In this paper, the influence of high temperature quenching on micrstructure and mechanical properties of 5CrW2Si steel has been studied. It was shown that, when the austenitizing temperature was increased, a large amount of lath martensite was obtained after quenching and the steel possessed excellent synthetic mechanical properties after tempering at 500℃. As the temperature increased from 900℃ to 1000—1050℃, the strengths, ductilities U-notch impact toughness, and fracture toughness were increased and optimum...

In this paper, the influence of high temperature quenching on micrstructure and mechanical properties of 5CrW2Si steel has been studied. It was shown that, when the austenitizing temperature was increased, a large amount of lath martensite was obtained after quenching and the steel possessed excellent synthetic mechanical properties after tempering at 500℃. As the temperature increased from 900℃ to 1000—1050℃, the strengths, ductilities U-notch impact toughness, and fracture toughness were increased and optimum strengthening and toughening effects were obtained, the service life of the punched matrix for hot rolling locomotive wheel and Tyre was remarkebly increased and the better heat treating processing variables are provided for hot shear knives.

本文研究了高温淬火对5CrW2Si钢组织和性能的影响。研究指出,捉高加热温度,淬火后获得板条马氏体,经500℃回火后具有优良的综合机械性能。加热温度由常规900℃提高至1000~1050℃,强度、塑性、U型缺口冲击韧性及断裂切性均可较大幅度的提高,获得最佳强韧化效果,使车轮和轮箍用热压字头的使用寿命显著提高,并为热剪刀片等提供了较佳的处理工艺参数。

By means of infrared temperature measuring system, based on the specified lengths of shearing plate, the device calculates the hot shearing lengths of plate automatically, and uses it to control the width measuring system of linear induction synchronizer for automatic shearing,

本文介绍的装置采用红外测温系统,根据所剪板子的定尺,自动计算热态补偿尺寸及剪切尺寸,以此控制直线式感应同步器的测宽系统,自动剪切。

This paper analyzas the cause of hot shear cracking in alloy 3J1.

本文分析了3J1合金在热剪切时发生开裂的原因,结果表明,合金锻坯心部存在Ti元素偏析;导致富Ti区热塑性下降,剪切时,富Ti区一旦暴露就产生开裂。
