Cov ntsiab lus tseem ceeb rau kev kho cov ntsia hlau.
1. Ceev faj thaum yaug cov ntsia hlau kom ntseeg tau tias tsis muaj qhov seem seem ntawm cov ntsia hlau tom qab ntxuav nrog silicate tu tus neeg saib xyuas.
2. Cov ntsia hlau yuav tsum tau muab tso rau kom zoo thaum lub sij hawm tempering thiab cua sov kom tsis txhob oxidation me ntsis hauv cov roj quenching.
3. Tej zaum yuav muaj phosphide dawb cov khoom seem nyob rau saum npoo ntawm cov ntsia hlau muaj zog, qhia tias yuav tsum tau ua tib zoo tshuaj xyuas thaum lub sijhawm ua haujlwm.
4. Yog hais tias blackening pom nyob rau saum npoo ntawm ib feem, nws txhais tau hais tias cov txheej txheem kev kho cua sov tsis yog tag nrho thiab cov alkaline residue tsis raug tshem tawm tag nrho.
5. Cov txheej txheem yuav xeb thaum lub sijhawm ntxuav, thiab cov dej yaug yuav tsum tau hloov tsis tu ncua.
6. Yog tias muaj corrosion ntau heev, nws txhais tau hais tias cov roj quenching tau siv ntev dhau lawm thiab cov roj tshiab yuav tsum tau ntxiv lossis hloov.
Peb feem ntau tuaj rau hauv kev sib cuag nrog ntau yam ntsia hlau hauv peb lub neej niaj hnub, los ntawm tsheb kauj vab thiab tsheb mus rau cov khoom siv hluav taws xob xws li khoos phis tawj, xov tooj ntawm tes, MP4s, thiab txawm tias cov iav tsom iav. Screws tau nkag mus rau hauv txhua yam ntawm peb lub neej.
Ntawm lawv, cov ntsia hlau uas tsis yog tus qauv yog hom ntsia hlau dav siv. Cov ntsia hlau tsis yog tus qauv siv ntau yam, xws li stainless hlau daim hlau, engineering installation, hlau hlau daim hlau, galvanized steel daim hlau, thiab lwm yam. Kev sib xyaw ua ke ntawm lub kaum sab xis steel, channel steel, hlau daim hlau thiab lwm yam khoom siv hlau, nrog rau kev sib xyaw ua ke ntawm lub kaum sab xis steel, channel steel, hlau phaj thiab lwm yam khoom siv hlau, thiab lwm yam. Kev sib sau ua ke ntawm cov tsheb hauv tsheb thiab kev lag luam shipbuilding kuj yuav tsum tau cov ntsia hlau tsis zoo.
Vim yog daim ntawv thov dav ntawm cov tsis-tus qauv, koj tuaj yeem xav paub nws cov yam ntxwv. Ua ntej ntawm tag nrho cov, tsis yog-tus qauv screws muaj zog drilling thiab tapping muaj peev xwm thiab tuaj yeem raug xauv hauv ib qho mus. Qhov no ua rau lawv sib raug zoo heev thaum lub sij hawm installation.
