Cored hlau yog tsim rau steelmaking deoxidation, desulphurisation, tuaj yeem txhim kho kev ua haujlwm ntawm cov hlau, txhim kho cov yas ntawm cov hlau, cuam tshuam rau cov tawv nqaij thiab cov kua dej ntawm cov hlau, tab sis kuj muaj cov yam ntxwv ntawm kev nkag ncaj qha rau cov yaj hauv cov kua hlau, kev faib tawm thiab lwm yam. ntawm.
Nrog rau txoj kev loj hlob ntawm cov hlau alloy steel kev lag luam, high-zoo alloy steel, ib tug ntau yam ntawm cov hlau, kev nruam txhim kho ntawm lub cub tawg refining thev naus laus zis, pab txhawb txoj kev vam meej ntawm kev loj hlob ntawm cov khoom siv hlau. Txais siv hlau pub tshuab muaj kev ua tau zoo dua li cov hmoov txau thiab ncaj qha ntxiv ntawm alloying blocks.
Calcium silicate alloy cored hlau cored thev naus laus zis yog ib qho kev siv hluav taws xob ntxiv rau kev kho kom zoo nkauj, yog siv dav hauv kev cob qhia steel hlau niaj hnub siv tshuab. Alloy core refining siv nyob rau hauv steelmaking yuav purify hlau, hloov cov inclusions daim ntawv, txhim kho lub castability thiab mechanical zog ntawm steel, thiab yuav ho txhim kho cov yield ntawm ferroalloys, txo tus nqi ntawm steelmaking, lub economic nyhuv yog zoo kawg li. Kev pub kab tshuab siv dav siv los ua deoxidiser, desulphuriser, hloov daim ntawv ntawm kev suav nrog hauv cov hlau thiab txhim kho qhov zoo.
