Hnav-resistant surfacing cored hlau flux cored vuam hlau
Flux-cored hlau tseem hu ua hmoov-cored hlau, tubular xaim, nws tuaj yeem muab faib ua ob pawg ntawm kev tiv thaiv roj thiab kev tiv thaiv tsis muaj roj.Qhov saum npoo ntawm flux-cored hlau yog ua los ntawm cov pa roj carbon tsawg lossis cov hlau tsis tshua muaj hlau nrog cov yas zoo.Txoj kev tsim khoom yog tias cov hlua hlau yog dov rau hauv U-shaped seem zoo li, tom qab ntawd cov hmoov vuam tau ntim rau hauv U-shaped steel sawb raws li qhov ntau npaum li cas, thiab cov hlau sawb yog dov nruj los ntawm lub zog zeb, thiab thaum kawg kos. nyob rau hauv txawv specifications ntawm flux-cored hlau.Raws li tag nrho, flux-cored xaim tuaj yeem muab faib ua tus kheej-shielded flux-cored hlau thiab roj shielded flux-cored hlau.Gas shielded flux-cored hlau feem ntau muab faib ua ob lub tshuab slag, uas yog, acidic thiab yooj yim (T 1 thiab T 5).Cov kua qaub slag flux-cored hlau muaj kev ua tau zoo thiab tuaj yeem siv rau hauv txhua txoj haujlwm vuam.Nws yog cov khoom siv dav dav siv cov khoom siv vuam zoo hauv kev lag luam shipbuilding.Lub vuam hlau ntawm cov hlau flux-cored yooj yim muaj cov nyhuv purification zoo, thiab nws tuaj yeem tau txais cov txheej txheem kev ua tau zoo los ntawm kev kho cov qauv tsim nyog, uas yog tsim nyog rau txoj hauj lwm ntawm lub tiaj vuam thiab fillet vuam.
