“工字钢”工字钢也称钢梁,是截面为工字形的长条钢材。其规格以腰高*腿宽*腰厚的毫数表示,如“工16*88*6”,即表示腰高为16毫米,腿宽为88毫米,腰厚为6毫米的工字钢。工字钢的规格也可用型号表示,型号表示腰高的厘米数,如工16#。腰高相同的工字钢,如有几种不同的腿宽和腰厚,需在型号右边加abc予以区别,如32a#32b#32c#等。工字钢分普通工字钢和轻型工字钢,热轧普通工字钢的规格为1-63#。

双频加热淬火技术可以得到更好的仿形淬硬层,对于提高齿轮疲劳强度、减小淬火变形等非常有利。双频感应加热技术双频感应加热是在一个感应圈上同时供给中频和高频能量,即在一个感应圈上施加掺和频率,由一个中频基础振荡迭加一个高频振荡组成。两种频率(MF和HF)的振幅能独自控制,同时能调整MF和HF的输出份额,齿面淬硬程度优于齿根和齿顶,能达到工件的技术要求。这种同时双频感应加热能实现加速奥氏体化,具有热处理质量高、生产率高和变形小的优点,能适应今天的经济发展需求,这要归功于能获得极细小的奥氏体晶粒和加热时间短。
