Lub nra hnyav suav
Ua ntej steelmaking, lub nra hnyav yuav tsum tau ua raws li lub hom phiaj ntawm AB EQ47 steel. Piv txwv li, rau cov pa roj carbon (C) cov ntsiab lus, cov ntsiab lus carbon nyob rau hauv cov ntaub ntawv raw xws li seem hlau thiab npua hlau yuav tsum raug coj mus rau hauv tus account, thiab cov ntaub ntawv ntawm carbon tuaj yeem pib tswj tau los ntawm kev sib xyaw cov ntaub ntawv raw. Yog tias koj xav tswj cov ntsiab lus carbon nyob rau hauv lub hom phiaj (piv txwv li, cov ntsiab lus siab tshaj plaws yog 0.20%), nws yog qhov yuav tsum tau ua kom raug xam qhov feem ntawm ntau yam khoom siv raw. Lub caij no, cov kev xam lav zoo sib xws yuav tsum tau ua rau cov ntsiab lus alloying xws li manganese (Mn) thiab silicon (Si). Piv txwv li, thaum lub hom phiaj cov ntsiab lus ntawm manganese yog siab tshaj plaws ntawm 1.70%, qhov ntxiv ntawm manganese yuav tsum tau txiav txim siab raws li cov ntsiab lus ntawm manganese nyob rau hauv ferromanganese alloys thiab lwm yam manganese-muaj raw cov ntaub ntawv.

Kev soj ntsuam thiab kev hloov kho thaum lub sij hawm steelmaking txheej txheem
Hloov steelmaking theem: Thaum lub tshuab tshuab hauv lub converter, qhov sib xyaw ntawm cov hlau molten yuav tsum tau saib xyuas hauv lub sijhawm. Piv txwv li, cov ntsiab lus cov ntsiab lus ntawm cov ntsiab lus xws li carbon thiab phosphorus nyob rau hauv cov hlau molten tuaj yeem tau txais los ntawm sublance nrhiav kom tau qhov system. Yog tias cov ntsiab lus carbon siab dhau lawm, cov ntsiab lus carbon tuaj yeem raug txo los ntawm kev ua kom lub sij hawm ua pa oxygen. Rau kev tshem tawm ntawm phosphorus, nws yog ib qho tsim nyog los xyuas kom meej cov slag tsim nyog thiab fluidity zoo kom phosphorus tuaj yeem oxidized thiab nkag mus rau hauv slag. Feem ntau hais lus, los ntawm kev ntxiv slag-ua cov ntaub ntawv xws li txiv qaub los kho cov slag muaj pes tsawg leeg thiab tswj cov slag hauv paus ntawm ib ncig ntawm 3 - 4, nws yog conducive rau tshem tawm phosphorus thiab txo nws cov ntsiab lus rau lub hom phiaj (qhov siab tshaj plaws yog 0.025%).
 

Tswj nyob rau hauv qhov nruam casting thiab cov txheej txheem tom ntej
Thaum lub sij hawm nruam casting txheej txheem, theem nrab oxidation thiab muaj pes tsawg leeg segregation ntawm molten hlau yuav tsum tau tiv thaiv. Los ntawm kev siv cov txheej txheem kev tiv thaiv casting, xws li siv cov twj tso kua mis submerged thiab pwm fluxes, kev sib cuag ntawm molten hlau thiab cua tuaj yeem raug txo kom tsis txhob oxidation ntawm alloying ntsiab. Piv txwv li, rau cov ntsiab lus uas nquag oxidation xws li txhuas (Al) (txawm hais tias nws tsis tau hais tias yog ib qho tseem ceeb alloying nyob rau hauv AB EQ47 steel, nws yuav muab ntxiv me me rau deoxidation thaum lub sij hawm steelmaking txheej txheem), tiv thaiv casting muaj peev xwm. zoo txo ​​nws cov oxidation thiab yog li xyuas kom cov hlau zoo. Tsis tas li ntawd, thaum lub sij hawm ua tom qab xws li dov, tus cwj pwm ntawm alloying ntsiab nyob rau hauv cov txheej txheem kub ua hauj lwm yuav tsum tau xav txog. Piv txwv li, qee cov ntsiab lus alloying yuav cuam tshuam rau qhov kub ntawm cov hlau recrystallization. Los ntawm kev tswj xyuas qhov kub thiab qhov txo qis, qhov kev ua kom muaj zog ntawm cov ntsiab lus alloying tuaj yeem ua tau zoo dua, thiab tib lub sijhawm, qhov tsis sib xws ntawm cov ntsiab lus alloying lossis kev ua haujlwm degradation tshwm sim los ntawm kev ua cov txheej txheem tuaj yeem zam tau.

 

 

 

Kev tshuaj xyuas zoo thiab kev tawm tswv yim
Nws yog ib qho tsim nyog yuav tsum tau ua kom tiav kev tshuaj ntsuam xyuas ntawm cov hlau tiav AB EQ47 tsis tu ncua. Cov txheej txheem tshawb nrhiav qib siab xws li kev tsom xam spectral tau txais los ntsuas cov ntsiab lus ntawm cov ntsiab lus alloying kom ntseeg tau tias lawv ua tau raws li cov qauv. Yog tias nws pom tias cov ntsiab lus ntawm cov ntsiab lus alloying tshaj qhov ntau, nws yog qhov yuav tsum tau taug qab cov txheej txheem steelmaking hauv lub sijhawm, nrhiav cov teeb meem, thiab kho cov txheej txheem tsis ua haujlwm. Piv txwv li, yog tias nws tau kuaj pom tias cov ntsiab lus ntawm manganese tshaj tus qauv, nws yuav tsum tau xyuas seb qhov sib ntxiv ntawm ferromanganese alloys yog xam tsis raug lossis puas muaj lwm yam uas ua rau muaj qhov txawv txav ntawm manganese cov ntsiab lus hauv cov txheej txheem steelmaking, xws li. Raws li kev tawg ntawm manganese nyob rau hauv lub qhov cub hauv ob sab phlu cov ntaub ntawv rau hauv cov hlau molten. Los ntawm kev kaw-voj tswj ntawm kev soj ntsuam zoo thiab kev tawm tswv yim, kev tswj cov ntsiab lus ntawm cov ntsiab lus alloying tuaj yeem ua kom zoo tsis tu ncua kom tau txais qhov kev ua tau zoo tshaj plaws.
