Cov pa roj carbon carburized hlau yuav muab faib ua cov roj carbon carburized steel thiab alloy carburized carbon steel
Nov 01, 2020| Cov pa roj carbon carburized hlau yuav muab faib ua cov roj carbon carburized steel thiab alloy carburized carbon steel
1) Ntawm cov pa roj carbon carburized carbon steels, 15 thiab 20 steels feem ntau siv. Tom qab carburizing thiab kho cua sov, lawv cov npoo tawv tuaj yeem ncav cuag 56-62HRC. Txawm li cas los xij, vim tsis muaj lub siab tawv, nws tsuas yog siv rau cov qhov me me uas tsis muaj qhov tseem ceeb lub zog, tsis tshua muaj kev ntxhov siab thiab hnav tsis kam, xws li lub tes tsho npab, saw, thiab lwm yam.
2) Lub zog qis ntawm cov hlau carburized carbon steel xws li 20Cr, 20Cr2MnVB, 20Mn2TiB, nws cov permeability thiab cov tub ntxhais lub zog tseem siab dua carbon carburized carbon steel, tuaj yeem siv hauv kev tsim cov tshuab feem ntau tseem ceeb carburized qhov chaw, xws li tsheb, tsheb laij teb hauv lub iav , piston tus pin, thiab lwm yam.
3) Hauv cov alloy carburized carbon steel, xws li 20Cr2Ni4, 18Cr2N4W, 15Si3MoWV, vim nws lub zog loj thiab lub zog loj thiab lub siab tawv, feem ntau yog siv los tsim cov ntu loj, hnyav, cov kabmob thaj chaw, xws li cov khoom siv roj cav, cov ncej thiab li ntawd.
Kev sib xyaw carburizing, kua carburizing, roj carburizing - carburizing kub yog 900--950 ℃, txheej txheej W (carbon) yog 0.8-- 1.2%, txheej qhov tob yog 0.5--2.0mm.
Kev kho tshav kub tom qab carburizing - carburizing workpiece yuav tsum tau muab suav hais tias yog cov khoom siv sib xyaw nrog qhov sib txawv loj ntawm cov nplaim thiab cov ntsiab lus hauv nruab nrab. Carburizing tsuas yog tuaj yeem hloov cov pa roj carbon ntau ntawm cov haujlwm ntawm lub ntsej muag, thaum qhov kawg ua kom lub zog ntawm cov npoo thiab cov tub ntxhais yuav tsum ua tiav los ntawm kev kho kom sov. Tom qab carburizing lub workpiece yuav tsum tau quenched thiab tempered ntawm tsis kub. Lub hom phiaj ntawm kev ua kom cov pa roj carbon monoxide siab yog cov ua kom cov roj carbon martensite lossis cov pa roj carbon ntau ntawm cov roj ntsha ua kom lub ntsej muag thiab cov pob zeb carbide zoo rau saum npoo av. Kev ntsuas kub tsawg yog 150-200 ℃.
