Hard-facing SAW vuam hlau thiab vuam flux weld fabrication accessories

GEH-507 yog txhais tes electrode nyob rau hauv kab nrog GB / T984 EDCr-A1-15 siv rau li qub thiab lwm yam ntsaws ruaj ruaj. Nws feem ntau ADAPTS rau qhov chaw ua haujlwm kub hauv qab 450 ℃. Nyob rau hauv kev ua lag luam, daim ntawv thov ntawm cov khoom no yog heev dav thiab nrov. Siv tau DC rov qab surfacing siab chromium hlau, surfacing hlau rau 1Cr13, chromium martensitic steel. Raws li peb cov kev tswj hwm nruj ntawm cov khoom zoo thiab cov cuab yeej tsim khoom, kev xa khoom dhau ntawm cov khoom no yog siab heev. Peb tsim 3.2mm, 4.0mm, 5.0mm nyuaj nto hnav-resistant tes electrodes rau cov neeg muas zaub, thiab txhawb cov khoom customization.

Daim ntawv thov & Standard

Cov khoom no feem ntau yog siv rau surfacing li qub thiab lwm yam sealing qhov chaw ntawm high-rise boiler units nyob rau hauv lub hwj chim chaw ua hauj lwm ntawm 570 ℃ los yog hauv qab no. Txais DC rov qab txuas. Cov hlau surfacing yog 1Cr13 semi-ferritic siab chromium hlau. Feem ntau tsis tas yuav tsum tau kho cua sov thaum lub sij hawm vuam, thiab lub hardness yog uniform. Nws tuaj yeem ua rau annealed thiab softened ntawm 750-800 ℃. Thaum rhuab mus rau 900-1000 ℃, nws tuaj yeem rov ua dua los ntawm cua txias lossis roj quenching. Lub tes electrode no kuj siv rau surfacing ntawm ncej thiab valve ntawm carbon steel los yog alloy steel ntawm ua hauj lwm kub hauv qab no 450 ℃. Lub hardness ntawm surfacing txheej yuav tsum tau tswj ntawm li 40.

Nta

GEH-507 yog Tuam Tshoj GB / T984EDCr-A1-15 nyob rau hauv ib tug tsawg sodium hydrogen hom high chromium hlau rau valve surfacing vuam electrode, ua hauj lwm zoo, tsis tshua muaj txaws, yooj yim slag tshem tawm, zoo nkauj zoo nkauj, yuav ua tau yooj yim mechanical processing. Thiab cov txheej saum npoo muaj cov yam ntxwv ntawm huab cua quenching, siab nruab nrab-kub hardness thiab zoo corrosion kuj. Hom ELECTRODE no feem ntau yog siv rau cov hlau hnav thiab ya raws, tsis muaj zog acid thiab lwm yam kev ua ntawm qhov chaw, xws li valve sealing nto, tov khoom slurry, thiab lwm yam. Ua ntej vuam, nws yuav tsum tau qhuav ntawm 300-350 ℃ rau 1 teev. Txhawm rau tshem tawm cov khoom siv hauv paus saum npoo av noo, xeb stains, roj. Thiab peb yuav tsum xyuam xim rau txoj kev ntawm arc thiab arc. Tom qab lub arc yuav arc rov qab hlawv, remelting arc point, thaum lub arc mus sau lub arc qhov.
