Kev kho cov npoo npoo
Pickling: Los ntawm pickling, cov oxide nplai thiab impurities nyob rau saum npoo ntawm alloy cov tuav tau muab tshem tawm cov xim hlau, thiab txhim kho cov corrosion tsis kam thiab cov tsos zoo.
Ci Kho: Cov hau kev xws li electrolytic polishing thiab cov neeg kho tshuab polishing yog siv los ua kom lub npoo ntawm cov kab hlau uas tau txais daim iav zoo li ci ntsa iab. Qhov no tsis tsuas yog txhim kho cov tsos zoo tab sis kuj txo cov npoo roughness thiab txo cov adsorption ntawm corrosive media.
Kev Kho Mob Passivation: Cov kab sib txuas tau muab tso tawm hauv cov kev daws teeb meem hla los tsim zaj duab xis passivation ntawm sab, txhim kho lub corrosion tsis kam ntawm alloy.
Cov txheej txheem raug
Kub Ua Haujlwm: Cov kub ua haujlwm kub ntau ntau yog feem ntau nruab rau 950-1150 degree. Forging, dov thiab lwm yam kev ua haujlwm kub nyob rau hauv qhov cub hluav taws kub no tuaj yeem pab kom lub alloy kom tau txais kev ua kom zoo thiab microstructure cov khoom.
Txias ua haujlwm: Nws suav nrog cov txheej txheem xws li cov duab txias thiab txias dua, uas tuaj yeem txhim kho txoj kev raug thiab qhov chaw zoo ntawm cov alloy tuav. Nyob rau tib lub sijhawm, nws nce lub zog ntawm cov alloy. Txawm li cas los xij, thaum lub sijhawm ua haujlwm txias, kev saib xyuas yuav tsum tau them los tswj cov nyiaj ua thiab nrawm kom tsis txhob muaj xws li cov kab nrib pleb.
Kev Kho Cua Sov: Feem ntau suav nrog kev kho kom haum thiab kev kho mob laus. Qhov kev daws teeb meem kev kho kub feem ntau nruab nrab ntawm 980-1050 degree, ua raws li los ntawm kev ua kom txias sai kom tau txais ib tug qauv Austenite sai. Kev laus kho qhov kub yog nruab nrab ntawm 700-750 degree, uas tuaj yeem pab kom cov alloy los ua kom zoo dua qub, txhim kho lub zog thiab hardness ntawm alloy.
Daim Ntawv Thov
Roj thiab Roj Teb: Nws yog siv los tsim cov khoom siv roj thiab cov roj ntsha roj drilling, cov khoom siv roj, thiab tuaj yeem tiv thaiv sulfide kev nruam pleb hauv cov roj acidic thiab nkev.
Marine Engineering Teb Teb: Nws yog qhov haum rau cov nkoj fasteners, twj tso kua mis shafts, dej hiav txwv pipelines, thiab tuaj yeem tiv thaiv kev corrosion thiab ntau yam kev yaig hauv cov tub rog marine.
Iberospace Field: Vim tias nws lub zog zoo thiab ruaj khov ntawm qhov kub, nws tuaj yeem siv los tsim cov khoom tseem ceeb, areerospace txheej txheem, thiab lwm yam.
Kev Lag Luam Kev Lag Luam: Nws yog siv los tsim cov khoom siv xws li cov khoom siv hluav taws xob xws li cov khoom siv hluav taws xob, kev hloov pauv cua sov, thiab tuaj yeem tiv thaiv kev yaig ntawm ntau yam tshuaj ntsuab corrosive.
Cov Khoom Siv Polluion Cov Khoom Siv: Piv txwv, nws yog siv los tsim cov roj av uas nkim roj thiab cov khoom ntim dej phwj tuaj, thiab tuaj yeem ua haujlwm nyob rau hauv ib puag ncig nyuaj siab
Cim npe nrov: UN tsis yog N09925 alloy steel bar, Suav teb, manufacturers, chaw muag khoom, Hoobkas
