离心复合高铬钢轧辊差温热处理工艺

摘要

离心复合高铬钢轧辊热处理工艺对轧辊组织和性能有较大的影响，特别是对芯部组织和性能的影响，不恰当的热处理工艺会降低轧辊芯部球墨铸铁强度和韧性，增大了轧辊在使用过程中的事故率。高铬钢轧辊差温热处理工艺克服了高温处理对轧辊芯部球墨铸铁组织和性能的影响，大大降低了轧辊使用中的事故率。%The centrifugal compound high-chromium steel roll heat treatment process on the microstructure and mechanical properties of roll has a great influence, especially the influence on the microstructure and mechanical properties of core, improper heat treatment process can reduce core nodular cast iron roll strength and toughness, increases the roll in the accident rate in the process of use.High chromium steel roll is poor warm treatment technology to overcome the high temperature treatment on the microstructure and mechanical properties of ductile cast iron roll core, greatly reduce the accident rate in the roll to use.
