国内生产的最大的调质齿圈之一。该齿因采用GS—34CrMo4V钢,为三幅板单齿圈结构,其制造不但难度大,而且涉及工序多。本文根据大齿圈热加工制造过程,分析了如何保证内部质量、尺寸精度、铸造及调质变形等技术难点,采取了适当的铸造、热处理工艺和各工序质量保证措施,成功制造了一套特大型齿圈。所生产的齿圈满足拉法基公司、洪堡公司、唐山安装工程公司三方的技术要求。该齿圈的生产技术达到了国内先进水平,为集团公司今后生产同类产品提供了宝贵的技术经验。
On the Basis of the manufacturing process for large gear ring, the technical problems such as how to assure the internai soundness, dimensional accuracy, casting and quenching deformation, has been resolved. With the proper casting process, heat treatment process, and quality assurance measures, a suit of gear ring has been made successfully.
