1.Dab tsi yog qhov kev hloov kho saum npoo?
Qhov no yog ib qho kev cog lus zoo tshaj plaws tam sim no muaj. Los ntawm kev siv cov dej tshwj xeeb-raws li cov tshuaj passivating los yog hloov kho leveling tov nyob rau hauv cov txheej txheem kawg ntawm txias dov (leveling los yog tiav), ib tug nyias nyias, pob tshab tiv thaiv zaj duab xis yog tsim tom qab kev kho mob.
Cov ntaub ntawv thov tseeb: Lub Yim Hli 2024, Shandong Iron & Steel Rizhao Co., Ltd. tau ua tiav siv Baosteel qhov kev hloov kho tshiab hloov kho tshuab, ua tau ntau tshaj 50 tons ntawm txias-cov khoom dov nrog "degreasing-dawb, siab- huv si." Cov thev naus laus zis no ua tiav xoom nto oiling thaum tswj kev tiv thaiv corrosion zoo heev, sau qhov sib txawv hauv cov roj- pub dawb rau vuam hlau hlau.
2.Dab tsi yog dej- raws li kev kho mob passivation?
Thaum ntxov li xyoo 2015 lub rooj sib tham kev lag luam, cov kws tshaj lij tau thov kom ua tiav cov roj- tiv thaiv xeb dawb los ntawm cov dej saum npoo av- raws li kev kho mob passivation. This method generates a dense passivation film on the steel plate surface to replace rust-preventive oil, which can meet rust prevention needs in short-term or specific environments.
3.Yuav ua li cas hloov txoj kev dov lubrication?
Ib txoj haujlwm tshawb fawb hauv Tebchaws Yelemees tab tom tshawb nrhiav kev siv ncaj qha ntawm "roj-cov roj nplua nyeem dawb" (OFLs) thaum lub sijhawm dov los hloov cov roj ib txwm muaj- dej emulsions. Txoj kev no tshem tawm cov kev taw qhia ntawm cov roj ntawm qhov chaw thiab tuaj yeem txhim kho qhov kev huv huv ntawm cov dov strip.
4.Peb tuaj yeem daws qhov corrosion ntawm nws qhov chaw li cas?
Qhov no yog ib qho kev daws teeb meem ntau dua. Baosteel kuj tau tsim cov thev naus laus zis rau prefabricating corrosion-cov txheej txheem ntawm cov khoom siv raw, tsim cov hlau nplaum los ntawm kev kub thiab txias dov, kom cov khoom kawg nws tus kheej muaj kev tiv thaiv corrosion siab, yog li tshem tawm qhov xav tau ntawm oiling thiab txheej.
5.Dab tsi yog cov ntsiab lus thiab cov lus qhia?
Rau cov neeg siv: Yog tias koj daim ntawv thov xav tau kev huv huv ntawm qhov chaw siab heev (xws li cov vuam hlau, qhov tseeb stamping qhov chaw) thiab koj xav tshem tawm cov txheej txheem degreasing, ces roj -dawb, siab- cov khoom siv huv huv zoo li cov khoom tsim los ntawm Baosteel / Shandong Iron & Steel yog qhov kev xaiv zoo tshaj plaws.
Nws yog ib qho tseem ceeb uas yuav tau xav txog tias cov roj-cov cuab yeej tiv thaiv tsis pub xeb yog feem ntau tsim rau cov khoom tshwj xeeb (xws li steel rau flux-cored vuam hlau) lossis cov kev xav tau tshwj xeeb, thiab lawv lub sijhawm tiv thaiv xeb thiab kev ua tau zoo yuav txawv ntawm cov tsoos xeb- cov roj tiv thaiv. Thaum xaiv ib yam khoom, cov ncauj lus kom ntxaws kev sib tham nrog lub zeb zeb steel yog tsim nyog, coj mus rau hauv tus account koj lub sij hawm cia, ib puag ncig kev thauj mus los, thiab cov txheej txheem tom ntej.
