Cr hnov mob nrog cov pa oxygen hauv huab cua, nyob rau hauv tsab xov xwm grate nto tsim ib txheej tuab ntawm oxide zaj duab xis, uas tiv thaiv cov oxidation ntxiv ntawm lub cub tawg grate, tshem tawm cov grate nto qaug zog tawg thiab lub tsheb tawg, tab sis Cr nyob rau hauv ib puag ncig ntawm siab. kub creep, nws yog nyob rau hauv thiaj li yuav txhim kho lub grate ntawm lub zog thiab corrosion kuj, optimized tsim ntawm nws muaj pes tsawg leeg, ntxiv Ni, Mo, V, thiab lwm yam alloying ntsiab, tsim ib tug tshiab hom ntawm tshav kub resistant, siab toughness, siab zog rauv. grate. Piv nrog rau cov khoom siv hluav taws xob kub-resistant hlau, lub neej kev pab cuam ntawm high-chromium alloy tuav yog nce los ntawm 3 zaug, tus nqi raug txo los ntawm ntau tshaj 20 feem pua, thiab tus naj npawb ntawm downtime yog txo, kev siv zog ntawm cov neeg ua haujlwm raug txo, thiab lub neej kev pab cuam ntawm non-high-chromium alloy tuav yog nce los ntawm 90 ~ 180 hnub mus rau ntau tshaj 2 xyoo
Lub grate sawb yog qhov tseem ceeb ntawm lub tshuab sintering, thiab nws txoj haujlwm yog tsim qhov chaw trolley nrog lub laj kab laj kab kom haum thiab nqa cov ntaub ntawv ore. Qhov chaw uas cov grate yog nyob rau hauv kev sib cuag nrog cov khoom siv ore yog qhov saum npoo, thiab ob qhov kawg ntawm lub grate sab saud yog kev ntxhov siab thiab ua lub luag haujlwm txhawb nqa. Hauv qab ntawm lub grate muaj ob lub luag haujlwm, thawj yog lub luag haujlwm ntawm kev kho cov grate thaum tig rov qab unloading, kom nws tsis tuaj yeem poob; Secondly, nws plays lub luag hauj lwm txhawb nyob rau hauv cov ntaub ntawv ntawm lub siab nyob rau sab saum toj ntawm lub grate, uas yuav ua tau zoo tiv thaiv lub grate ntawm dabtsi yog khoov.
Sintering tshuab grate
Cov kev ua haujlwm ntawm lub grate ntawm lub tshuab sintering yog hnyav heev thiab kub hloov pauv tau zoo heev. Qhov kub ntawm cov grate feem ntau yog 800 degree -1000 degree thaum lub sij hawm sintering, tab sis tom qab unloading, qhov txias txias nyob rau hauv cov huab cua sai poob mus rau 100 degree -300 degree . Nws ua haujlwm hauv nruab nrab uas muaj CO, CO2, SO2 thiab dej vapor, thiab raug cuam tshuam thiab kev sib txhuam ntawm sinter hauv kev siv. Lub ntsiab muaj pes tsawg leeg ntawm sintering grate feem ntau yog kub nickel alloy.
Nyob rau hauv tus txheej txheem ntawm sintering system tiam, cov tsis tsim nyog hais soj ntsuam nyob rau hauv lub sintered tiav ore yog siv raws li cov ntaub ntawv hauv paus saum toj no grate bar ntawm sintering tshuab los tiv thaiv ncaj qha kev sib cuag nrog cov sib tov rau daim ntawv cog lus thiab muab tshuaj txhuam, uas ua rau ib tug loj txo nyob rau hauv permeability. ntawm sintering cov ntaub ntawv txheej, uas ncaj qha cuam tshuam rau kev txhim kho ntawm sinter tso zis thiab zoo raws li zoo raws li kev txhim kho ntawm economic thiab technical indicators.
Lub grate sawb yog qhov tseem ceeb ntawm lub tshuab sintering, thiab nws txoj haujlwm yog tsim qhov chaw trolley nrog lub laj kab laj kab kom haum thiab nqa cov ntaub ntawv ore. Qhov chaw uas cov grate yog nyob rau hauv kev sib cuag nrog cov khoom siv ore yog qhov saum npoo, thiab ob qhov kawg ntawm lub grate sab saud yog kev ntxhov siab thiab ua lub luag haujlwm txhawb nqa. Hauv qab ntawm lub grate muaj ob lub luag haujlwm, thawj yog lub luag haujlwm ntawm kev kho cov grate thaum tig rov qab unloading, kom nws tsis tuaj yeem poob; Secondly, nws plays lub luag hauj lwm txhawb nyob rau hauv cov ntaub ntawv ntawm lub siab nyob rau sab saum toj ntawm lub grate, uas yuav ua tau zoo tiv thaiv lub grate ntawm dabtsi yog khoov.
