Khoom Description
Seamless ntshiab calcium cored hlau yog cov hlau ua los ntawm high-purity hlau calcium uas yog cov tub ntxhais thiab qhwv hauv seamless hlau sheath los ntawm cov txheej txheem tshwj xeeb. Lub purity ntawm hlau calcium nyob rau hauv cov tub ntxhais yog siab, uas muaj peev xwm ua kom cov hauj lwm zoo thiab stability nyob rau hauv cov txheej txheem metallurgical. Lub seamless tsim ntawm cov tawv nqaij sab nrauv tiv thaiv oxidation thiab kev ua qias tuaj ntawm cov tub ntxhais hlau calcium thaum thauj thiab siv. Los ntawm cov hlau feeder thiab lwm yam khoom siv, seamless ntshiab calcium-cored hlau tuaj yeem raug muab tso rau hauv, qhov sib ntxiv tuaj yeem tswj tau, thiab cov nyhuv metallurgical tuaj yeem txhim kho.
Nyob rau hauv cov txheej txheem ntawm steelmaking, seamless ntshiab calcium-cored hlau yog siv los ua deoxidizer thiab desulfurizer, uas tuaj yeem txo cov pa oxygen thiab sulfur cov ntsiab lus hauv cov hlau molten thiab txhim kho cov purity thiab zoo ntawm cov hlau molten. Nyob rau tib lub sijhawm, nws tuaj yeem cuam tshuam nrog lwm cov ntsiab lus hauv molten steel los tsim cov tebchaw muaj txiaj ntsig zoo rau cov khoom hlau. Nyob rau hauv cov txheej txheem casting, seamless ntshiab calcium cored hlau yuav siv tau rau inoculation kev kho mob ntawm castings, kev txhim kho lub microstructure ntawm castings thiab txhim kho lawv txhua yam khoom thiab tawg kuj. Tsis tas li ntawd, nws tseem tuaj yeem siv los kho cov tshuaj muaj pes tsawg leeg ntawm castings kom tau raws li cov kev xav tau tshwj xeeb.
Los ntawm kev tswj tus nqi ntawm seamless ntshiab calcium cored hlau, cov tshuaj muaj pes tsawg leeg ntawm molten steel los yog molten hlau yuav zoo-tuned. Ntau dhau los yog tsawg dhau lawm yuav ua rau cov tshuaj muaj pes tsawg leeg sib txawv ntawm lub hom phiaj tus nqi, yog li nws yog ib qho tsim nyog los tswj cov nyiaj ntxiv raws li cov txheej txheem tshwj xeeb thiab cov hom phiaj tshuaj muaj pes tsawg leeg. Txoj kev uas muab seamless ntshiab calcium cored hlau kuj yuav cuam tshuam nws cov nyhuv ntawm regulating tshuaj muaj pes tsawg leeg. Txoj kev xa khoom feem ntau suav nrog kev kho cov hmoov txau, qhov chaw pub mis ntawm cored hlau, thiab qhov tob pub ntawm cov hlau los ntawm cov phom phom. Txoj kev xa khoom sib txawv yuav cuam tshuam rau kev faib tawm thiab cov tshuaj tiv thaiv ceev ntawm calcium hauv molten steel lossis molten hlau, yog li nws yuav tsum xaiv txoj kev xa khoom tsim nyog raws li qhov xwm txheej tiag tiag. Qee zaum, seamless calcium cored hlau yuav tsum tau siv ua ke nrog rau lwm yam additives kom zoo dua kho cov tshuaj muaj pes tsawg leeg. Piv txwv li, nyob rau hauv tus txheej txheem ntawm desulfurization, nws yuav tsum tau ntxiv desulfurizers xws li calcium thiab magnesium nyob rau tib lub sij hawm los txhim kho cov nyhuv desulfurization.
Seamless ntshiab calcium cored hlau yuav tsum tau muab cia rau hauv qhov chaw qhuav, cua thiab corrosive gas-dawb ib puag ncig kom tsis txhob muaj kev sib cuag nrog cov khoom ntub thiab oxidizing. Nyob rau hauv tus txheej txheem ntawm casting, qhov sib ntxiv thiab casting ceev yuav tsum tau nruj me ntsis tswj kom ntseeg tau tias calcium tuaj yeem sib npaug thiab ruaj khov ntxiv rau molten steel lossis molten hlau.
