Dayang Vuam Khoom Qhuab Qhia Hall|Coj koj nkag siab txog welding cov tsis xws luag-vuam slag
Ua ntej, peb tau kawm qhov kev paub ntawm vuam tsoo thiab porosity. Niaj hnub no, peb coj koj nkag siab txog vuam slag hauv vuam cov vuam tsis xws luag.
Vuam slag yog dab tsi?
Vuam slag raug faib ua ob pawg. Thawj qeb yog hlau slag kev koom tes, tshwj xeeb yog hais txog cov ntawv xov hlau xws li tungsten thiab tooj liab uas tseem tshuav nyob hauv cov hlau txuas, uas yog ib txwm raug xa mus ua tungsten thiab tooj liab suav. Lub pob hluav taws xob hauv lub slag suav nrog txheej electrode lossis flux, sulfide, oxide thiab nitride. Raws li nws tsim, nws muaj peev xwm raug faib ua point slag inclusion, linear slag inclusion, saw slag inclusion thiab tuab slag inclusion.
Slag suav nrog yuav txo qhov plasticity thiab toughness ntawm weld. Slag suav nrog cov ces kaum ntse yuav tsim kev ntxhov siab nyob rau ntawm qhov taub, thiab qhov taub kuj tseem yuav tsim ua lub hauv paus ntawm cov kab nrib pleb, tshwj xeeb tshaj yog nyob rau hauv welds nrog cov nyiam ntau ntawm huab cua quenching. Hauv qab qhov kev ntxhov siab ntawm qhov casting, cov kab nrib pleb yuav tshwm sim thawj zaug ntawm weld slag thiab kis tau raws, uas ua rau txo lub zog thiab tawg ntawm lub weld.
Muaj ntau ntau yam rau kev tsim ntawm vuam slag. Yog tias muaj ntau yam nyob hauv qhov txuas ntawm cov khoom siv vuam (nrog rau lub hauv paus hlau, roj thiab vuam khoom, thiab lwm yam), nws yuav zam dhau kev ua rau cov khoom sib txuas hauv weld; Ntxiv rau, cov txheej txheem txheej txheem tseem muaj qhov cuam tshuam zoo rau vuam slag.
01 .Qhov slag rau ntawm ntug qhov txuas, nruab nrab ntawm vuam txheej thiab weld hlaws tsis tau muab tshem tawm.
Tshwj xeeb tshaj yog nrog cov kua hluav taws xob alkaline, yog tias lub slag tsis raug tshem tawm, nws yog tus tsim ntau hauv slag sib ntxiv;
02 .vim tam sim no me dhau
Cov tshav kub tsis txaus yog tau txais los ntawm molten hlau thiab slag, uas txo nws cov fluidity, thiab molten hlau solidifies sai sai, thiab slag tsis muaj sijhawm los ntab tawm.
03 .Txoj tsis huv hauv tshuaj lom neeg cov hauv paus hlau thiab vuam khoom
Piv txwv li, thaum muaj ntau yam sib xyaw ua ke xws li oxygen, nitrogen, thiab cov leej faj nyob rau hauv pas dej molten, nws cov khoom (oxides, nitrides, sulfides, thiab lwm yam) yuav nyob hauv cov hlau txuas yog tias tus hlau molten solidifies sai thiab tsis muaj sijhawm ua kom ntab tawm Slag.
Ib qho tseem ceeb ntawm kev tiv thaiv kev koom tes hauv qhov txuas yog qhov xaiv qhov tseeb ntawm vuam consumables kom zoo dua deoxidize thiab desulfurize, tom qab ntawd saib xyuas cov txheej txheem ntsuas.
01. Vuam siv nrog cov txheej txheem kev ua tau zoo siv, thiab nws yog txwv tsis pub siv cov khoom siv uas tau tas sij hawm, ploj thiab muaj qhov tshwm sim zoo;
02 .Ua ntej ua vuam, ntxuav xeb, roj thiab lwm yam cuam tshuam tsis zoo nyob rau hauv chaw vuam. Lub kaum sab xis ntawm lub zawj yuav tsum tsis txhob loj dhau. Lub pob slag hauv qhov zawj thiab ntawm ob sab thiab nruab nrab ntawm txheej yuav tsum tau muab ntxuav.
03 .Txoj xaiv vuam cov txheej txheem tsim nyog los ntawm kev soj ntsuam cov txheej txheem vuam, thiab xaiv cov xaim hluav taws xob ntawm lub cheeb tsim nyog raws li cov tuab ntawm phaj; raws li cov kev taw qhia ntawm cov dej slag, kho lub kaum sab electrode thiab cov qauv ntawm kev thauj mus los txhua lub sijhawm, kom lub slag tuaj yeem ntab ntab rau saum npoo pas dej.
Ua li,
Qhov ntawd' s txhua yam rau hnub no' s lus qhuab qhia.
