Farashin masana'anta High Quality Karfe Coil Hot Rolled Karfe Coil

Tsarin samarwa na zafi-birgimakarfen karfemabuɗin haɗin gwiwa ne a masana'antar ƙarfe. Ya fi samar da billet ɗin ƙarfe zuwa siffar farantin da ake buƙata ta hanyar jujjuyawa mai zafi. Waɗannan su ne ainihin matakansa:

Danyen Kayan Shiri
Danyen kayan ya kasance ko dai dutsen simintin gyare-gyare ko kuma furanni, yawanci kauri 150-300 mm.
Wurin da aka rufe yana fuskantar tsaftacewa (misali, ƙulla wuta ko niƙa) don cire ma'auni da lahani don tabbatar da ingancin mirgina.
Dumama
Ana ciyar da katako a cikin tanderun katako mai tafiya kuma a yi zafi zuwa 1100-1300 ° C don isa ga ingantawa da haɓaka ductility.
Dole ne a sarrafa lokacin dumama da daidaiton zafin jiki don guje wa zafi mai zafi ko ƙasa da ƙasa.
Tashin hankali
Ana mirgina dutsen cikin sanduna tsaka-tsaki mai kauri 30-50 mm a cikin injin niƙa mai juyi (misali, niƙa mai tsayi biyu ko huɗu).
Bayan kowace wucewar birgima, za a iya yin jujjuyawar ruwa mai matsa lamba don cire saman oxide Layer.
Ƙarshe
Matsakaicin sanduna suna shigar da injin ƙarewa (yawanci wanda ya ƙunshi manyan injina shida ko bakwai huɗu ko shida), inda a hankali a hankali za a rage su zuwa kauri (misali, 1.2-25 mm) ta ci gaba da birgima. Ana amfani da tsarin sarrafa ma'auni ta atomatik (AGC) da tsarin kula da fa'ida don tabbatar da daidaiton girma da fa'ida.
A yayin aikin birgima, naɗaɗɗen na buƙatar sanyaya da lubrication don hana lalacewar zafi da lalacewa.
Sanyi
Tsarin sanyaya laminar yana saurin kwantar da tsiri na ƙarfe daga zafin jiki na ƙarshe (kimanin 800 ° C) zuwa zafin ɗaki ta hanyar sarrafa adadin ruwa da yanayin sanyaya (misali, 30-50°C/second).
Tsarin sanyaya kai tsaye yana rinjayar microstructure (misali, ferrite zuwa pearlite rabo) da kaddarorin inji na nada.
Nadi
An raunata tsiri na ƙarfe a cikin coils ta amfani da naɗaɗɗen tsummoki da coiler. Ana sarrafa tashin hankali tsakanin 100-500 N/mm² don tabbatar da siffa mai tsauri kuma babu sako-sako da coils.
Yawan zafin jiki na murɗawa ana sarrafa shi tsakanin 550-700 ° C don haɓaka kaddarorin.
Bayan-Processing
Maganin saman: Maganin saman ya haɗa da zazzagewa don cire ma'aunin oxide ko sutura kamar galvanizing ko alumini.
Annealing: Yana inganta ductility (misali, recrystallization annealing kafin sanyi birgima). Flattening: Ƙarƙashin raguwar mirgina yana kawar da samar da ƙarfe mai laushi kuma yana inganta ƙarewar ƙasa.
Ingancin dubawa da marufi: Muna bincika girma, kaddarorin inji, da ingancin saman kafin murɗawa, haɗawa, da lakabin samfurin bisa ga ƙayyadaddun abokin ciniki.
