1. Cov txheej txheem ntau lawm ntawm boiler raj
Kev tsim cov raj boiler feem ntau yog los ntawm cov kauj ruam hauv qab no: xaiv cov khoom siv, sib sau, vuam, kho cua sov, kuaj thiab kho qhov chaw.
1. Kev xaiv cov khoom siv
Kev xaiv cov khoom ntawm boiler raj yog thawj kauj ruam hauv kev tsim khoom thiab ib kauj ruam tseem ceeb heev. Cov ntaub ntawv zoo tshaj plaws tuaj yeem ua kom zoo thiab ua haujlwm ntawm cov raj boiler. Feem ntau, boiler raj yog ua los ntawm seamless steel kav los yog welded steel kav, feem ntau yog ua los ntawm cov pa roj carbon steel, alloy steel, thiab lwm yam. Thaum xaiv cov ntaub ntawv, yam xws li kev ua hauj lwm siab, kub, thiab nruab nrab ntawm boiler yuav tsum tau txiav txim siab los xyuas kom meej. tias cov ntaub ntawv xaiv tuaj yeem ua tau raws li qhov yuav tsum tau siv.
2. Kev tsim
Kev sib sau yog theem thib ob hauv kev tsim cov raj boiler. Cov txheej txheem tseem ceeb yog kub dov, kos duab txias, extrusion, thiab lwm yam. Ntawm lawv, kub dov yog txoj kev siv ntau tshaj plaws. Nws ua kom sov cov yeeb nkab steel mus rau qhov kub thiab txias thiab tom qab ntawd siv lub tshuab dov los yob nws kom cov yeeb nkab steel ncav cuag qhov xav tau thiab loj.
3. Vuam
Rau welded steel kav, vuam yog qhov txuas tseem ceeb hauv cov txheej txheem tsim khoom. Qhov zoo ntawm vuam ncaj qha cuam tshuam rau kev siv cov nyhuv thiab kev nyab xeeb ntawm boiler raj. Cov txheej txheem vuam feem ntau muaj xws li phau ntawv arc vuam, submerged arc vuam, TIG vuam, thiab lwm yam. Thaum lub sij hawm vuam, nws yog ib qho tsim nyog los xaiv cov khoom siv vuam tsim nyog thiab cov txheej txheem vuam kom ntseeg tau qhov zoo ntawm cov vuam.
4. Kev kho cua sov
Kev kho cua sov yog qhov txuas tseem ceeb hauv cov txheej txheem tsim khoom ntawm boiler raj. Los ntawm kev kho cua sov, qhov kev ntxhov siab nyob hauv cov yeeb nkab steel tuaj yeem raug tshem tawm thiab cov khoom siv kho tshuab thiab corrosion kuj ntawm cov yeeb nkab steel tuaj yeem txhim kho. Cov kev kho cua sov uas muaj xws li normalizing, annealing, quenching, thiab lwm yam.
5. Kev sim
Kev ntsuam xyuas yog qhov txuas tseem ceeb los xyuas kom meej qhov zoo ntawm boiler raj. Thaum lub sij hawm tsim cov txheej txheem, cov yeeb nkab steel yuav tsum tau nruj me ntsis soj ntsuam, nrog rau kev soj ntsuam zoo li qub, kev tshuaj xyuas qhov loj me, kev tshuaj xyuas cov cuab yeej cuab tam, kev tshuaj xyuas cov qauv metallographic, thiab lwm yam. Tsuas yog cov kav hlau steel uas dhau qhov kev tshuaj ntsuam tuaj yeem xa tuaj.
6. Kev kho deg
Kev kho deg yog cov kauj ruam kawg hauv kev tsim cov raj boiler. Los ntawm kev kho saum npoo, impurities xws li roj thiab xeb ntawm cov yeeb nkab steel tuaj yeem raug tshem tawm los txhim kho corrosion thiab kev pab cuam lub neej ntawm cov yeeb nkab steel. Cov kev kho saum npoo feem ntau muaj xws li sandblasting, pickling, passivation, thiab lwm yam.
