阿尔斯通大齿圈是目前国内研制的最大的经调质处理的铸钢件大齿圈 ,其制造完全按法国阿尔斯通技术要求进行。本文探讨了铸钢大齿圈热处理的关键技术 ,如工艺参数 ,防止淬裂与变形的一些措施。并成功完成了两对 4个半齿圈的调质热处理。
Alstom gear ring is currently the largest development of the quenched and tempered cast steel ring gear, the manufacture of France Alstom completely by the technical requirements. This article discusses the key technologies of heat treatment of cast steel ring gear, such as process parameters, some measures to prevent quench cracking and deformation. And successfully completed the quenching and tempering treatment of two pairs of four half ring gear.
