1, Kev cuam tshuam ntawm alloying ntsiab
Lub luag haujlwm ntawm chromium keeb
Thaum cov ntsiab lus chromium nyob rau hauv cov hlau ncav cuag ib qho kev faib ua feem (xws li nyob ib ncig ntawm 1.2%), chromium reacts nrog oxygen nyob rau hauv lub corrosive nruab nrab los ua ib tug nyias oxide zaj duab xis nyob rau saum npoo ntawm cov hlau, uas yuav tiv thaiv tau ntxiv corrosion ntawm steel substrate. Cov yeeb yaj kiab oxide no ua haujlwm raws li cov txheej txheem kev sib cais, txo kev sib cuag ncaj qha ntawm cov yeeb nkab steel thiab qhov nruab nrab corrosive, yog li txhim kho corrosion kuj ntawm seamless steel yeeb nkab.
2, Qhov cuam tshuam ntawm kev kho deg
Multi-layer anti-corrosion xim kho
Hloov cov txheej txheem ib txheej los tiv thaiv xeb xim txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej ntxiv kev txhim kho kev ua tau zoo ntawm cov txheej txheem tiv thaiv corrosion thiab nws cov corrosion kuj, huab cua tsis kam thiab lwm yam ntxwv, zoo heev txhim kho corrosion kuj ntawm seamless steel kav.
Qhov cuam tshuam ntawm seamless tiv thaiv txheej
Zoo li 20 seamless steel kav, cov txheej txheem tiv thaiv seamless ntawm lawv qhov chaw tuaj yeem tiv thaiv kev cuam tshuam ntawm oxygen, dej, thiab lwm yam tshuaj, ua kom lub neej ntawm cov yeeb nkab steel, thiab ua kom nws muaj kev tiv thaiv corrosion zoo heev. Nws yog tsim rau kev tsim kho tej yaam num nyob rau hauv ntau yam tej yam kev mob, xws li marine engineering thiab chemical engineering.
3, Kev cuam tshuam ntawm steel yeeb nkab khoom nws tus kheej
Qhov sib txawv ntawm cov khoom sib txawv
Piv txwv li, qhov kev tiv thaiv corrosion ntawm Q355B seamless steel yeeb nkab yog qhov tsis zoo, thiab nws yooj yim rau xeb thiab tshuaj lom neeg corrosion; Tom qab tsim nyog los tiv thaiv corrosion (xws li galvanizing lossis chrome plating), seamless yeeb nkab No. 20 tuaj yeem muaj qhov zoo corrosion. Qhov no qhia tau hais tias seamless steel kav ntawm cov ntaub ntawv sib txawv muaj qhov sib txawv ntawm corrosion kuj, thiab cov yam ntxwv ntawm cov khoom nws tus kheej muaj feem cuam tshuam rau corrosion kuj.
4, Qhov cuam tshuam ntawm kev siv tshuab
Kev cuam tshuam ntawm cov txheej txheem vuam
Cov kev cai ntawm cov yam ntxwv vuam sib txawv nyob ntawm cov khoom, thiab cov khoom feem ntau qhia tias cov ntaub ntawv raw muaj cov yam ntxwv zoo heev. Kev tuav tsis raug ntawm cov txheej txheem vuam tuaj yeem cuam tshuam qhov corrosion kuj ntawm seamless steel kav. Piv txwv li, ntawm qhov chaw vuam, qhov kev ncaj ncees ntawm cov yeeb nkab steel nto yuav raug cuam tshuam los ntawm cov teeb meem zoo xws li porosity, slag suav nrog, thiab lwm yam tsis xws luag, yog li txo nws cov corrosion kuj. Yog tias cov qauv hlau ntawm lub vuam seam tsis sib haum nrog lub hauv paus hlau, nws kuj tuaj yeem ua rau muaj qhov sib txawv ntawm corrosion kuj.
Kev cuam tshuam ntawm polishing txheej txheem
Cov yam tseem ceeb cuam tshuam rau polishing yam ntxwv yog raws li nram no:
Qhov chaw tsis xws luag ntawm cov khoom siv raw, xws li khawb, cov pob dub, ntub dej, thiab lwm yam, tuaj yeem cuam tshuam rau corrosion tsis kam ntawm cov kav dej steel. Vim tias cov cheeb tsam tsis zoo no tuaj yeem dhau los ua qhov pib ntawm corrosion, nyob rau hauv ib puag ncig corrosive, qhov nruab nrab corrosive feem ntau yuav corrode steel yeeb nkab ntawm no.
Qhov teeb meem raw khoom ntawm cov kav dej loj-ntev seamless steel kav yog tias lub zog tsawg dhau, ua rau nws nyuaj rau polish (BQ tsis zoo), qhov nyuaj yog qhov tsawg dhau, thiab qhov saum npoo yog feem ntau ua rau txiv kab ntxwv tev thaum ncab, uas cuam tshuam. BQ cov yam ntxwv thiab tej zaum yuav cuam tshuam rau corrosion kuj ntawm cov yeeb nkab steel.
Tom qab kos duab sib sib zog nqus, cov pob dub thiab RI imitation DGING tseem yuav tshwm sim nyob rau hauv deformation imitation DGING, cuam tshuam rau cov yam ntxwv BQ thiab tejzaum nws tsis ncaj qha cuam tshuam rau corrosion kuj ntawm cov yeeb nkab steel.
