Lub hauv paus ntsiab lus ntawm reverberatory rauv smelting
Nyob rau hauv lub reverberatory rauv smelting txheej txheem, lub ntsiab endothermic cov tshuaj tiv thaiv ntawm cov khoom nqes hav, ua raws li los ntawm exothermic cov tshuaj tiv thaiv uas generates slag. Nyob rau hauv tag nrho cov cua sov tshuav nyiaj li cas ntawm cov txheej txheem smelting, lub tshav kub tso tawm los ntawm generated slag tsis tshaj 6% mus rau 8% ntawm cov cua sov yuav tsum tau rau cov txheej txheem smelting. Yog hais tias lub tshuab cua tsis yog preheated, tag nrho cov cua kub yuav tsum tau rau reverberatory rauv smelting yog 85% mus rau 90% Los ntawm combustion ntawm roj, tsuas yog ib feem me me ntawm tshav kub generated los ntawm roj combustion yog noj nyob rau hauv lub melting ntawm tus nqi, thiab feem ntau. ntawm nws yog muab tshem tawm nrog lub cub tawg roj thiab them nyiaj rau qhov poob. Kev siv roj tiag tiag thaum lub sijhawm smelting yog feem ntau 2 mus rau 3 npaug ntawm qhov kev xav tau.
Graphite Resistance Radiation cua sov rauv kev faib tawm
Raws li txoj kev hloov tshav kub, cov hluav taws xob tiv thaiv tau muab faib ua cov hluav taws xob tiv thaiv hluav taws xob thiab cov hluav taws xob tiv thaiv hluav taws xob. Radiant kuj rauv yog tsuas yog siv rau radiant tshav kub hloov lwm lub tsev, thiab convection tshav kub hloov tsis tau zoo; convection tsis kam rauv yog tsuas yog siv rau convection tshav kub hloov, feem ntau hu ua cua ncig kuj rauv, uas yog rhuab los ntawm cua kub, thiab lub cub tawg kub yog feem ntau qis dua 650 degree.
Lub tshuab hluav taws xob kuj tuaj yeem ua kom sov cov khoom mus rau qhov kub siab heev. Piv txwv li, cov khoom siv hluav taws xob graphitization hluav taws xob tuaj yeem ua kom sov cov khoom rau ntau tshaj 2500 □. Lub qhov hluav taws xob hluav taws xob ncaj qha tuaj yeem ua rau hauv lub tshuab nqus tsev cua sov los yog lub tshuab hluav taws xob tiv thaiv cua sov. Nyob rau hauv hmoov metallurgy, nws yog feem ntau siv rau sintering tungsten, tantalum, niobium thiab lwm yam khoom.
Graphite tiv thaiv hluav taws xob cua sov rauv yog lub qhov cub hluav taws xob uas siv Joule cua sov tsim los ntawm tam sim no dhau los ntawm tus neeg xyuas pib ua qhov cua sov. Lub tshuab hluav taws xob kuj siv hluav taws xob los ua qhov cua sov, thiab hloov hluav taws xob rau hauv hluav taws xob hluav taws xob los ntawm hluav taws xob cua sov cov ntsiab lus, thiab ua kom sov cov hlau hauv qhov cub. Resistance rauv thiab nplaim taws piv, siab thermal efficiency, mus txog rau 50-80?G, yooj yim tswj ntawm thermal system, zoo ua hauj lwm tej yam kev mob, lub neej rauv ntev, haum rau cua sov xav tau workpieces, tab sis siab zog noj.
