Txheem rau tu cov kauj ruam ntawm seamless steel kav
1. Kev ntxuav ntawm seamless steel kav
Siv cov kuab tshuaj thiab emulsions los ntxuav cov kav dej hnav-resistant, hnav-resistant ceramic kav, cov kav dej ceramic, thiab cov kav dej ceramic, txhawm rau tshem tawm cov roj, roj, plua plav, lubricants, thiab cov organic zoo sib xws. Txawm li cas los xij, nws tsis tuaj yeem tshem tawm xeb, oxide daim tawv nqaij, vuam flux, thiab lwm yam ntawm cov hlau, yog li nws tsuas yog siv los ua ib qho kev pab cuam hauv kev tiv thaiv corrosion ntau lawm.
2. Cov cuab yeej xeb tshem tawm rau seamless steel kav
Feem ntau siv cov cuab yeej xws li hlau txhuam los txhuam qhov saum npoo ntawm cov hlau, nws tuaj yeem tshem tawm xoob lossis tsa cov tawv nqaij, xeb, vuam slag, thiab lwm yam. Cov cuab yeej siv tau tuaj yeem ua tiav Sa2 qib xeb tshem tawm, thaum cov cuab yeej hluav taws xob tuaj yeem ua tiav Sa3 qib xeb tshem tawm. Yog hais tias cov hlau nto yog ruaj khov nrog oxide nplai, qhov kev tshem tawm xeb ntawm cov cuab yeej tsis zoo, thiab qhov tob tob uas yuav tsum tau ua los tiv thaiv corrosion tsis tuaj yeem ua tiav.
3. Pickling ntawm seamless steel kav
Feem ntau, ob txoj kev, tshuaj thiab electrolytic, yog siv rau kev kho cov kua qaub. Rau cov kav dej hnav-tiv taus, hnav-tiv taus cov kav dej ceramic, cov kav dej ceramic, thiab cov kav dej ceramic, tsuas yog cov tshuaj acid pickling yog siv los tiv thaiv corrosion, uas tuaj yeem tshem tawm oxide nplai, xeb, thiab cov txheej qub. Qee zaum, nws tuaj yeem siv ua ntej kho tom qab sandblasting thiab xeb tshem tawm. Txawm hais tias kev tu tshuaj lom neeg tuaj yeem ua tiav qee theem ntawm kev huv thiab roughness ntawm qhov chaw, nws cov kab thauj tog rau nkoj yog qhov ntiav thiab tuaj yeem ua rau muaj kuab paug ib puag ncig.
