A179 steel yeeb nkab yog cov khoom siv hlau tseem ceeb uas tau siv dav hauv kev tsim kho, kev tsim khoom, kev lag luam petrochemical, kev thauj mus los thiab lwm yam haujlwm. Cov txheej txheem ntawm cov yeeb nkab steel muaj ntau qhov sib txuas, suav nrog kev xaiv cov khoom siv raw, smelting, dov, vuam, kho deg, thiab lwm yam.
Hauv qab no peb yuav qhia txog cov txheej txheem dav dav thiab cov kev sib txuas tseem ceeb ntawm cov yeeb nkab steel ntau lawm.
1. Raw khoom xaiv: Cov khoom siv raw ntawm cov kav hlau steel yog cov hlau steel, uas tuaj yeem ua tau kub dov, txias dov coils lossis steel yeeb nkab billets. Thaum xaiv cov khoom siv raw, nws yuav tsum xav txog kev siv thiab kev ua haujlwm ntawm cov yeeb nkab steel thiab xaiv cov hlau tsim nyog.
2. Smelting: Muab cov hlau xaiv rau hauv qhov cub rau smelting, thiab yaj cov hlau ntawm qhov kub thiab txias kom tig mus rau hauv lub xeev ua kua. Thaum lub sij hawm smelting txheej txheem, lub cub tawg kub thiab cua nyob rau hauv lub cub tawg yuav tsum tau tswj los xyuas kom meej qhov zoo ntawm cov hlau.
3. Rolling: Cov hlau molten yog tsim rau hauv cov yeeb nkab steel blanks los ntawm kev nruam casting lossis dov txheej txheem. Nruam casting yog txhaj cov hlau molten rau hauv lub tshuab nruam nruam thiab tau txais cov hlau tsis tu ncua los ntawm kev txias thiab khov. Rolling yog pouring molten steel rau hauv cov yeeb nkab steel pwm, thiab tom qab ntau dhau ntawm dov thiab txias, cov yeeb nkab steel tsis muaj.
4. Kev sib sau: Cov yeeb nkab steel tsis muaj qhov tshwj xeeb tsim rau hauv cov yeeb nkab steel uas yuav tsum tau ua los ntawm lub tshuab tsim. Muaj ntau txoj kev tsim, xws li kub dov, txias dov, txias kos duab, txias dabtsi yog khoov, thiab lwm yam. Cov txheej txheem sib txawv yuav cuam tshuam rau qhov tseeb thiab qhov zoo ntawm cov kav dej steel.
5. Vuam: Rau cov kav hlau uas yuav tsum tau welded, cov yeeb nkab steel blanks yog welded. Cov txheej txheem welding feem ntau suav nrog kev ua haujlwm vuam, arc vuam, vuam zaus vuam, thiab lwm yam. Tom qab vuam, tsis muaj kev puas tsuaj thiab kev kho cua sov ntawm cov vuam yuav tsum tau ua kom ntseeg tau qhov vuam zoo thiab tag nrho kev ua haujlwm ntawm cov yeeb nkab steel.
6. Kev kho deg: Kev kho deg yog ua ntawm cov yeeb nkab steel los txhim kho nws cov corrosion kuj thiab zoo nkauj. Cov txheej txheem kho saum npoo muaj xws li galvanizing, txau, polishing, thiab lwm yam.
7. Kev Tswj Xyuas Zoo: Kev tswj xyuas zoo yog qhov tseem ceeb heev thaum lub sij hawm tag nrho cov txheej txheem ntau lawm. Los ntawm kev tswj xyuas nruj, xws li kev soj ntsuam cov khoom siv raw, saib xyuas cov txheej txheem tsim khoom, thiab ua qhov kev sim tsis muaj kev puas tsuaj, peb xyuas kom meej tias cov kav dej steel zoo raws li tus qauv yuav tsum tau ua.
