1. SMELTING thev naus laus zis
High-huv steel smelting:Hauv kev tsim cov gb teeb ntsia hlau, High-huv steel smatting yog qhov tseem ceeb pib txuas. Los ntawm kev kho mob ua ntej ntawm Molten hlau, cov teeb meem Sulfur hauv cov kab mob ntawm cov nqaj hlau tuaj yeem raug txo kom zoo, thiab kev sib tw ntawm cov nqaj hlau tuaj yeem hloov kho. Qhov txuas ntxiv lf Refining ntxiv cov kev suav nrog hauv Molten hlau, thiab nteg lub hauv paus rau cov kev sib tw tom qab ntawm kev sib tw loj.
Alloyter ntxiv thiab tswj:Raws li kev siv sib txawv sib txawv thiab kev ua tau zoo ntawm GB lub teeb ntsia, nws yog qhov tseem ceeb heev kom tsim nyog ntxiv cov alloy hais. Piv txwv li, hauv kev tsim cov kev sib tw ntawm qee cov kev tsheb ciav hlau uas yuav tsum tau coj kev coj tsis kam, manganese yuav ntxiv rau hauv tus nqi tsim nyog. Manganese tuaj yeem txhim kho lub zog thiab hnav tsis kam ntawm cov hlau, yog li cov ntsia muaj peev xwm tswj tau zoo hauv cov chaw sib npaug nquag. Rau cov ntsia nrog tshwj xeeb corrosion tsis kam lees yuav, tag nrho cov chromium thiab ncua cov kev pab cuam lub neej nyob rau hauv ib puag ncig muaj huab cua zoo li huab cua thiab seaside. In addition, advanced testing equipment is used to monitor the content of alloy elements in the molten steel in real time to ensure that the composition is accurate and in line with the standard.
2. Rolling txheej txheem
Cov txheej txheem kub dov:Kub Rolling yog cov txheej txheem tseem ceeb rau kev tsim GB lub teeb ntsia hlau. Lub smelted thiab ua kom zoo dua hlau billets yog rhuab rau ib qho ntsuas kub uas haum, feem ntau nyob ib ncig ntawm 1000 degree {1} degree, muab lawv zoo. Subsequently, the steel billets are gradually rolled into the required light rail shape and size through multiple passes of rolling on the hot rolling mill. Hauv cov txheej txheem no, dov lub zog, dov ceev thiab tus nqi ntawm kev txo qis hauv txhua kis yog tswj tau qhov tseeb ntawm cov ntsia. Piv txwv li, rau cov ciav hlau sib txawv xws li 8kg \/ m thiab 12kg \/ m, tus ntoo khaub ncaws nruj me ntsis kom ntseeg tau tias qhov sib txuas lus thiab kev teeb tsa teeb meem ntawm cov ntsia. Nyob rau tib lub sijhawm, ib txoj kev kub yob tau txhim kho cov qauv sab hauv, ua kom lawv cov nplej ua kom zoo nkauj, thiab txhim kho cov cuab yeej cuab tam ntawm cov ntsia hlau.
Semi-Nruam Rolling Txheej Txheem:Ib txhia Advanced GB lub teeb Kev muag khoom cov kab yuav khoom Semi-Nruam Rolling txheej txheem. Cov txheej txheem no ua ke qhov zoo ntawm kev siv tas mus li yob thiab sib qab yob, txhim kho cov khoom lag luam zoo thaum ua kom muaj kev ua haujlwm tau zoo. Nyob rau hauv lub semi-nruam cov txheej txheem txuas ntxiv, lub billet yog ntxhib-dov thiab tom qab ntawd nkag mus rau hauv cov txheej txheem rolling thaum lub sij hawm rolling kev sib txawv ntawm cov qauv tsheb ciav hlau.
3. Kev Kho Cua Sov Tshuab
Kev Kho Mob Li Qub:Kev ua ib txwm yog ib qho ntawm cov kev kho cua sov feem ntau rau GB lub teeb ntsia hlau. Cov tsaj rolls yog rhuab rau ib qho tsim nyog kub, feem ntau 30 degree {1}}} Cov qib siab tau hloov mus rau qee lub sijhawm, thiab tom qab ntawd txias rau saum huab cua. Los ntawm kev kho mob sab hauv, cov txheej txheem dov ntawm cov kev sib npaug, thiab cov kab sib txuas thiab tawv ncauj, kom tau raws li kev siv hauv qab kev cai ua haujlwm.
Quenching-tempering kev kho mob:Rau GB lub teeb ntsia hlau nrog lub zog siab dua thiab hnav cov kev xav tau tseem ceeb, kev ua kom nrawm dua. Ua ntej, txoj kev tsheb ciav hlau yog ua kom sov rau lub quenching kub, thiab tom qab ntawd txias kom tau lub martensic qauv, uas tau txhim kho lub hardness thiab lub zog ntawm txoj kev tsheb nqaj hlau. Tom qab ntawd, qhov kev kho tempering yog nqa tawm. Lub npau taws kub thiab muaj sij hawm raug muab kho raws li cov kev ua tau zoo los tshem tawm cov kev ntxhov siab, thiab ua kom cov kev sib tw ua tau zoo, yog li ntawd txoj kev sib tw ua tau zoo ntawm lub zog, Hardness, thiab tawv.
4. Nto Kho Tshuab
Kev Tiv Thaiv Xub:Txhawm rau tiv thaiv gb lub teeb ntsia hlau los ntawm xeb thiab corroding thaum lub sijhawm cia, kev thauj mus los thiab siv, qhov tseem ceeb ntawm xeb yog qhov tsim nyog. Cov hau kev suav sib xyaw suav nrog cov xim hlau xeb, thiab cov huab cua tsis zoo, thiab huab cua zoo, thiab maj mam txo tus nqi xeb ntawm txoj kev tsheb nqaj hlau. Ntxiv rau, kub-dip galvanizing cov txheej txheem tseem tuaj yeem siv los cuam tshuam cov tsheb ciav hlau hauv Mlott D cov txheej zinc rau nws saum npoo. Qhov kev tiv thaiv kev tiv thaiv zinc yog siv los tiv thaiv cov kev tsheb ciav hlau los ntawm kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv huab cua.
Kev Sib Tsoo Kho:Sib tsoo yog ib qho tseem ceeb txhais tau tias txhawm rau txhim kho qhov chaw zoo ntawm GB lub teeb ntsia hlau. Cov kev sib tsoo cov khoom sib tsoo yog siv kom ua kom zoo sib tsoo kom tshem tawm cov kev sib tw me me, cov nplai tawm, thiab tsis sib luag tshwm sim los ntawm cov txheej txheem dov. Qhov saum npoo ua tiav ntawm cov ntsia tom qab sib tsoo tom qab kev sib tsoo yog txhim kho kev sib cuag ntawm lub log thiab ntsia, txo cov kev sib txhuam, thiab kev nyab xeeb ntawm kev ua haujlwm hauv zej zog. Nyob rau hauv kev tsim cov teeb ntsia rau kev taug kev hauv qee qhov chaw zoo nkauj, tab sis kuj tseem ua kom muaj kev sib tsoo ntawm cov kev ua kom zoo nkauj tag nrho, muab cov neeg tuaj ncig ua si tag nrho, muab cov neeg tuaj ncig xyuas kev sib tw nrog kev caij tsheb zoo.
