Dhuumaha birta kaarboon iyo birta daawaha ah
Shirkaddayadu waxay ku hawlan tahay ganacsiga dhoofinta birta kaarboonka iyo birta daawaha.Dhuumaha Alloy, Dhuumaha birta daawaha ah, Alloy Steel Pipe China, dhuumaha kaarboon, Dhuumaha Birta Kaarboon, Dhuumaha Birta Kaarboon ee Shiinaha.
Ma garanaysaa faraqa u dhexeeya birta kaarboonka iyo birta daawaha?
Birta kaarboon:Inta badan waxa loola jeedaa sifooyinka makaanikku waxay ku xidhan yihiin kaarboonka birta, guud ahaanna ha ku darin wax badan oo walxo bir ah, oo mararka qaarkood loo yaqaan birta kaarboonka ee cad ama birta kaarboon. Birta kaarboon, sidoo kale loo yaqaan birta kaarboon, kaarboonka ka kooban WC in ka yar 2% daawaha kaarboonka birta.
Birta kaarboonka marka lagu daro guud ahaan waxa ku jira xaddi yar oo silikoon ah, manganese, baaruud, fosfooraska waxa loo qaybin karaa iyadoo loo eegayo isticmaalka birta kaarboonka ee kaarboonka qaabdhismeedka birta qaab dhismeedka mashiinka, kaas oo loo qaybin karo birta kaarboon yar (WC ≤ 0.25%), birta kaarboon dhexdhexaad ah (WC 0.25% - 0.6%) iyo birta kaarboonka sare (WC> 0.6%).
Sida laga soo xigtay maadada fosfooraska iyo baaruudka, birta kaarboonka waxaa loo qaybin karaa birta kaarboonka caadiga ah (fosfooraska iyo baaruudku way sarreeyaan), birta kaarboonka oo tayo sare leh (fosfooraska iyo baaruudku way hooseeyaan) birta tayada sare leh (fosfooraska, baaruud hoose).
Birta Alloy:oo ku salaysan birta kaarboonka, hal ama in ka badan ayaa si ula kac ah loogu daraa si loo wanaajiyo adeega iyo habka wax qabad ee daawaynta birta ku salaysan waxaa loo yaqaan birta daawaha. Birta Alloy waxa loola jeedaa birta ka kooban silikoon iyo manganese sida walxo alloying ama walxo deoxidizing, xubno kale oo alloying sida chromium, nikkel, molybdenum, vanadium, titanium, copper, tungsten, aluminium, cobalt, niobium, zirconium iyo xubno kale, iyo qaar ka mid ah sidoo kale waxaa ku jira qaar ka mid ah walxaha aan birta ahayn (sida boron, nitrogen, iwm.) birta.
Marka loo eego qadarka walxaha alloying ee birta, laakiin sidoo kale waxaa loo qaybin karaa birta alloy hoose, daawaha dhexdhexaadka ah iyo birta daawaha sare.
Farqiga ka kooban kiimikada:
(1) Birta Kaarboon: Bir kaarboon yar (C≤0.25%); Bir kaarboon dhexdhexaad ah (C≤0.25 ~ 0.60%); Birta kaarboonka sare (C≤0.60%).
(2) birta daawaha: birta daawaha hoose (wadarta walxaha alloying ≤ 5%); Birta daawaha dhexdhexaadka ah (wadarta guud ee walxaha alloying> 5 ~ 10%); Birta daawaha sare (wadarta guud ee walxaha alloying> 10%.
Faa'iidooyinka birta kaarboon:
Birta kaarboonku waxay leedahay xoog sare, ductility iyo adayg, qiimo jaban, oo loo isticmaalo mishiinada culus ee soo saarista qaybaha culeyska culus. Waxaa lagu heli karaa daawaynta kulaylka oo si fiican loo tuuray guryaha farsamada.
Faa'iidooyinka birta Alloy:
Marka lagu daro birta ku jirta walxaha birta ah ee ka kooban birta kaarboonka, birta kaarboon, silikon kale, baaruud, fosfooraska iyo wasakh kale. Marka lagu daro walxaha kale ee chromium, manganese, molybdenum, titanium, tungsten, vanadium, niobium, boron, silicon iyo nikkel alloy steel si loo gaaro sifooyinka la rabo sida heerkulka sare, barti sare, caabbinta abrasion, xoogga sare, adkaanta sare iyo wixii la mid ah. on. Adkeysiga birta Alloy waxay xirtaan iska caabin, adkeysi, iska caabin daxalka marka loo eego birta kaarboon aad u fiican.
