Abubuwan da ke haifar da lalata na bakin karfe grating

1 Rashin ajiya mara kyau, sufuri da ɗagawa
A lokacin ajiya, sufuri da ɗagawa, bakin karfe grating zai lalace lokacin da ya ci karo da tarkace daga abubuwa masu wuya, tuntuɓar karafa iri-iri, ƙura, mai, tsatsa da sauran gurɓata. Hada bakin karfe da sauran kayan aiki da kayan aiki mara kyau don ajiya na iya gurɓata saman bakin karfe cikin sauƙi da haifar da lalata sinadarai. Yin amfani da kayan aikin da ba daidai ba na sufuri da kayan aiki na iya haifar da bumps da tarkace a saman bakin karfe, ta yadda za a lalata fim ɗin chromium na bakin karfe da samar da lalatawar lantarki. Amfani mara kyau na hoists da chucks da aiki mara kyau na iya haifar da lalata fim ɗin chromium na bakin karfe, haifar da lalatawar electrochemical.
2 Ana saukewa da samar da albarkatun kasa
Abubuwan da aka yi birgima na ƙarfe suna buƙatar sarrafa su zuwa ƙarfe mai faɗi don amfani ta hanyar buɗewa da yanke. A cikin sama aiki, da chromium-arziki oxide passivation film a saman bakin karfe grating ya lalace saboda yankan, clamping, dumama, mold extrusion, sanyi aiki hardening, da dai sauransu, haddasa electrochemical lalata. A karkashin yanayi na al'ada, fuskar bangon karfe da aka fallasa bayan an lalata fim ɗin wucewa zai amsa tare da yanayin don gyaran kai, sake samar da fim ɗin wucewar oxide mai arzikin chromium, kuma ya ci gaba da kare substrate. Koyaya, idan saman bakin karfe bai kasance mai tsabta ba, zai hanzarta lalata bakin karfe. Yankewa da dumama yayin aiwatar da yankan da clamping, dumama, mold extrusion, sanyi aiki hardening a lokacin kafa tsari zai haifar da m canje-canje a cikin tsarin da kuma haifar da electrochemical lalata.
3 Shigar da zafi
A lokacin da masana'antu tsari na bakin karfe grating, lokacin da zafin jiki ya kai 500 ~ 800 ℃, da chromium carbide a cikin bakin karfe zai hazo tare da hatsi iyaka, da intergranular lalata zai faru kusa da hatsi iyaka saboda da rage a cikin chromium abun ciki. Thermal conductivity na austenitic bakin karfe ne game da 1/3 na na carbon karfe. Zafin da ake samu a lokacin walda ba zai iya tarwatsewa da sauri ba, kuma ana tara yawan zafi mai yawa a cikin yankin walda don ƙara yawan zafin jiki, wanda ke haifar da lalata tsaka-tsakin ƙarfe na baƙin ƙarfe da wuraren da ke kewaye. Bugu da ƙari, Layer oxide Layer ya lalace, wanda ke da sauƙi don haifar da lalata electrochemical. Saboda haka, yankin walda yana da haɗari ga lalata. Bayan an gama aikin walda, yawanci yakan zama dole a goge bayyanar walda don cire baƙar toka, spatter, walda da sauran kafofin watsa labarai waɗanda ke da saurin lalata, sannan ana yin ƙwanƙwasa da jiyya akan weld ɗin da aka fallasa.
4. Zaɓin da ba daidai ba na kayan aiki da aiwatar da aiwatarwa yayin samarwa
A cikin ainihin tsarin aiki, zaɓi mara kyau na wasu kayan aiki da aiwatar da aiwatarwa na iya haifar da lalata. Misali, rashin cikar cire wucewar wucewar ƙura a lokacin walda na iya haifar da lalata sinadarai. Ana zaɓar kayan aikin da ba daidai ba lokacin tsaftace slag da spatter bayan waldi, yana haifar da rashin cikawa tsaftacewa ko lalacewa ga kayan iyaye. Ba daidai ba nika na hadawan abu da iskar shaka launi lalata surface oxide Layer ko mannewa na tsatsa-samun abubuwa, wanda zai iya kai ga electrochemical lalata.
