hordhaca alaabta

Tuubooyinka birta ah ee bacriminta kiimikada waxaa inta badan loo isticmaalaa in lagu soo saaro birta qaab dhismeedka kaarboon oo tayo sare leh, birta qaab dhismeedka alloy iyo birta kulaylka u adkeysata ee cadaadiska sare ee tuubooyinka kululeeyaha uumiga leh cadaadis sare oo ka sarreeya tuubooyinka iyo tuubooyinka kuleyliyaha ayaa ku shaqeeya heerkul sare iyo cadaadis sare, iyo tuubooyinka waxay noqon doonaan oksaydhized iyo daxalka hoos ficil gaaska flue heerkulka sare iyo uumiga.Sidaa darteed, tuubooyinka birta ayaa looga baahan yahay inay yeeshaan xoog waara oo sarreeya, caabbinta oksaydhka sare, iyo xasilloonida hay'ad wanaagsan.Heerarka birta ee la isticmaalo waa: Heerarka qaab dhismeedka kaarboon ee tayada sare leh waa 20G, 20MnG, 25MnG;Darajooyinka birta qaab dhismeedka Alloy 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, iwm;Tubooyinka kululeeyaha ee caadiga ah ee 1Cr18Ni9 iyo 1Cr18Ni11Nb ee ka samaysan birta daxalaysan iyo kulaylka u adkaysta waa in lagu tijaabiyaa tijaabada hydrostatic, flaring iyo flating mid mid marka lagu daro hubinta isku dhafka kiimikada iyo sifooyinka farsamada.Tuubooyinka birta ee gaarka ah ee bacriminta kiimikada waa in la geeyaa xaalada daaweynta kulaylka.

Deegaanka lagu dabaqi karo

Tuubbada gaarka ah ee bacriminta (GB6479-2000) waa birta qaab dhismeedka kaarboon oo tayo sare leh iyo birta daawaha ee birta birta ah ee aan fiicnayn ee ku habboon qalabka kiimikada iyo tuubooyinka heerkulka shaqada ee - 40 ~ 400 ℃ iyo cadaadiska shaqada ee 10 ~ 30Ma.

Dhuumaha daawaynta cadaadiska sare ee qalabka bacriminta (GB6479-2000) waa bir-dhismeedka carbon tayo sare leh iyo birta daawaha birta aan tol lahayn tuubo ku habboon qalabka kiimikada iyo tuubooyinka heerkulka shaqada ee - 40 ~ 400 ℃ iyo cadaadiska shaqada ee 10 ~ 30Ma.

Hordhac wax soo saar

(1) Habka wax-soo-saarka:

Heerkulka isticmaalka tuubooyinka birta ee bacriminta wuxuu ka hooseeyaa 450 ℃, iyo tuubooyinka guriga waxaa inta badan laga sameeyaa duuban kulul ama qabow 10 # iyo 20 # kaarboon ku xiran tuubooyinka birta.

② Dhuumaha birta ee gaarka ah ee loogu talagalay bacriminta waxaa badanaa loo isticmaalaa heerkul sare iyo cadaadis sare, iyo tuubada waxay noqon doontaa oxidized iyo daxalka hoos yimaada ficilka gaasta heerkulka sare iyo uumiga biyaha.Dhuumaha birta ayaa looga baahan yahay inay lahaadaan xoog waara oo sarreeya, oksidation sare iyo caabbinta daxalka, iyo xasilloonida hay'ad wanaagsan.

(2) Ujeedo:

① Tuubooyinka birta ee bacriminta kiimikada waxaa inta badan loo isticmaalaa in lagu soo saaro tuubooyinka derbiga biyaha, tuubooyinka biyaha karkaraya, tuubooyinka uumiga kulul, tuubooyinka uumiga kulul ee kululeeyayaasha, tuubooyinka qiiqa waaweyn iyo kuwa yar yar iyo tuubooyinka lebenka.

② Dhuumaha birta ee sida gaarka ah loogu isticmaalo bacriminta waxaa inta badan loo isticmaalaa in lagu soo saaro tuubooyinka kulaylka badan, tuubada dib u kululaynta, dhuunta hawada, tuubada uumiga, iwm. ee kululeeyaha cadaadiska sare iyo cadaadiska sare.
