Ƙarfe Mai Kyau Mai Kyau Mai Kyau Mai Ruwan Ƙarfe Na Ƙarfe na Sinanci Mai Dutsin Karfe Na Karfe

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 jujjuyawar zafi mai zafi. Wadannan su ne ainihin matakansa:

Danyen Kayan Shiri
Danyen kayan da aka ci gaba da yin jifa ko billet, yawanci kauri 150-300 mm.
Wurin yana fuskantar tsaftacewa (misali, ƙulla wuta ko niƙa) don cire ma'auni da lahani da tabbatar da ingancin mirgina.
Dumama
Ana ciyar da katako a cikin tanderun katako mai tafiya kuma ana zafi zuwa 1100-1300 ° C don cimma haɓakawa 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 katako a cikin injin niƙa mai jujjuyawa (misali, niƙa mai tsayi biyu ko huɗu) cikin sanduna na tsaka-tsaki mai kauri na 30-50 mm.
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 lebur don tabbatar da daidaito da daidaiton girma.
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 daga zafin jiki na ƙarshe (kimanin 800 ° C) zuwa zafin ɗaki ta hanyar sarrafa adadin ruwa da ƙimar sanyaya (misali, 30-50°C/second).
Tsarin sanyaya kai tsaye yana rinjayar microstructure na coil (misali, ferrite zuwa pearlite rabo) da kaddarorin inji.
Nadi
An raunata tsiri a cikin coils ta amfani da naɗaɗɗen tsumma da coiler. Ana sarrafa tashin hankali tsakanin 100-500 N/mm² don tabbatar da madaidaicin siffa 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 sun haɗa da tsinke don cire ma'auni ko sutura kamar galvanizing ko alumini.
Annealing: Yana inganta ductility (misali, recrystallization annealing kafin sanyi birgima). Flattening: Mirgina a ƙananan matsa lamba yana kawar da samar da albarkatu a cikin samfuran lebur kuma yana haɓaka ƙarewar ƙasa.
Ingancin Dubawa da Marufi: Ana bincika samfuran don girma, kaddarorin injina, da ingancin saman kafin a naɗe, haɗe, da lakafta su bisa ga ƙayyadaddun abokin ciniki.
