Qhov sib txawv ntawm Tsawg Carbon Steel Thiab High Carbon Steel

• Carbon steel yog subdivided rau hauv:

① qis carbon steel, cov ntsiab lus carbon tsawg dua 0.25%;

② nruab nrab carbon steel, carbon cov ntsiab lus ntawm {{0}}.25% rau 0.6%;

③ siab carbon steel, cov ntsiab lus carbon ntau dua 0.6%.

• Cov pa roj carbon tsawg (cov hlau me me) rau cov ntsiab lus ntawm cov pa roj carbon tsawg dua 0.25% ntawm cov pa roj carbon steel, vim nws tsis tshua muaj zog, tsis tshua muaj zog thiab mos, nws tseem hu ua cov hlau mos. Nws suav nrog feem ntau ntawm cov pa roj carbon monoxide zoo tib yam thiab ib feem ntawm cov pa roj carbon zoo steel, feem ntau yog tsis kho cua sov rau engineering structural qhov chaw, qee qhov yog carburised thiab lwm yam kub-kho rau hnav-resistant mechanical qhov chaw.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

• Nruab nrab carbon steel kub ua hauj lwm thiab txiav kev ua tau zoo, tsis zoo vuam kev ua tau zoo. Lub zog, hardness yog siab dua me ntsis steel, thaum lub plasticity thiab toughness yog qis dua me ntsis steel. Tsis tuaj yeem kho cua sov, ncaj qha siv cov khoom siv txias txias, cov khoom siv txias txias, kuj tuaj yeem siv tom qab kev kho cua sov. quenched thiab tempered nruab nrab carbon steel muaj zoo tag nrho txhua yam khoom. Ua tiav qhov siab tshaj plaws hardness ntawm HRC55 (HB538), σb rau 600 ~ 1100MPa. yog li nyob rau hauv nruab nrab lub zog theem ntawm ntau yam kev siv, nruab nrab carbon steel tau siv dav tshaj plaws, ntxiv rau cov khoom siv hauv tsev, tab sis kuj muaj coob tus siv hauv kev tsim khoom ntawm ntau yam khoom siv.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

• Cov pa roj carbon ntau (High Carbon Steel) feem ntau hu ua cov cuab yeej hlau, cov ntsiab lus carbon ntawm {{{0}}.60% mus rau 1.70%, tuaj yeem quenched thiab tempered, vuam kev ua tau zoo heev. Hammers, crowbars, thiab lwm yam los ntawm cov ntsiab lus carbon ntawm 0.75% ntawm cov hlau tsim; tej cuab yeej xws li xyaum xyaum, ntsia hlau ntsia hlau thiab reamers, thiab lwm yam. los ntawm cov ntsiab lus carbon ntawm 0.90% mus rau 1. 00% ntawm steel manufacturing.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

• Kev sib piv ntawm Vuam Cov Khoom Ntawm Cov Me Me thiab Cov Carbon Steels

1. Lub vuam kev ua tau zoo ntawm cov hlau tsuas yog nyob ntawm nws cov tshuaj muaj pes tsawg leeg. Lub ntsiab tseem ceeb tshaj plaws yog cov pa roj carbon, uas txhais tau hais tias cov pa roj carbon ntau hauv cov hlau txiav txim siab nws qhov weldability. Feem ntau ntawm lwm cov alloying ntsiab nyob rau hauv cov hlau kuj tsis zoo rau vuam, tab sis cov degree ntawm lawv cov cawv feem ntau me me dua carbon.
2. General me me steel weldability yog qhov zoo, feem ntau tsis tas yuav siv cov txheej txheem tshwj xeeb ntsuas, tsuas yog nyob rau hauv qhov kub thiab txias, tuab phaj lossis muaj cov kev xav tau siab dua, tsuas yog yuav tsum tau siv alkaline electrode vuam, thiab tsim nyog preheating. Thaum cov pa roj carbon thiab sulfur cov ntsiab lus hauv cov hlau me me yog ib feem ntawm qhov txwv siab, ntxiv rau cov kev xav tau ntawm cov khoom siv hluav taws xob zoo qis, siv cov kev ntsuas xws li preheating thiab tom qab cua sov, nws yuav tsum yog qhov kev xaiv tsim nyog ntawm daim ntawv bevel. , txo qhov fusion piv, thiaj li tiv thaiv kub tawg.
3. Qhov nruab nrab carbon steel vuam muaj ib tug nyiam rau txias cracking, siab dua cov ntsiab lus ntawm cov pa roj carbon monoxide, qhov ntau dua qhov yuav ua rau harden lub tshav kub cuam tshuam cheeb tsam, qhov ntau dua qhov nyiam txias cracking, qhov phem dua qhov weldability. Nrog rau kev nce hauv cov ntsiab lus carbon ntawm cov khoom siv hauv paus, cov ntsiab lus carbon ntawm cov hlau weld kuj yuav nce raws li, ua ke nrog cov txiaj ntsig tsis zoo ntawm sulfur, nws yog ib qho yooj yim los tsim cov kub tawg hauv qhov vuam. Yog li ntawd, nruab nrab carbon steel vuam yuav tsum siv zoo tawg tsis kam alkaline electrodes, thiab siv cov kev ntsuas xws li preheating thiab tom qab cua sov kom txo tau cov nyiam tawg.
4. High-carbon steel welding, vim cov ntsiab lus siab ntawm cov hlau no, vuam yuav ua rau muaj kev ntxhov siab ntau heev, vuam qhov cuam tshuam rau qhov kub thiab txias ntawm qhov sib txawv ntawm qhov tawv thiab qhov txias txias yog ntau dua, thaum lub vuam tseem muaj ntau dua thermal cracking. , high-carbon steel welding tshaj qhov nruab nrab-carbon steel feem ntau yuav tsim thermal tawg, yog li no hom steel weldability yog qhov phem tshaj, nws tsis yog nyob rau hauv cov qauv ntawm cov weld yog tsis siv, tsuas yog rau casting muab tub lim los yog overlay vuam. Tom qab vuam, lub vuam yuav tsum tau tempered kom tshem tawm kev ntxhov siab, txhim kho lub koom haum, tiv thaiv cov kab nrib pleb thiab txhim kho kev ua haujlwm ntawm cov vuam.
