Deoxidizers nyob rau hauv Steelmaking: Ib Daim Ntawv Qhia Kom Paub Cov kab lus no muab cov ncauj lus kom ntxaws txog deoxidizers hauv steelmaking, tshawb txog lawv hom, kev ua haujlwm, thiab cuam tshuam rau cov hlau zoo. Peb mam li tshuaj xyuas cov tshuaj tiv thaiv kev cuam tshuam, sib tham txog ntau yam kev coj ua deoxidation, thiab tshuaj xyuas qhov zoo thiab qhov tsis zoo ntawm cov deoxidizers sib txawv. Kawm paub yuav ua li cas xaiv qhov zoo deoxidizer cuam tshuam rau cov khoom kawg ntawm cov hlau tsim.

Deoxidizers hauv Steelmaking: Phau Ntawv Qhia

Kev tsim cov hlau zoo yuav tsum tau ceev faj tswj xyuas cov ntsiab lus oxygen. Cov pa oxygen yaj hauv cov hlau molten tuaj yeem ua rau cov khoom tsis zoo xws li porosity, brittleness, thiab txo weldability. Qhov no yog qhov uas deoxidizers tuaj ua si. Cov neeg ua haujlwm no tau ntxiv rau cov hlau molten kom hnov ​​​​mob nrog cov pa oxygen, tsim cov khoom tsis yog xim hlau uas tuaj yeem tswj tau yooj yim dua lossis tshem tawm. Kev xaiv ntawm deoxidizer cuam tshuam rau cov khoom siv hlau kawg, ua rau cov txheej txheem xaiv tseem ceeb rau cov tuam txhab.

Hom Deoxidizers

Ntau hom deoxidizers yog siv hauv steelmaking, txhua tus muaj nws tus yam ntxwv thiab kev siv. Kev xaiv yog nyob ntawm yam xws li qib steel, cov khoom xav tau, thiab cov nqi txiav txim siab.

Aluminium

Aluminium yog lub zog thiab siv dav siv deoxidizer. Nws reacts muaj zog nrog oxygen, tsim aluminium oxide (Al₂O₃) suav nrog. Cov kev suav nrog no, txawm tias muaj kev cuam tshuam tsawg dua li cov pa oxygen, tseem tuaj yeem cuam tshuam cov khoom steel. Kev ua tau zoo ntawm txhuas ua deoxidizer nyob ntawm nws txoj kev sib ntxiv thiab cov txheej txheem steelmaking. Aluminium lub siab affinity rau oxygen tso cai rau deoxidation zoo txawm nyob rau hauv qis concentrations.

Silicon

Silicon yog lwm yam deoxidizer, feem ntau siv ua ke nrog txhuas. Nws reacts nrog oxygen los tsim silica (SiO₂) suav nrog. Silicon feem ntau tsis tshua muaj txiaj ntsig zoo dua li txhuas tab sis feem ntau nyiam rau nws cov nqi qis thiab muaj peev xwm los txhim kho steel fluidity. Kev sib xyaw ntawm silicon thiab txhuas feem ntau muab cov nyhuv deoxidation synergistic.

Manganese

Manganese ua raws li deoxidizer thiab tseem txhawb nqa cov khoom siv ntawm cov hlau. Nws reacts nrog oxygen los tsim manganese oxide (MnO) inclusions, uas feem ntau tsis tshua muaj teeb meem ntau tshaj li txhuas oxide los yog silica inclusions. Manganese feem ntau yog siv los ua cov deoxidizer thib ob, tshwj xeeb tshaj yog nyob rau hauv cov hlau tsis tshua muaj carbon. Qee zaum, Sab hauv Mongolia Xinxin Silicon Kev Lag Luam Co., Ltd tej zaum yuav muaj peev xwm muab kev daws teeb meem.

Rare Earth Elements

Tsis tshua muaj lub ntiaj teb cov ntsiab lus xws li cerium thiab lanthanum tau nce siv los ua deoxidizers hauv cov hlau tshwj xeeb. Lawv tsim zoo, dispersed inclusions uas tuaj yeem txhim kho kev huv huv thiab txhua yam khoom ntawm cov hlau. Cov ntsiab lus no tuaj yeem tshem tawm cov pa oxygen thiab sulfur zoo, ua rau kev txhim kho machinability thiab lwm yam khoom tsim nyog.

Kev Ua Haujlwm Deoxidation

Txoj kev deoxidizer ntxiv rau cov hlau molten cuam tshuam rau nws cov txiaj ntsig. Cov txheej txheem muaj xws li ladle deoxidation, txhaj tshuaj deoxidation, thiab nqus deoxidation. Txhua txoj kev muaj qhov zoo thiab qhov tsis zoo nyob ntawm daim ntawv thov tshwj xeeb.

Kev cuam tshuam rau cov khoom siv hlau

Kev xaiv ntawm deoxidizer thiab deoxidation xyaum ua tau cuam tshuam rau cov khoom kawg ntawm cov hlau. Kev deoxidation zoo ua rau txhim kho lub zog, ductility, weldability, thiab tag nrho zoo. Hloov pauv, deoxidation tsis txaus tuaj yeem ua rau muaj qhov tsis xws luag thiab txo kev ua haujlwm.

Kev tshawb fawb ntxiv rau hauv cov qib steel tshwj xeeb thiab lawv cov kev cuam tshuam nrog sib txawv cov deoxidizers pom zoo kom nkag siab tob txog cov txheej txheem nyuaj no. Kev sab laj cov peev txheej los ntawm cov koom haum muaj koob npe metallurgical thiab cov tuam txhab hlau yog qhov tseem ceeb rau kev txiav txim siab paub txog kev coj ua deoxidation.
