Khoom Taw qhia

d2 cuab yeej steel yog ntau yam high-carbon, high-chromium, cua-hardening cuab yeej hlau uas yog tus yam ntxwv los ntawm ib tug kuj siab attainable hardness thiab ntau, loj, chromium-nplua nuj alloy carbides nyob rau hauv lub microstructure. Cov carbides muab kev tiv thaiv zoo rau hnav los ntawm kev sib cuag nrog lwm cov hlau thiab cov khoom siv abrasive. Txawm hais tias lwm cov hlau uas muaj kev txhim kho toughness lossis txhim kho kev hnav kuj muaj, d2 cuab yeej steel puag ncig bar muab kev sib xyaw ua haujlwm zoo ntawm hnav tsis kam thiab toughness, cuab yeej kev ua tau zoo, nqi, thiab ntau yam khoom siv.

Sichuan Huitai tsim d2 cuab yeej steel puag ncig bar feem ntau tsim siv ob txoj kev smelting: EAF + LF + VD thiab EAF + LF + VD + ESR.
Rau cov txheej txheem LF + VD refining, ntxiv dag zog rau cov deoxidation thaum lub sij hawm LF rauv txo qis thiab ua kom lub tshuab nqus tsev degassing nyhuv ntawm VD rauv yog cov txheej txheem tseem ceeb ntsuas los txo cov ntsiab lus oxygen. Kev sib koom ua ke deoxidation yog saws nyob rau hauv LF rauv los tswj cov alkalinity ntawm cov slag dawb kom ntau dua los yog sib npaug rau 4 thiab lub tshuab nqus tsev kawm ntawv ntawm VD rauv kom ntau dua los yog sib npaug rau 67Pa. Piv nrog rau qhov nruab nrab cov pa oxygen hauv ib txwm tsim, cov ntsiab lus oxygen hauv D2 cov cuab yeej hlau tau txo qis los ntawm 50.88%.
