Khoom Description

Cored hlau yog cov cuab yeej nrov siv hauv ntau qhov kev lag luam los ntawm steelmaking mus rau metallurgy. Nws yog ua los ntawm cov hlau sheath uas muaj cov hmoov additives. Cov khoom siv tseem ceeb yog siv los ua kom paub cov khoom xav tau lossis alloy rau hauv cov hlau molten hauv kev tswj hwm. Cored hlau thev naus laus zis tau siv dav hauv xyoo tas los no vim nws lub peev xwm los xyuas kom meej qib siab dua thiab qhov tseeb hauv cov txheej txheem alloying.

Ib qho txiaj ntsig ntawm cored hlau yog tias nws tso cai rau kom yooj yim dua thiab zoo sib xws ntawm cov hlau. Kev siv cov cored hlau minimizes qhov poob ntawm alloying ntsiab thaum lub sij hawm tus txheej txheem. Nws kuj tseem txo qhov kev xav tau ntawm cov khoom siv kim kim uas yuav tsum tau siv ntau. Kev siv cov tshuab cored hlau tuaj yeem pab cov tuam txhab txuag nyiaj thiab txhim kho lawv cov khoom zoo.

Cored hlau tuaj yeem siv rau ntau yam kev siv xws li micro-alloying, desulfurization, thiab deoxidation. Cov cuab yeej no tau raug pov thawj tias muaj txiaj ntsig zoo hauv kev tsim cov hlau zoo, cam khwb cia hlau, thiab aluminium alloys.

Cored hlau yog ib qho yooj yim mus use thiab tuaj yeem muab ntxiv rau cov txheej txheem alloying uas twb muaj lawm yam tsis muaj kev hloov pauv loj. Tus nqi ntawm cored hlau feem ntau qis dua piv rau lwm txoj kev alloying, ua rau nws xaiv kev lag luam ntau dua rau kev lag luam.

Hauv cov ntsiab lus, cored hlau tshuab yog ib qho tshiab thiab siv tau zoo siv hauv kev tsim cov hlau zoo. Nws muaj ntau yam txiaj ntsig, suav nrog kev txuag nqi, txhim kho qhov tseeb, thiab siv tau yooj yim. Cored hlau yog qhov kev xaiv zoo rau ntau lub lag luam nrhiav los tsim cov hlau zoo thiab alloys.
