Nws yog qhov zoo li feem ntau ntawm cov neeg tsis paub txog qhov muaj nyob ntawm cov tub ntxhais qhwv cov xov hlau, vim tias lawv tsis yog ib qho zoo ntawm lub neej txhua hnub. Cov xov hlau no yog tsim los siv ib txoj hlua ntawm cov hlau uas yog qhwv hauv ib lub sawb ntawm cov hmoov hlau alloy. Lawv tuaj yeem muab faib ua ntau pawg raws li cov hmoov txhuas siv, suav nrog silicon calcium, silicon manganese calcium, silicon calcium barium, barium aluminium, aluminium calcium, calcium hlau, thiab calcium ntshiab. Cov windings ntawm cov xov hlau no zoo ib yam li cov coils, piv rau cov xov hlau uas siv hauv kev lag luam textile.
Nws raug pom zoo tias cov tub ntxhais qhwv cov hlau yuav tsum tau siv rau hauv qhov tsim nyog kom ua tau zoo deoxidation efficiency thiab txhim kho steel zoo. Nws yuav tsum tau muab sau tseg tias, nyob rau hauv txoj kab nrog kev txhim kho tsis ntev los no, hom core-wrapped hlau kuj ua ntau haiv neeg. Cov neeg siv muaj peev xwm xaiv thiab siv ntau hom cored hlau raws li lawv cov kev xav tau tshwj xeeb. Txhawm rau kom ua tiav cov txiaj ntsig zoo thaum siv cov hlau cored, nws yog qhov tseem ceeb kom nkag siab tias yuav siv nws li cas kom raug.
Ua ntej, nws yog ib qho tseem ceeb uas yuav tsum tau kho qhov ceev ntawm kev pub mis kom tsim nyog.
Qhov nqus ntawm calcium yog cuam tshuam los ntawm kev pub mis ceev. Yog tias nws ceev dhau lossis qeeb dhau, qhov nqus nqus yuav raug txo. Thaum cov core-cored hlau tau mus txog qhov tob, nws yuav pib yaj. Nws yog ib qho tseem ceeb los xyuas kom meej tias qhov tob tso cai rau cov calcium molten kom tawg tau zoo. Lub siab zoo li qub ntawm cov hlau molten ua rau nws tau noj tag nrho ua ntej nce mus rau qhov siab ntawm cov hlau molten. Los ntawm kev tswj hwm tus nqi noj kom tsim nyog, nws tuaj yeem txhim kho calcium rov qab. Yog tias qhov nrawm nrawm dhau, cov hlau yuav nyob hauv zos tsim los ntawm ntau cov calcium vapor uas tshwm sim los ntawm cov kua agitation, nrog rau cov calcium ntau ntawm vapor ncaj qha volatilised rau saum huab cua. Qhov no ua rau txo qis cov txiaj ntsig vim tias calcium vapors tau lig dhau los ua kom yaj thiab ntab hauv qhov ntau. Hloov pauv, yog tias qhov nrawm nrawm dhau, cov hlau cored yuav tsis pub tob txaus thiab yuav tsis yaj tag. Qhov no ua rau cov khoom ntab mus rau qib ntawm cov hlau molten, uas ua rau kev khib nyiab.
Qhov thib ob, qhov kev xaiv kom raug ntawm txoj haujlwm pub mis yog qhov tseem ceeb.
Txoj hauj lwm pub ntawm cored hlau kuj muaj feem cuam tshuam rau calcium rov qab. Cov ntsiab lus pub ntawm cov khoom siv calcium hlau yuav tsum raug xaiv nyob rau hauv nruab nrab ntawm qhov qis qis ntawm cov hlau molten, thiab kom deb li deb ntawm lub nplhaib ci ntawm argon tshuab, txhawm rau pab txhawb kev hloov pauv ntawm Ca rau hauv lub xeev gaseous lossis kua. . Nyob rau hauv qhov kev txiav txim ntawm downward flow, lub sij hawm nyob ntawm cored hlau nyob rau hauv molten steel yog ntev, kom ntseeg tau tiav nqus los ntawm molten hlau.
