Galvanized round steel kav muaj qhov zoo ntawm cov txheej txheej, muaj zog adhesion, kev pab lub neej ntev thiab lwm yam. Tus nqi zinc plating yog tsawg, thiab qhov saum npoo tsis du heev.

Cov yam ntxwv ntawm galvanized steel vuam
Galvanized steel yog feem ntau qis carbon steel plated nrog zinc, zinc txheej yog feem ntau 20um tuab. Nyob rau ntawm 419 ° C, lub boiling point ntawm txog 908 ° C melting point ntawm zinc. Nyob rau hauv vuam, lub melted kua zinc da dej ntab rau saum npoo los yog nyob rau hauv lub hauv paus ntawm qhov chaw weld. Zinc muaj ntau dua solubility nyob rau hauv hlau, zinc etching kua yuav nkag mus rau hauv cov hlau weld raws li ib thaj tsam ntawm grain, tsawg-melting zinc los ua ib tug "kua hlau embrittlement." Lub caij no, zinc thiab hlau brittle intermetallic tebchaw tuaj yeem tsim tau, cov txheej txheem nkig no kom cov vuam hlau yas qis dua hauv tensile kev nyuaj siab thiab tawg. Yog hais tias lub fillet weld, tshwj xeeb tshaj yog cov fillet weld T-joints feem ntau nws nkag mus rau cov kab nrib pleb. Thaum vuam galvanized steel, zinc txheej thiab qhov chaw ntawm qhov zawj ntawm ntug ntawm arc nyob rau hauv qhov kev txiav txim ntawm tshav kub, oxidation, melting, evaporation thiab volatile dawb pa luam yeeb thiab chav, tuaj yeem yooj yim ua rau weld porosity. ZnO vim oxidation thiab tsim ntawm nws qhov siab melting point ntawm txog 1800 degree C los yog ntau tshaj, yog hais tias me me parameter nyob rau hauv lub vuam txheej txheem, yuav ua rau ZnO slag, tib lub sij hawm. Txij li Zn ua deoxidizer. Ua FeO-MnO lossis FeO-MnO-SiO2 qis melting point oxide slag. Thib ob, vim yog cov evaporation ntawm zinc, volatile ntau ntawm cov pa luam yeeb dawb, los txhawb tib neeg lub cev, muaj kev phom sij, yog li ntawd, yuav tsum tau welded zinc txheej ntawm polished.
