Modulation and High Frequency Quenching of Rack

类别:Industry News   发布时间:2019-09-04 10:42:00   浏览:246 次

For mechanical parts, such as shaft parts, transmission parts, before or after processing, some processing is needed to adjust the internal structure, so in many cases, various processing has become an indispensable method for these parts. The modulation treatment and high frequency quenching of rack are often used. So what role do they play? Lets have a look with the square rack knitting.



Modulation Processing of Rack



First understand the rack modulation processing, rack is the combination of quenching and high temperature tempering. This processing method is to adjust the hardness, mild and wayward treatment of rack blank. This treatment is generally processed before mechanical processing, first change some of the internal properties of rack blank, then mechanical processing.



High Frequency Quenching Treatment of Rack



High frequency quenching treatment is hardening treatment of rack surface. Generally speaking, for carbon structural steels with carbon content of more than 35%, such as 45%, 40Gr and other materials, the hardness of rack factory after high frequency treatment will meet the requirements of use. In this way, the hardness after modulation treatment can not reach the hardness of quenching treatment, but at high frequency. Quenching knowledge is directed at the tooth surface.
