Alloy rolls yog siv nyob rau hauv roughing mills rau square / slab billets, loj seem steel billets, thiab rail beam mills; loj ntsug yob nyob rau hauv ob- yob roughing mills rau phaj thiab sawb hlau thiab nplais - tawg stands; thiab roughing mills rau seem steel, bar, thiab hlau qws mills.
Hauv cov ntawv thov no, alloy cam khwb cia hlau yob ua lub luag haujlwm tseem ceeb. Txhawm rau ua kom tau raws li qhov xav tau ntawm cov txheej txheem sib txawv, cov yob feem ntau yog tsim los ntawm kev sib xyaw ua ke thiab cov txheej txheem sib xyaw ua ke. Cov khoom siv hlau cam khwb cia hlau yog ua tib zoo xaiv, nrog nws cov ntsiab lus carbon thiab qhov sib txawv ntawm cov hlau alloying nruj me ntsis tswj raws li qhov yuav tsum tau muaj hardness.
Alloy cam khwb cia hlau cov ntaub ntawv muaj qib siab alloying ntsiab xws li chromium, molybdenum, thiab vanadium. Nrog rau kev nce hauv cov ntsiab lus alloy, cov qauv matrix hloov ntawm sorbite mus rau bainite lossis martensite. Cov kev hloov pauv no muab cov khoom siv siab -hardness thib ob carbides, nrog rau qhov hardness ntau ntawm HS 55-70, txhim kho cov khoom hnav tsis kam thiab muaj peev xwm tiv thaiv.
Kev ua tau zoo tshaj ntawm cov yob yob, nthuav tawm cov yam ntxwv zoo nyob rau hauv siab - lub zog thiab siab - hnav khaub ncaws, ua kom muaj kev ua haujlwm siab thiab ruaj khov ntawm lub tshuab dov thaum lub sijhawm ua haujlwm ntev -. Yog li ntawd, alloy cam khwb cia hlau yob nyob rau hauv ib qho tseem ceeb txoj hauj lwm nyob rau hauv niaj hnub steel kev lag luam thiab tau dhau los ua cov khoom nyiam rau cov khoom tseem ceeb xws li kev txhawb nqa yob thiab ua haujlwm yob.
