Cold mirgina: shi ne aiki na matsa lamba da kuma mikewa ductility. Narkewa na iya canza sinadarai na kayan ƙarfe. Cold mirgina ba zai iya canza sinadaran abun da ke ciki na karfe, da nada za a sanya a cikin sanyi mirgina kayan aiki Rolls da ake ji daban-daban matsi, da nada za a yi sanyi birgima zuwa daban-daban kauri, sa'an nan ta karshe karewa yi, sarrafa nada kauri daidaito. cikakken daidaito a cikin siliki 3.

Annealing: Ana sanya coil ɗin sanyi a cikin tanderun ƙwararrun ƙwararrun ƙwararru, mai zafi zuwa wani yanayin zafi (digiri 900-1100), kuma ana daidaita saurin murɗawar tanderun don samun taurin da ya dace. Kayan abu don zama mai laushi, saurin annealing yana jinkirin, mafi girman farashin daidai. 201 da 304 sune bakin karfe na austenitic, a cikin tsari na cirewa, buƙatar zafi da sanyi don gyara ƙungiyar ƙarfe na tsarin sanyi ya lalace, don haka annealing yana da matukar mahimmanci. Wasu lokuta tsutsa ba ta da kyau don samar da tsatsa cikin sauƙi.

The workpiece ne mai tsanani zuwa wani predetermined zazzabi, gudanar da wani lokaci na wani lokaci sa'an nan a hankali sanyaya karfe zafi magani tsari. Manufar annealing shine:

1 don inganta ko kawar da karfe a cikin simintin gyare-gyare, ƙirƙira, mirgina da tsarin walda wanda ya haifar da lahani iri-iri da damuwa na ƙungiya, don hana lalacewar aikin aiki, fatattaka.

2 tausasa kayan aikin don yankan.

3 tace hatsi, inganta kungiyar don inganta kayan aikin injiniya na kayan aiki. Shirye-shiryen ƙungiya don maganin zafi na ƙarshe da yin bututu.

Slitting: bakin karfe nada, a yanka a cikin daidai nisa, don haka don gudanar da wani ƙarin zurfin aiki da bututu yin, slitting tsari bukatar kula da kariya, don kauce wa scratching da nada, slitting nisa da kuskure, ban da slitting da dangantaka tsakanin tsarin yin bututu, slitting na karfe tsiri bayyana a kan tsari na gaba da burrs, chipping kai tsaye rinjayar da yawan amfanin ƙasa na welded bututu.

Welding: mafi muhimmanci tsari na bakin karfe tube, bakin karfe ne yafi amfani da argon baka waldi, high mita waldi, plasma waldi, Laser waldi. A halin yanzu mafi amfani shine argon baka waldi.

Argon baka waldi: garkuwar gas mai tsabta argon ko gauraye gas, high waldi quality, mai kyau weld shigar azzakari cikin farji, da kayayyakin a cikin sinadaran, nukiliya da kuma abinci masana'antu ana amfani da ko'ina.

High-mita waldi: tare da mafi girma tushen wutar lantarki, domin daban-daban kayan, waje diamita kauri bango na karfe bututu iya cimma wani mafi girma waldi gudun. Idan aka kwatanta da waldawar Argon Arc, shine mafi girman saurin walda fiye da sau 10. Misali, samar da bututun ƙarfe ta amfani da walda mai ƙarfi.

Waldawar Plasma: yana da ƙarfi mai ƙarfi mai ƙarfi, shine amfani da ginin musamman na fitilar plasma wanda babban zafin plasma ke samarwa, kuma ƙarƙashin kariya ta hanyar haɗakar iskar gas mai kariya. Misali, idan kaurin kayan ya kai 6.0mm ko sama da haka, yawanci ana buƙatar waldawar plasma don tabbatar da cewa an haɗa kabu ɗin.

Bakin karfe welded bututu a cikin murabba'in tube, rectangular tube, m tube, siffa tube, da farko daga zagaye tube, ta hanyar samar da zagaye tube tare da wannan kewaye sa'an nan kafa a cikin daidai tube siffar, kuma a karshe siffata da kuma mikewa da kyawon tsayuwa. .

Bakin karfe tube samar sabon tsari ne in mun gwada da m, mafi yawansu an yanke da hacksaw ruwan wukake, da yanke zai samar da wani karamin tsari na gaba; dayan kuma wani band saw yankan ne, misali, babban diamita bakin karfe bututu, akwai kuma batch na gaba, gaba daya batch na gaba da yawa a lokacin da ma'aikata bukatar maye gurbin siga.

gogewa: Bayan an samar da bututu, ana goge saman da injin goge goge. Yawancin lokaci, akwai matakai da yawa don maganin saman samfurin da bututun ado, polishing, wanda aka raba zuwa haske ( madubi), 6K, 8K; kuma ana raba sanding zuwa yashi zagaye da yashi madaidaiciya, tare da 40#, 60#, 80#180#, 240#, 400#, 600#, don biyan buƙatun abokan ciniki daban-daban.
