Hanyoyi don hana oxidative decarburization na tanderun lantarki na gwaji kayan aiki

1. Manna shafi saman

Hanyar yin amfani da manna a saman kayan aiki yana da ƙananan farashi, mai sauƙi a cikin aiki, kuma baya buƙatar kayan aiki na musamman.

Ko da yake hanyar yin amfani da manna yana da sauƙi kuma mai dacewa, akwai haɗari na fashewa da peeling na manna a lokacin aikin dumama, wanda har yanzu yana iya haifar da oxidation na gida da decarburization. A lokaci guda, manna yana wanzu a saman kayan aikin, wanda zai shafi ingancin quenching, kuma aikin da aka kashe ba shi da sauƙin tsaftacewa. Kuma, aikin aikin da aka rufe da manna zai haifar da hayaki mai yawa lokacin zafi, wanda zai shafi amfani da wutar lantarki.

2. Gawayi foda ɗaukar hoto

Yi amfani da gawayi foda, ko ƙara dace adadin baƙin ƙarfe filings da slag (girman hatsi 1 ~ 4mm) zuwa ga gawayi foda a matsayin m wakili, rufe workpiece da zafi da shi a cikin tanderun, wanda zai iya yadda ya kamata hana workpiece daga oxidizing decarburization dauki. Wannan hanya mai sauƙi ne kuma mai sauƙi don aiwatarwa, kuma farashin yana da ƙasa, amma lokacin zafi yana buƙatar ƙarawa yadda ya kamata.

3. Rigakafin na musamman-siffa workpieces

Ga wasu na musamman-dimbin yawa workpieces, yana da wuya a hana oxidative decarburization ta manna shafi ko gawayi foda shafi. A wannan lokacin, ana iya sanya wani adadin ƙwayar gawayi a cikin tanda tare da tire, sa’an nan kuma za a iya ƙara yawan zafin jiki na tanderu zuwa matsayi mafi girma. Zazzabi yana buƙatar zama sama da 30 ~ 50 ℃, don haka gawayi yana hulɗa da iska don samar da isasshen adadin carbon, don haka iskar gas a cikin tanderun yana cikin yanayin tsaka tsaki, sannan ana ɗora kayan aiki na musamman, wanda zai iya rage ko ragewa. hana sabon abu na oxidative decarburization.
