Cov txheej txheem tsim khoom thiab cov ntawv thov pob zeb ntawm JFE - EH 450 Steel
JFE - EH 450 Steel tau tshwm sim los ua cov khoom tseem ceeb hauv ntau qhov kev lag luam, ntaus nqi rau nws cov khoom zoo thiab kev ua tau zoo. Kev nkag siab txog nws cov txheej txheem tsim khoom thiab tshawb nrhiav cov ntaub ntawv thov tshwj xeeb yog qhov tseem ceeb kom txaus siab rau nws tus nqi thiab qhov tseem ceeb.
Cov txheej txheem tsim khoom ntawm JFE - EH 450 Steel yog kev ua haujlwm nyuaj thiab kev ua haujlwm zoo uas muaj ntau theem. Nws pib nrog kev ua tib zoo xaiv cov ntaub ntawv raw, nrog rau cov hlau zoo, coke, thiab lwm yam alloying ntsiab. Cov ntaub ntawv nyoos no yog qhov sib npaug kom ua tiav qhov xav tau tshuaj muaj pes tsawg leeg ntawm cov hlau.
Thawj kauj ruam yog cov txheej txheem smelting, qhov twg cov ntaub ntawv raw yog rhuab mus rau qhov kub siab heev nyob rau hauv lub qhov cub tawg kom tsim cov hlau molten. Cov hlau molten no ces xa mus rau lub converter lossis hluav taws xob arc rauv rau kev kho kom zoo ntxiv thiab kho cov tshuaj muaj pes tsawg leeg.
Tom qab ua tiav qhov xav tau muaj pes tsawg leeg, cov hlau molten yog cam khwb cia rau hauv slabs lossis billets. Cov txheej txheem casting yog ua tib zoo tswj xyuas kom muaj ib qho microstructure zoo ib yam thiab txo qhov tsis xws luag. Tom qab ntawd, cov slabs los yog billets undergo kub dov, qhov twg lawv tau dhau los ntawm ib tug series ntawm rollers ntawm kub kub kom txo lawv cov thickness thiab txhim kho cov neeg kho tshuab zog.
Txhawm rau txhim kho cov khoom ntawm JFE - EH 450 Steel, cov txheej txheem kho cua sov xws li quenching thiab tempering yuav raug ua haujlwm. Cov kev kho no hloov kho cov microstructure ntawm cov hlau, uas ua rau muaj kev txhim kho hardness, toughness, thiab hnav tsis kam.
Tam sim no, cia peb tig mus rau cov ntaub ntawv tshwj xeeb ntawm JFE - EH 450 Steel. Ib daim ntawv thov tseem ceeb yog hauv kev lag luam mining. Cov cuab yeej siv mining hnyav, xws li cov thoob excavator thiab crusher liners, feem ntau siv cov hlau no vim nws zoo heev hnav tsis kam thiab lub zog. Cov kev ua haujlwm hnyav hauv cov mines xav tau cov ntaub ntawv uas tuaj yeem tiv taus cov khoom siv thiab cov kev cuam tshuam siab, thiab JFE - EH 450 Steel ua pov thawj tias yog qhov kev xaiv zoo tshaj plaws.
