Nrog rau kev txhim kho txuas ntxiv ntawm roj av, tshuaj, tshuaj thiab lwm yam kev lag luam, qhov kev thov rau cov khoom siv tiv thaiv corrosion yog nce. Ntau stainless hlau gratings yog dav siv nyob rau hauv tshuaj lag luam, tshwj xeeb tshaj yog austenitic stainless hlau, uas muaj zoo corrosion kuj thiab thermal stability. Nws muaj kev nce zuj zus hauv cov ntawv thov kev lag luam txhua xyoo. Vim hais tias nws muaj cov nickel siab thiab muaj ib-theem austenite qauv nyob rau hauv chav tsev kub, nws muaj corrosion kuj, siab plasticity thiab toughness nyob rau hauv qis kub, chav tsev kub thiab kub kub, raws li zoo raws li txias txoj kev thiab weldability. 304 stainless hlau yog feem ntau siv hauv steel grating ntau lawm.
Cov yam ntxwv ntawm 304 stainless hlau
Cov khoom ntawm 304 stainless hlau tiaj tus hlau yog cov thermal conductivity tsawg, txog 1/3 ntawm carbon steel, resistivity txog 5 npaug ntawm carbon steel, linear expansion coefficient txog 50% ntau dua carbon steel, thiab ceev ntau dua carbon steel. Stainless hlau vuam pas nrig feem ntau muab faib ua ob pawg: acidic calcium titanium hom thiab alkaline tsawg hydrogen hom. Tsawg hydrogen stainless hlau vuam rods muaj ntau dua thermal tawg tsis kam, tab sis lawv txoj kev tsis zoo li calcium titanium hom vuam pas nrig, thiab lawv cov corrosion kuj tsis zoo. Calcium titanium hom stainless hlau vuam pas nrig muaj cov txheej txheem kev ua tau zoo thiab siv ntau dua hauv kev tsim khoom. Txij li cov hlau tsis muaj steel muaj ntau yam sib txawv ntawm cov hlau, nws cov txheej txheem vuam tshwj xeeb kuj txawv ntawm cov hlau. Stainless hlau gratings muaj ib qho me me ntawm kev txwv, thiab raug rau cov cua sov hauv zos thiab txias thaum lub sij hawm vuam, ua rau cov cua sov tsis sib xws thiab txias, thiab cov vuam yuav ua rau muaj kev ntxhov siab thiab tsis sib xws. Thaum lub longitudinal shortening ntawm lub weld tshaj ib tug tej yam nqi, lub siab ntawm lub ntug ntawm cov hlau grating weldment yuav tsim ntau loj yoj-zoo li deformation, cuam tshuam cov tsos zoo ntawm lub workpiece.
Kev ceev faj rau welding stainless hlau gratings
Lub ntsiab ntsuas los daws qhov overburning, hlawv-los ntawm kev deformation los ntawm stainless hlau grating vuam yog:
nruj me ntsis tswj cov cua kub tawm ntawm lub vuam sib koom ua ke, thiab xaiv qhov tsim nyog vuam txoj kev thiab cov txheej txheem tsis (tsuas yog vuam tam sim no, arc voltage, vuam ceev).
2. Kev sib dhos loj yuav tsum yog qhov tseeb, thiab qhov sib txawv ntawm qhov sib txawv yuav tsum me me li sai tau. Qhov sib txawv me ntsis yog qhov ua rau kub hnyiab los yog tsim teeb meem vuam loj dua.
3. Siv lub hardcover fixture kom ntseeg tau tias sib npaug sib npaug clamping quab yuam. Cov ntsiab lus tseem ceeb uas yuav tsum nco ntsoov thaum vuam stainless hlau gratings: nruj me ntsis tswj lub zog tawm tswv yim ntawm cov vuam sib txuas, thiab siv zog kom txo cov cua sov tawm thaum ua tiav vuam, yog li txo qhov kub ntawm qhov cuam tshuam thiab tsis txhob muaj cov teeb meem saum toj no.
4. Stainless hlau grating welding yog ib qho yooj yim rau siv me me cua sov input thiab me me tam sim no ceev vuam. Lub vuam hlau tsis viav vias rov qab thiab tawm kab rov tav, thiab qhov vuam yuav tsum nqaim dua li qhov dav, nyiam dua tsis pub tshaj 3 npaug ntawm txoj kab uas hla ntawm vuam hlau. Ua li no, lub vuam txias sai sai thiab nyob twj ywm hauv qhov kub thiab txias rau lub sijhawm luv luv, uas muaj txiaj ntsig zoo los tiv thaiv kev cuam tshuam ntawm intergranular. Thaum lub tshav kub input me me, qhov vuam kev nyuaj siab me me, uas yog qhov zoo los tiv thaiv kev ntxhov siab corrosion thiab thermal tawg, thiab vuam deformation.
