Martensitic Hlauyog cov khoom siv hlau loj tshwj xeeb, thiab nws cov txheej txheem tsim khoom muaj qhov tseem ceeb ntawm nws qhov kev ua tau zoo thiab daim ntawv thov. Los ntawm cov txheej txheem tswj cov txheej txheem thiab kev kho, cov ntaub ntawv hlau tuaj yeem hloov mus rau cov qauv hlau nrog Martensitic qauv, uas muab nws tshwj xeeb cov neeg kho tshuab thiab kav ntev. Kab lus no yuav tshawb txog cov txheej txheem tsim khoom ntawm martensitic steel los pab cov nyeem muaj kev nkag siab tob thiab cov yam ntxwv ntawm cov khoom no.
1. Melting
Cov chaw tsim khoom ntawm Martensitic Steel feem ntau pib nrog melting. Fais arc rauv lossis induction rauv taws tuaj yeem siv rau yaj npua hlau, seem steel thiab lwm cov khoom siv ua ke ua ke. Qhov txheej txheem melting yuav tsum tau tswj qhov kub thiab kev sib sau ua kom ntseeg tau qhov zoo ntawm cov khoom kawg.
2. Cawv
Cov hlau Molten yuav raug pov rau hauv kev noj lossis txuas ntxiv ua pov tseg. Ingots yog loj cam khwb cia hlau thaiv, thaum nruam nroo byting yog ntev billets. Kev Ingots yog loj cam khwb cia hlau thaiv, feem ntau hnyav hnyav rau ob peb tons. Ingots feem ntau cylindrical lossis duab plaub. Nruam casting billets yog ntev billets, feem ntau yog ntau metres ntev. Nruam casting billets feem ntau yog square lossis duab plaub.
3. Dov
Cov hlau sib xyaw lossis txuas ntxiv ua ke billet yuav muab dov rau hauv cov duab uas xav tau thiab loj. Cov txheej txheem dov tau muab faib ua ob hom: kub dov thiab dov tawm. Kub Rolling yog ib tug txheej txheem dov nqa tawm ntawm qhov kub siab, feem ntau nruab nrab 900-1200 degree. Kub Rolling muaj peev xwm yob hlau rau hauv ntau yam duab, xws li cov phiaj, strips, tuav thiab xaim. Whereas lub colding txias yog ib tug txheej txheem dov tawm ntawm chav tsev kub. Colding txias tuaj yeem txhim kho saum npoo ua tiav thiab qhov tseeb ntawm cov hlau, tab sis nws tseem yuav txo lub zog thiab tawv ntawm cov hlau.
4. Annealing
Annealing yog ib txheej txheem kho cua sov siv los soften steel thiab txhim kho nws cov khoom lag luam. Qhov kev siv anealing yog nqa tawm ntawm qhov kub thiab txias thiab tom qab ntawd txias maj mam. Qhov kev kub ntxhov yog feem ntau ntawm 600-700 degree, thiab lub sijhawm anealing nyob ntawm cov tuab thiab muaj pes tsawg leeg ntawm cov hlau.
5. Quenching
Quenching yog ib txheej txheem kho cua sov siv los ua kom lub zog thiab hardness ntawm cov hlau. Lub quenching txheej txheem yog nqa tawm ntawm qhov kub thiab txias thiab tom qab ntawd txias sai, feem ntau yog siv dej lossis roj. Lub quenching kub feem ntau yog nruab nrab 800-1000 degree, thiab quenching nruab nrab tuaj yeem yog dej, roj lossis lwm yam kua.
Tempering yog txheej txheem kho cua sov siv los txo cov brittleness ntawm cov hlau thiab txhim kho nws cov tawv. Tempering yog txheej txheem tom qab quenching, uas cov hlau yog rhuab rau qhov kub thiab txias dua thiab tom qab ntawd txias maj mam. Tempering kub feem ntau nruab nrab ntawm 200-400 degree, thiab lub sij hawm tempering nyob ntawm cov tuab thiab muaj pes tsawg leeg ntawm cov hlau.
7. Xov
Xov yog cov txheej txheem kawg tau siv los tshem tawm qhov tsis xws luag saum npoo av thiab txhim kho cov tsos ntawm hlau. XOV XWM KOOM tuaj yeem suav nrog sib tsoo, polishing lossis lwm cov txheej txheem.
Cov txheej txheem tsim khoom ntawmMartensitic Hlauyog cov txheej txheem ncaj qha thiab muaj cov txheej txheem. Txog ntawm kev tswj hwm ntau yam thiab ua cov kev pabcuam, los ntawm cov txheej txheem cua sov thiab cov khoom siv hlau tuaj yeem tau txais cov qauv kev sib tw zoo nkauj. Cov qauv no muab MARTENDITIC steel siab hardness, zoo heev lub zog thiab hnav tsis kam, ua rau nws dav siv nyob rau hauv lub tshuab txua.
