khoom piav qhia:

Breathable bricks yog peb lub tuam txhab ua cov khoom siv high-tech. Cov khoom siv yog chromium corundum los yog corundum-spinel, thiab cib hom yog ib hom kev taw qhia slit. Tom qab cov khoom tsim, nws yog tsim los ntawm cov cuab yeej siv siab heev xws li kev kho tshwj xeeb thiab kub kub firing. Nws muaj cov yam ntxwv ntawm kev ruaj ntseg siab, siab rov ua dua tus nqi, lub neej ntev, huab cua loj permeability, thiab lwm yam. Nws yog cov qauv zoo tshaj plaws rau hauv qab tshuab argon hauv cov ladle zoo tib yam, LF, LF-VD, VOD, CAS-OB thiab lwm yam khoom siv, thiab yog qhov zoo tagnrho rau kev hloov cov ntshuam. khoom.

Cov khoom muaj cov yam ntxwv ntawm cov qauv ruaj khov, huab cua loj permeability, siab tshuab tus nqi, yaig tsis kam, yaig tsis kam, thiab lub neej ntev. Conducive rau purifying molten steel, uniform muaj pes tsawg leeg thiab kub, haum rau refining furnaces rau kev kho mob mus ntev los yog tshwj xeeb kev kho mob ntawm molten steel.

Cov bricks breathable ua los ntawm peb lub tuam txhab yeej ib txwm muaj kev ruaj khov zoo thiab ua tiav ntau yam. Nws tuaj yeem tsim tau raws li cov neeg siv khoom xav tau, thiab tuaj yeem muab cov khoom sib txuam ntawm cov khoom siv refractory xws li teeb cib, lub rooj cib, thiab cov ntaub ntawv sib koom ua ke. Nyob rau tib lub sijhawm, nws tuaj yeem tsim thiab xaiv cov khoom siv cib ua pa rau cov neeg siv kom ntseeg tau tias kev ua haujlwm zoo ntawm cov txheej txheem argon hauv qab.

Txoj hauv kev puas tsuaj loj ntawm huab cua-permeable cib yog cua sov puas. Nrog kev nce mus tas li ntawm qhov ntsuas kub, muaj qhov sib txawv ntawm qhov kub thiab txias sib txawv ntawm kev ua haujlwm thiab sib quas ntus ntawm qhov chaw ua haujlwm ntawm cov cib ua pa, uas xav tau cov khoom kom muaj cua sov poob siab. Cov theem spinel tau nkag mus rau hauv cov castable, thiab cov cua sov poob siab tsis kam ntawm huab cua-permeable cib yuav zoo dua.

Cov oxide lossis tsis-oxide ntxiv rau hauv cov cib ua pa tsim cov txheej txheem daws teeb meem nrog qhov sib xyaw ua ke ntawm qhov kub thiab txias, ua kom lub zog kub ntawm cov cib ua kom zoo, txhim kho qhov nkag mus ntawm cov cib, thiab tiv thaiv kev yaig ntawm cov cua nkag los ntawm molten slag nyob rau hauv lub ladle. Tom qab kev kho cua sov kub ntawm huab cua-permeable cib, nws qhov kev ua tau zoo dua kom tau raws li nws qhov yuav tsum tau siv.

 

Peb lub tuam txhab tsim thiab tsim impermeable ladle hauv qab argon-blowing slit-type ventilating bricks. Vim tias muaj tsawg dua los yog tsis muaj kev tu thaum siv, kev siv phau ntawv kev cuam tshuam raug txo, uas tuaj yeem txo qhov txawv txav tsis zoo ntawm qhov cua cib los ntawm cov pa oxygen hlawv thiab purging. . Vim nws cov qauv kev tshawb fawb thiab tsim nyog, nws tuaj yeem txo qhov poob ntawm cov pa cib los ntawm thermal stress, mechanical abrasion thiab chemical erosion.
