Hlau hais txog cov khoom siv hlau nrog hlau ua lub ntsiab lus tseem ceeb, cov ntsiab lus carbon feem ntau qis dua 2.0% thiab lwm yam. Qhov txawv ntawm nws thiab hlau yog cov ntsiab lus carbon. Nws yuav tsum tau hais tias nws yog tawv thiab ruaj khov dua hlau. Txawm hais tias nws tsis yooj yim rau xeb, nws yog ib qho nyuaj rau lav tias nws yuav corroded. Yog hais tias nws yog corroded thiab tsis kho raws sij hawm, nws yuav yooj yim corroded. Poob lub functionality nws yuav tsum muaj.

Thaum lub seamless steel yeeb nkab yog xeb, cov txheej txheem kho li cas? Qee tus neeg yuav siv txoj hauv kev los ntxuav cov yeeb nkab stainless hlau. Thaum ntxuav, lub npoo ntawm cov hlau yuav tsum tau ntxuav nrog hnyav thiab emulsion ua ntej. Txoj kev no tsuas yog siv los ua ib qho kev pab cuam ntawm kev tiv thaiv corrosion thiab tsis tuaj yeem tshem tawm cov yeeb nkab steel hlau tiag tiag. nyhuv ntawm xeb. Peb kuj tseem tuaj yeem siv cov txhuam hlau, cov hlua hlau thiab lwm yam cuab yeej los tshem tawm cov xoob oxide nplai thiab xeb ntawm qhov chaw ua ntej ntxuav, tab sis yog tias peb tseem tsis tau siv kev tiv thaiv, nws yuav raug eroded dua.

Pickling kuj yog ib txoj hauv kev los tshem tawm xeb. Feem ntau, ob txoj kev siv tshuaj thiab electrolysis yog siv rau kev kho mob pickling, thiab tsuas yog cov tshuaj pickling yog siv rau cov kav dej los tiv thaiv corrosion. Txawm hais tias txoj kev no tuaj yeem ua tiav qee qhov kev huv huv, nws yooj yim ua rau muaj kuab paug rau ib puag ncig, yog li nws tsis pom zoo siv nws.

Siv dav hlau derusting, lub cev muaj zog siab tsav dav hlau tuaj yeem tig ntawm kev kub ceev, kom cov abrasives xws li steel grit, steel tua, hlau hlau ntu, thiab cov ntxhia pob zeb yog jetted rau saum npoo ntawm stainless hlau yeeb nkab nyob rau hauv qhov kev txiav txim ntawm centrifugal quab yuam. Tsis tsuas yog tuaj yeem xeb, oxides thiab av raug tshem tawm tag nrho, tab sis cov yeeb nkab steel kuj tuaj yeem ua tiav qhov xav tau kev ntxhib los mos nyob rau hauv qhov kev txiav txim ntawm kev ua phem thiab kev sib txhuam ntawm cov abrasive. Kev tshem tawm xeb yog ib txoj hauv kev zoo tshaj plaws rau kev tshem tawm xeb hauv cov kav dej los tiv thaiv corrosion. Ntawm lawv, ntau txoj kev xav ntawm lub cev tau siv, kev ua qias tuaj rau ib puag ncig me me, thiab kev tu kom huv si.
