Kev tswj cov chromium (CR)
Muaj nuj nqi thiab cov ntsiab lus ntau: Chromium, ib qho tseem ceeb tshaj tawm hauv 2 {{{{{{}} 1 stainless hlau, tuaj yeem txhim kho cov hlau corrosion. Hauv 201 nyuam stainless hlau, cov ntsiab lus chromium feem ntau yog 16. 0 - 18. 0%. Chromium cov ntaub ntawv ntom zaj duab xis ntawm chromium oxide (cr₂o₃) nyob rau saum npoo ntawm stainless hlau, uas tuaj yeem tiv thaiv kom tsis txhob muaj pa thiab noo noo los ntawm kev nce qib sab hauv ntawm cov hlau.
Txoj Kev Tswj Xyuas: Thaum lub sijhawm smelting, cov ntsiab lus chromium yog feem ntau tswj hwm los ntawm kev xam kom raug thiab ntxiv chromium - muaj kev sib tw sib txuas. Ua ntej, lub cub hluavtaws yuav tsum tau ntsuas kom ncaj. Piv txwv li, thaum smelting nyob rau hauv ib lub hluav taws xob arc, tus nqi tsim nyog ntawm ferrrochrome yog ntxiv raws li cov kev ntsuas batch. Cov ntsiab lus chromium ntawm ferriorome feem ntau yog siab, thiab cawv ntawm nws cov ntsiab lus txawv txav ntawm cov ntsiab lus chromium kawg yuav tsum raug xam. Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them rau oxidation poob ntawm chromium thaum lub sijhawm smelting. Ntau dhau smelting kub thiab ntev smelting sijhawm yuav ua rau chromium oxidation hlawv. Feem ntau hais lus, lub suab kub yaj yog tswj tau ntawm nruab nrab 1500 - 1600 degree, uas tuaj yeem txo qis cov roj chromium. Nyob rau hauv lub chaw ua kom zoo, cov ntsiab lus chromium tuaj yeem kuaj pom los ntawm kev tsom xam thiab lwm txoj kev, thiab zoo - tig mus raws li cov ntawv xeem.
Kev tswj hwm ntawm Nickel (NI)
Muaj nuj nqi thiab cov ntsiab lus ntau: Nickel tuaj yeem txhim kho kev nruj, ductility, thiab corrosion tsis kam ntawm stainless hlau. Lub tsib xee cov ntsiab lus hauv 201 stainless hlau yog qhov tsawg, feem ntau 3. 5 - 5. 5%. Nickel tuaj yeem nthuav cov Austenite theem cheeb tsam, ua rau stainless hlau kom muaj tus qauv Austenite zoo, yog li tau txais zoo dua cov kev ua tau zoo.
Txoj Kev Tswj Xyuas: Cov neeg ua haujlwm tswj hwm cov ntsiab lus tsib xee los ntawm kev ntxiv npib tsib - Iron Alloy lossis Nickel ntshiab. Thaum sib xyaw cov ntaub ntawv, lawv yuav tsum xam cov nyiaj ntxiv raws li lub hom phiaj Nickel cov ntsiab lus. Piv txwv li, cov ntsiab lus tsib xee ntawm npib tsib xee - hlau alloy tej zaum yuav nyob ib ncig {2}}%. Thaum xam, nws yuav tsum tau hnyav raws li nws cov ntsiab lus npib tsib xee thiab lwm yam impurities. Nyob rau tib lub sijhawm, kev sib tw ntawm Nickel faib sijhawm thaum lub sijhawm smelting yuav tsum tau txiav txim siab. Nyob rau hauv cov theem tom qab ntawm smelting, lub sijhawm stirring tau txuas ntxiv kom ntseeg tau tias cov neeg npib dawb paug yog cov khoom siv Molten. Tshuaj lom neeg kev tsom xam cov txheej txheem xws li lub kaum kev lossis atomic nqus cov ntsiab lus siv tau los kuaj cov ntsiab lus npib tsib xee nyob rau lub sijhawm.
Kev tswj ntawm Manganese (MN)
Muaj nuj nqi thiab cov ntsiab lus ntau: Manganese ua lub luag haujlwm tseem ceeb hauv cov qauv ruaj khov ntawm cov qauv Austenite thiab ib nrab hloov Nickel hauv 201 stainless hlau. Nws cov ntsiab lus yog tus muaj siab, feem ntau 5. 5 - 7. 5%. Manganese tuaj yeem sib txuas nrog cov leej faj los ua manganese sulfide (MNS), yog li txo lub zog ntawm cov hlau rau ib qho.
Txoj Kev Tswj Xyuas: Cov ntsiab lus manganese yog tswj los ntawm kev ntxiv ferromanganese alloy. Muaj ntau hom ferromanganese alloys, xws li High - carbon ferromanganese, nruab nrab - carbon ferromanganese, thiab qis - carbon frealanganese. Xaiv cov kev tsim nyog ferromanganese alloy raws li qhov yuav tsum tau rau cov ntsiab lus carbon ntawm cov khoom kawg hlau kawg. Thaum lub sij hawm smelting txheej txheem, them sai sai rau qhov rov qab tus nqi ntawm manganese, uas feem ntau nyob ib ncig ntawm {}}%. Qhov ntsuas kub smelting thiab sijhawm yuav cuam tshuam rau cov ntsiab lus manganese. Qhov ntau dhau ntawm qhov kub yuav ua rau muaj kev kub ntxhov nce ntau ntxiv. Thaum lub sij hawm smelting txheej txheem, cov ntsiab lus manganese tuaj yeem raug txheeb xyuas los ntawm kev coj ua tsis tu ncua, piv txwv li cov feeb, thiab tom qab ntawd tus nqi ntawm manganese - hlau alloy ntxiv tuaj yeem hloov kho raws li cov tshuaj ntsuam xyuas.
Tswj cov pa roj carbon (c)
Muaj nuj nqi thiab cov ntsiab lus ntau: Cov pa roj carbon yog ib qho ntxiv dag zog, tab sis nyob rau hauv stainless hlau, dhau cov ntsiab lus carbon yuav txo cov pob corrosion tsis kam ntawm cov hlau. Cov ntsiab lus carbon ntawm 2 {{0 1 stainless hlau feem ntau yog hauv qab 0.15%. Tus nqi ntawm cov pa roj carbon tuaj yeem txhim kho lub zog ntawm cov hlau, yog li chromium carbide (crrac₆) nrog cov ntsiab lus roj carbium (, nws yuav cuam tshuam cov ntsiab lus roj carbium (bromix thiab cuam tshuam rau corrosion tsis kam.
Txoj Kev Tswj Xyuas: Txhawm rau tswj cov ntsiab lus carbon, peb yuav tsum xub xaiv cov qes qis - cov pa taws yuav them, xws li cov roj carbon vauv. Thaum lub sij hawm smelting, ib qho txheej txheem dazidation haum yuav tsum tau saws, vim tias muaj cov pa roj carbon monoxes ua rau muaj cov pa roj carbon monoxide (CO) Piv txwv li, hauv ARC - cov cua sov ua kom muaj kev sib xyaw ua ke, yog li siv phom sij rau hauv Molygen cov ntsiab lus hauv Molyen Steel yog tswj hwm qhov ploj ntawm cov roj carbon. Tsis tas li ntawd, hauv cov theem ua kom zoo, nqus tsev decarburization thiab lwm yam kev ua tau los txo cov ntsiab lus carbon tau kom nws mus txog lub hom phiaj.
Kev tswj cov nitrogen (n)
Muaj nuj nqi thiab cov ntsiab lus ntau: Nitrogen tuaj yeem hloov lub luag haujlwm ntawm Nickel hauv 2 0 1}}}} 1 lub zog thiab corrosion tsis kam ntawm cov hlau. Nws cov ntsiab lus feem ntau hauv qab 0.25%. Nitrogen atoms tuaj yeem yaj nyob rau hauv Austenite los tsim cov kev daws teeb meem zoo thiab txhim kho kev ua yeeb yam ntawm cov hlau.
Txoj Kev Tswj Xyuas: Thaum lub sijhawm smelting, cov peev txheej ntawm nitrogen yog feem ntau yog cov cua thiab tus nqi them. Txhawm rau tswj cov nitrogen cov ntsiab lus, tus neeg sawv cev flux tuaj yeem siv tau los npog cov hlau molten ntawm Molten Steel thiab huab cua, yog li txo qhov nqus ntawm nitrogen. Nyob rau tib lub sijhawm, tus nqi tau qhuav los txo cov kev taw qhia ntawm nitrogen - muaj impurities nyob rau hauv tus nqi. Hauv qee cov txheej txheem SMELTING GENERTING, tswj - huab cua smelting kuj tseem siv tau, xws li smelting nyob rau ib qho chaw muaj txiaj ntsig los tswj hwm tus nqi ntawm cov hlau molten. Yog hais tias cov nitrogen cov ntsiab lus dhau lawm, cov txheej txheem tsis pub dhau xws li lub tshuab nqus tsev tuaj yeem siv los kho nws.
