Tshwj xeeb steelmaking nyob rau hauv lub European Union ua hauj lwm nyob rau hauv ib co ntawm lub ntiaj teb no txoj kev nruj tshaj plaws metallurgical qauv, tsav los ntawm siab -kawg tsheb, aerospace, thiab tauj dua tshiab zog engineering specifications. Hauv kev tsim cov hlau huv, cov cuab yeej hlau, thiab cov kabmob alloys, txo cov tshuaj lom neeg muaj pes tsawg leeg sib txawv thaum lub sij hawm metallurgy theem nrab yog qhov tseem ceeb. Kev hloov pauv hauv cov ntsiab lus tseem ceeb ua rau ncaj qha rau cov khoom siv kho tshuab tsis tuaj yeem, nce qhov kev tsis lees paub thaum tsis yog -kev kuaj kev puas tsuaj (NDT), thiab cov lus teb tsis sib xws rau kev kho cua sov hauv qab.

Txhawm rau tshem tawm cov kev hloov pauv no, European ladle metallurgy rauv (LMF) thiab lub tshuab nqus tsev degassing (VD/RH) cov neeg ua haujlwm tau hloov cov tsoos bulk alloy dumping nrog siab -kev kho metallurgy. Siv cov khoom sib xyaw tshwj xeeb ntawm cov khoom siv sib xyaw ua ke tso cai rau cov mills los qhia cov ntsiab lus ncaj qha rau hauv qhov sib sib zog nqus, siab - qhov chaw siab ntawm cov yaj. Qhov no txoj hauv kev yooj yim bypasses oxidizing slag txheej, sib npaug cov kab sib piv, thiab txhim kho cov khoom sib xws. Daim ntawv tshaj tawm kev lag luam no qhia txog cov ntsiab lus ntawm cov txheej txheem, kev tsim cov chemistry, thiab daim ntawv thov cov txheej txheem uas yuav tsum tau tswj cov molten chemistry variations, qhia tias yuav koom tes nrog lub ntiaj teb muaj ntawv pov thawj.cored hlau tsumnyiamZhenAntxhawb ntau lawm stability.

FAQ

 

Q1: Dab tsi ua rau molten steel muaj qhov sib txawv thaum lub sij hawm tshwj xeeb steel refining?

 

A: Molten steel muaj pes tsawg leeg variation feem ntau yog tshwm sim los ntawm qhov tsis sib xws ntawm oxidizing furnace slags, unpredictable alloy poob thaum lub ntiajteb txawj nqus ntau dumping, thiab variable re- oxidation los ntawm ambient huab cua. Tsis tas li ntawd, qhov tsis sib xws ntawm qhov kub thiab txias tsis sib haum thiab qhov tsis sib haum ntawm cov kinetics nyob rau hauv lub qhov cub hluav taws xob tuaj yeem tsim cov tshuaj stratification hauv zos, tiv thaiv kev sib faib ntawm micro- alloys thoob plaws hauv lub ntim ntim.

 

Q2: Yuav ua li cas cored hlau txhaj tshuaj pab txhim kho molten steel muaj pes tsawg leeg tswj?

 

A: Siv tus kws tshaj lijladle hlau feeding systemtso cai rau cov tswv lag luam txhawm rau txhaj cov lej ntawm cov ntsiab lus alloying ncaj qha mus rau thaj tsam qis ntawm lub ladle. Kev tiv thaiv steel sheath tiv thaiv cov khoom siv tseem ceeb los ntawm kev ua haujlwm ntxov ntxov nrog cov slag lossis huab cua. Qhov kev xa tawm lub hom phiaj no ua tiav cov txiaj ntsig zoo, muaj txiaj ntsig zoo ntawm cov txiaj ntsig rov qab los, ua rau cov pab pawg metallurgy ua kom raug micro- hloov kho thiab ntaus cov phiaj xwm nruj.

 

Q3: Vim li cas cov hlau zoo sib xws yog qhov tseem ceeb rau steel refining stability?

 

A: Nyob rau hauv siab - ntim cov khw tshwj xeeb steel, cov qauv ntsuas kev siv tshuab siv tau los ntawm cov khoom siv raw khoom nruj. Yog hais tias cov linear ceev los yog tshuaj sib piv ntawm ib yam khoom zoo liFeSi cored hlauNws txawv raws li nws qhov ntev, qhov tshwm sim ntawm cov ntsiab lus ntxiv yuav sib txawv ntawm cov qauv kev kwv yees. Qhov kev hloov pauv no ua rau kev hloov pauv tshuaj lom neeg tsis tau xav txog, yuav tsum tau siv sijhawm - siv rov ua dua - sim, txuas ntxiv lub sijhawm ua kom zoo dua qub, thiab nce nqi ntau lawm.

 

Q4: Yuav ua li cas steel mills ntsuam xyuas cored hlau zoo rau alloy ntxiv raug?

 

A: Steel mills ntsuas qhov zoo los ntawm kev sib xyaw ua ke ntawm lub cev thiab tshuaj ntsuam xyuas. Cov kws tshaj lij hauv chav kuaj txiav hla- cov qauv coj los ntawm cov xaim xaim los xyuas kom meej tag nrho cov kab tawm qhov hnyav, kos lub tsho steel tuab, thiab ntsuas cov hmoov ntim sab hauv. Cov hmoov tseem ceeb yog tshuaj xyuas los ntawm cov txheej txheem spectrometry meej kom ntseeg tau tias nws cov tshuaj profile sib phim lub hom phiajChemical Composition Specificationthiab tsis muaj dej noo.

 

Q5: Puas tuaj yeem ruaj khov cored hlau kev ua tau zoo txo ​​cov khoom rov qab hloov pauv hauv steelmaking?

 

A: Yog, kev xa khoom los ntawm tus tsimcored hlau tsumnyiamZhenAndramatically txo elemental rov qab hloov pauv. Delivering a completely uniform core filler and a tightly sealed lock-seam structure ensures the material dissolves at an identical depth in every heat, stabilizing elemental recovery yields and helping mills maintain high process capability indexes ($C_{pk}$).

 

Q6: Dab tsi cored hlau specifications cuam tshuam rau alloy rov qab efficiency thaum refining?

 

A: Cov ntsiab lus tseem ceeb suav nrog qhov sib xws ntawm txoj kab uas hla sab nraud, lub thickness ntawm lub tsho sab nrauv steel, cov tub ntxhais filling piv, thiab cov ntsiab lus noo noo ntawm cov hmoov. Lub thickness ntawm steel sawb yog tshwj xeeb tshaj yog ib qho tseem ceeb, raws li nws dictates lub sij hawm ciaj sia taus nyob rau hauv lub kub steel da dej thiab txiav txim seb cov tub ntxhais cov ntaub ntawv melts ntawm qhov zoo tshaj plaws qhov tob rau siab tshaj plaws dissolution thiab rov qab.

 

Q7: Ua li cas cored hlau zoo cuam tshuam qhov kawg steel huv thiab sib xws?

 

A: High-cov khoom siv tau zoo- xws li ntawv pov thawjcalcium hlau rau steelmaking- xyuas kom meej kev hloov pauv ntawm cov tawv tawv, nkig alumina pawg rau hauv qis - melting - taw tes kua calcium aluminates. Qhov kev hloov pauv niaj hnub no tso cai rau cov khoom tsis yog-cov khoom siv hlau sib xyaw kom ntab tawm mus rau hauv cov txheej slag, txo qis sab hauv micro- tsis xws luag thiab ua kom cov microstructure huv huv thiab qaug zog tiv thaiv thoob plaws txhua qhov ntau lawm.

 

Q8: Cov kev tswj xyuas zoo li cas yog siv los ua kom ruaj khov cored hlau ua haujlwm?

 

A: Cov tuam txhab hwm zoo siv txuas ntxiv ntawm - kab laser txoj kab uas hla taug qab, automated strip tension monitors, thiab hluav taws xob hmoov noj cov nplais thaum tsim khoom. Txhua pawg tsim khoom tau dhau mus nruj ua ntej- xa khoom kuaj kuaj thiab tau ntim rau hauv hnyav-lub luag haujlwm, noo noo- thaivTxheem Ntimkom ntseeg tau tias cov khoom tuaj txog dawb los ntawm kev sib kis thiab npaj rau kev them hluav taws xob ncaj qha.
