Bakin karfe elbow ne yadu amfani da shi saboda shi ne mai kyau lalata juriya halaye a petrochemical, kayan aiki, abinci da sauran masana'antu. Ga sana'a bututun kayan aiki masana'antun, bakin karfe elbow a matsayin wani high darajar kara kayayyakin, da ingancin da kyau da mummunan, da high da low samarwa zai kai tsaye shafi kamfanin amfani. A halin yanzu a cikin gida daban-daban bututun kayan aiki masana'antu a lokacin sarrafa bakin karfe kullun da ake amfani da shi ne radial sanyi matsa lamba samar da tsari, amfani da wannan tsari ne yafi la'akari da bakin karfe bututun kayan aiki tsawo mafi girma, a lokaci guda yana da zafi m halaye.
Sakamakon passivation na bakin karfe stamping elbow ya dogara ne akan aikin passivation, kuma ya dogara ne akan kayan bakin karfe stamping elbow kanta, takamaiman tasirin abubuwa sune abubuwan da ke cikin bakin karfe stamping elbow, bakin karfe metallurgy tsari, bakin karfe aiki jihar da sauransu. A cikin abubuwan da aka tsara, chromium da nickel suna cikin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfe. Austenitic, Ferrite jiki irin bakin karfe stamping kullun yana da mafi daidai tsari, mafi kyau passivation, martian jiki irin bakin karfe karfafa da zafi magani karfafa, da metallic tsari ne multi-phase tsari, saboda haka passivation kara karfi. Bakin karfe stamping kullun ta hanyar inji processing da m surface ne mafi kyau passivation, da aka samu workpiece surface karfi, da kuma sandblasting da sauransu, ba su da kyau ga passivation.
Bakin karfe stamping elbow amfani da farantin 60 ~ 70s yafi amfani da saddle karfe da sauran masana'antun samar da A3, 16Mn, tare da bututun diamita karuwa da kuma jigilar matsin lamba karuwa, bututun kayan aiki farantin ƙarfi ba zai iya saduwa da bukatun. Bayan 1980s daban-daban man fetur walda bututun kayan aiki masana'antu fara amfani da bututun karfe farantin da aka samar bisa ga Amurka API ka'idodin, saboda a lokacin da gida bakin karfe hatimi elbow farantin masana'antu fasaha ba balaga, yafi amfani da shigo da farantin.
Duk wani bakin karfe stamped kullun sassa, kamar babu electroplating ko wasu rufi bukatun, yawanci dole ne a pre-treatment (ciki har da acid wanke baƙar fata, polishing, da dai sauransu) bayan passivation magani, don amfani a matsayin kammala kayayyaki ko tattara a cikin sassa. Passivation iya inganta thermal kwanciyar hankali na bakin karfe stamping elbow a cikin muhalli kafofin watsa labarai, hana bakin karfe stamping elbow na gida lalata, sa bakin karfe stamping elbow surface da isasshen tsabtace da kuma kawar da bakin karfe stamping elbow surface zafi aiki oxide.
Baken karfe elbow ne mafi yawan baken karfe, baken karfe dauke da sinadarai sinadarai zai kiyaye baken karfe elbow farfajiyar na dogon lokaci ba lalata, ba tsaki, a tsaftacewa ne mu ma bukatar kula da wadannan bangarori biyu:
A. Dangane da workpiece bukatun da kuma surface yanayin da ake amfani da alkali wanki, ruwa narkewa tsaftacewa, chlorine narkewa yashi spraying, spraying kwayoyi da sauran hanyoyin tsaftacewa;
2, tsabtace bakin karfe elbows, yawanci ba a yi amfani da acid wanke hanyar tsabtace.
Daidai tsabtace bakin karfe elbows, zai iya inganta tsaro aikin amfani da shi, tsawaita shi amfani da sake zagayowar.
Lokacin da aka yi amfani da walda bar ya kamata a kiyaye bushewa, titanium calcium type ya kamata a bushewa a 150 ℃ na sa'a daya, low hydrogen type ya kamata a bushewa a 200-250 ℃ na sa'a daya (ba za a iya bushewa sau da yawa, in ba haka ba, magungunan fata ne mai sauƙi don fashewa da fashewa), don hana walda bar magungunan fata mai man lafiya da sauran datti, don kauce wa walda seams kara carbon abun cik Lokacin walda na kullun, carbide yana fallasa ta hanyar maimaita dumama, rage lalata juriya da kuma aikin inji. Babban karfi bayan walda, yana da sauƙin samar da fashewa. Idan aka yi amfani da wannan nau'in walda bar walda, dole ne a yi a kan 300 ℃ pre-dumama da kuma 700 ℃ a hankali sarrafawa bayan walda. Idan walda kayan aiki ba za a iya yi bayan walda zafi magani, to, ya kamata a zabi chromium nickel bakin karfe walda bar.
