一、引言高锰钢由于具有很高的韧性,所以被广泛地应用于破碎和研磨设备中的易损件制造。高锰钢部件在运转过程中有两种磨损形式:一是冲击磨损;一是摩擦磨损。因此,高锰钢部件的使用寿命决定于此种配件在运转过程中的加工硬化程度,这就直接与被粉碎的物料硬度及部件所受的冲击负荷的大小有关。分析水泥机械中高锰钢配件的磨损情况得知:此配件在运转过程中的加工硬化程度并不理想,如φ1250双转子反击式破碎机的转子转速为600转/分,粉碎石灰石块为1000毫米。经
First, the introduction of high manganese steel due to its high toughness, it is widely used in crushing and grinding equipment in the manufacture of wearing parts. High manganese steel parts in the operation of the process there are two forms of wear: First, impact wear; First, friction and wear. Therefore, the service life of high manganese steel parts depends on the degree of work hardening of such parts during operation, which is directly related to the hardness of the material being crushed and the impact load on the part. Analysis of wear and tear of high manganese steel parts in cement machinery that: this part in the process of hardening the degree of work is not ideal, such as φ1250 double rotor impact crusher rotor speed of 600 rev / min, pulverized limestone block of 1000 mm . through
