Dab tsi yog welding slag suav nrog?
Vuam slag inclusions feem ntau muab faib ua ob pawg. Thawj qeb yog hlau slag inclusion, uas yog hais txog cov seem hlau hais xws li tungsten thiab tooj liab nyob rau hauv lub weld, uas yog customarily hu ua tungsten inclusion thiab tooj liab inclusion; qeb thib ob yog non-metallic slag inclusion, uas tshwj xeeb yog hais txog cov hlau seem hauv cov vuam tom qab vuam. Lub slag, nrog rau electrode txheej los yog flux, sulfides, oxides thiab nitrides, thiab lwm yam raws li nws tsim, nws yuav muab faib ua cov ntsiab lus slag inclusions, linear slag inclusions, saw slag inclusions thiab ntom slag inclusions.
Slag suav nrog yuav txo cov plasticity thiab toughness ntawm cov weld, thiab cov slag suav nrog cov ces kaum ntse yuav ua rau muaj kev ntxhov siab nyob rau ntawm lub ntsis, thiab lub taub kuj tseem yuav txhim kho mus rau hauv qhov tawg, tshwj xeeb tshaj yog nyob rau hauv welds nrog siab nyiam cua quenching. Nyob rau hauv qhov kev nyuaj siab ntawm casting, cov kab nrib pleb yuav tshwm sim thawj zaug ntawm cov slag inclusions nyob rau hauv lub weld thiab kis raws, uas ua rau ib tug txo nyob rau hauv lub zog thiab tawg ntawm weld.
Muaj ntau yam tseem ceeb rau kev tsim cov welding slag inclusions. Yog tias muaj ntau qhov sib xyaw ua ke hauv cov khoom siv vuam (xws li cov hlau puag, roj thiab cov khoom siv vuam, thiab lwm yam), nws yuav ua rau muaj kev cuam tshuam hauv cov vuam; Tsis tas li ntawd, cov txheej txheem thev naus laus zis kuj tseem muaj kev cuam tshuam zoo rau kev vuam slag suav nrog.
01.Lub slag nruab nrab ntawm cov npoo ntawm qhov vuam, txheej txheej weld thiab cov hlaws vuam tsis raug ntxuav.
Tshwj xeeb tshaj yog nrog alkaline electrodes, yog tias cov slag tsis raug tshem tawm, nws yog qhov zoo dua los tsim cov slag suav nrog;
02.Vuam tam sim no tsawg dhau
Lub tshav kub tau los ntawm melting cov hlau thiab cov slag tsis txaus, uas txo nws cov fluidity, thiab cov hlau molten solidifies sai, thiab cov slag tsis muaj sij hawm los nto.
03.Tsis tsim nyog tshuaj muaj pes tsawg leeg ntawm lub hauv paus hlau thiab vuam consumables
Piv txwv li, thaum lub pas dej molten muaj ntau cov pa oxygen, nitrogen, sulfur thiab lwm yam khoom, nws cov khoom (oxides, nitrides, sulfides, thiab lwm yam) yuav nyob twj ywm rau hauv lub weld thaum cov hlau molten solidifies sai, thiab yuav nyob twj ywm nyob rau hauv lub weld. . Slag.
Ib qho tseem ceeb ntawm kev tiv thaiv kev koom nrog hauv welds yog qhov kev xaiv ntawm cov khoom siv vuam, zoo deoxidation, desulfurization, thiab lwm yam, ua raws li cov txheej txheem ntsuas.
1. Siv cov khoom siv vuam vuam nrog cov txheej txheem ua tau zoo, thiab txwv tsis pub siv cov khoom siv vuam siv tas sij hawm, tsis zoo thiab tsis zoo;
2. Ua ntej vuam, ntxuav cov xeb, cov roj stains thiab lwm yam tsis zoo hauv qhov chaw vuam. Lub kaum sab xis ntawm qhov zawj yuav tsum tsis txhob me dhau, thiab cov slag hauv qhov zawj thiab ntawm ob sab thiab nruab nrab ntawm txheej yuav tsum tau muab ntxuav.
3. Xaiv cov txheej txheem vuam tsim nyog los ntawm kev ntsuam xyuas cov txheej txheem vuam, thiab xaiv cov kab hluav taws xob tsim nyog raws li lub thickness ntawm lub phaj; Raws li cov kev taw qhia ntawm slag ntws, kho lub kaum sab xis ntawm lub electrode thiab cov txheej txheem ntawm kev thauj mus los txhua lub sij hawm, kom lub slag smoothly ntab mus rau saum npoo ntawm lub pas dej ua ke.
