Dab tsi yog peb yam tseem ceeb uas cuam tshuam rau qhov zoo ntawm cov yob yob?

Rolls yog cov cuab yeej tseem ceeb siv hauv kev ua hlau thiab cov txheej txheem dov, ua lub luag haujlwm tseem ceeb hauv qhov zoo ntawm cov khoom kawg. Muaj ntau yam tseem ceeb uas cuam tshuam rau qhov zoo ntawm cov yob yob, tab sis peb yam nram qab no tseem ceeb tshwj xeeb.

1. Kev xaiv cov khoom siv

Cov khoom ntawm cov dov zeb ncaj qha txiav txim siab nws cov khoom tseem ceeb xws li hnav tsis kam, lub zog, thiab corrosion kuj. Cov ntaub ntawv yob feem ntau suav nrog siab chromium cam khwb cia hlau, hlau alloy, thiab tungsten carbide. Thaum xaiv cov ntaub ntawv, nws yog ib qho tsim nyog yuav tau xav txog cov yam ntxwv thiab cov txheej txheem ntawm cov txheej txheem hlau. Piv txwv li, rau dov yob nyob rau hauv high-temperature ib puag ncig, nws yog ib qhov tsim nyog los xaiv cov hlau alloy nrog zoo heev tshav kub tsis kam thiab yuav tsum tau kev kho cua sov tsim nyog los txhim kho nws hardness thiab hnav tsis kam. Kev xaiv cov khoom siv tsis raug yuav ua rau cov menyuam puas tsuaj, lub neej luv luv, thiab txawm tias tsim khoom raug mob.

2. Txheej txheem kev tsim khoom

Kev tsim cov txheej txheem ntawm dov yob ncaj qha cuam tshuam rau qhov tseem ceeb xws li cov duab raug, qhov smoothness, thiab sab hauv microstructure. Cov txheej txheem tsim khoom suav nrog cov kauj ruam xws li casting, forging, mechanical processing, thiab kev kho cua sov. Ntawm lawv, casting yog lub hauv paus rau kev tsim cov chais, thiab cov txheej txheem casting tsim nyog tuaj yeem ua kom muaj qhov sib xws thiab qhov tsis zoo ntawm cov khoom siv rau cov menyuam. Forging thiab mechanical processing tuaj yeem txhim kho qhov tseeb thiab qhov zoo ntawm cov yob yob. Kev kho cua sov yog cov kauj ruam tseem ceeb kawg, uas tswj cov hardness, toughness, thiab sab hauv kev nyuaj siab faib ntawm dov zeb los ntawm kev tswj qhov kub thiab txias thiab lub sij hawm kom tau raws li qhov yuav tsum tau siv nyob rau hauv txawv kev ua hauj lwm tej yam kev mob.

3. Kev siv thiab tu

Txawm hais tias cov khoom siv zoo raug xaiv thiab cov txheej txheem tsim khoom siab heev tau txais, yog tias tsis siv thiab khaws cia kom zoo, qhov zoo ntawm cov dov zeb tseem yuav cuam tshuam. Ua ntej, txoj kev siv kom raug thiab cov qauv kev ua haujlwm yog qhov tseem ceeb. Piv txwv li, thaum lub sij hawm dov txheej txheem, nws yog ib qho tsim nyog los tswj qhov kub thiab siab ntawm cov chais kom tsis txhob hnav ntau dhau los yog deformation. Lub caij no, lub sij hawm lubrication thiab txias tuaj yeem ua tau zoo rau kev pab cuam lub neej ntawm lub tshuab dov. Qhov thib ob, kev tshuaj xyuas thiab kev saib xyuas ntawm cov rollers tsis tu ncua kuj tseem ceeb heev. Kev tshuaj xyuas qhov chaw ntawm lub tshuab dov tsis tu ncua rau cov kab nrib pleb, khawb, lossis qaug zog, thiab kho lossis hloov cov khoom puas hauv lub sijhawm tuaj yeem tswj tau qhov kev ua haujlwm zoo ntawm lub tshuab dov.

Hauv cov ntsiab lus, muaj ntau yam cuam tshuam rau qhov zoo ntawm cov yob yob, tab sis xaiv cov khoom siv, txheej txheem tsim, thiab kev saib xyuas yog peb yam tseem ceeb tshaj plaws. Tsuas yog los ntawm kev ua haujlwm zoo hauv cov ntsiab lus tseem ceeb no tuaj yeem ua kom peb lub neej ua haujlwm zoo thiab ua haujlwm ntev ntawm cov yob yob, thiab muab kev txhawb nqa ruaj khov thiab txhim khu kev qha rau cov txheej txheem hlau thiab cov txheej txheem dov.
