Zero expansion silica cib

Cov ntaub ntawv refractory siv nyob rau hauv slag kab ntawm lub ladle thaum ntxov tau ncaj qha ua ke nrog magnesia-chrome cib, hluav taws xob melting thiab ces ua ke nrog magnesia-chrome cib thiab lwm yam zoo alkaline cib. Tom qab MgO-C cib tau zoo siv rau ntawm cov hloov pauv, MgO-C cib kuj tau siv rau hauv cov kab slag ntawm lub ladle refining, thiab tau txais txiaj ntsig zoo. kuv lub teb chaws thiab Nyij Pooj feem ntau siv cov khoom sib txuas nrog MgO-C cib nrog cov ntsiab lus carbon ntawm 12% mus rau 20%, thaum Europe feem ntau siv asphalt-bonded MgO-C cib, nrog cov ntsiab lus carbon txog li 10%.

Lub Kokura Steel Works ntawm Sumitomo Hlau Corporation nyob rau hauv Nyiv siv MgO-C cib nrog MgO cov ntsiab lus ntawm 83% thiab C ntsiab lus ntawm 14-17% los hloov ncaj qha bonded magnesia-chrome cib nyob rau hauv VAD slag kab, thiab kev pab cuam lub neej ntawm lub slag. kab tau nce los ntawm 20 npaug rau 30-32 zaug [9]. Lub LF refining ladle ntawm Sendai Steel Plant nyob rau hauv Nyiv siv MgO-C cib los hloov magnesia-chrome cib, thiab cov kev pab cuam lub neej ntawm cov slag kab tau nce los ntawm 20-25 zaug rau 40 zaug, ua tau zoo. Osaka Ceramics Refractory Co., Ltd. tau kawm txog qhov cuam tshuam ntawm cov ntsiab lus carbon thiab cov tshuaj tiv thaiv antioxidant ntawm oxidation tsis kam, slag kuj thiab kub siab flexural zog ntawm MgO-C cib. Txoj kev tshawb no qhia tau hais tias MgO-C cib ua los ntawm kev sib xyaw ntawm fused magnesia thiab sintered magnesia, nrog 15% phosphorus graphite thiab ib qho me me ntawm magnesium-aluminium alloy li antioxidants, muaj kev siv zoo. Thaum siv 100-tuj LF ladle slag kab, qhov kev puas tsuaj yog txo los ntawm 20-30% piv nrog MgO-C cib nrog cov ntsiab lus carbon ntawm 18% thiab tsis muaj tshuaj tua kab mob, thiab qhov nruab nrab yaig yog 1.2-1.3 hli / rauv [1].

Txij li thaum kuv lub teb chaws refined ladle slag kab cib tau txais yuav MgO-C cib es tsis txhob ntawm magnesia-chrome cib, cov kev siv dav tau pom tseeb. Baosteel Group Corporation's 300t ladle slag kab pib siv MT-14A magnesia-carbon cib nyob rau hauv Lub Xya hli ntuj 1989, thiab lub slag kab lub neej tseem nyob saum 100 zaug; 150T hluav taws xob rauv ladle slag kab siv cov pa roj carbon tsawg-magnesia-carbon cib rau smelt qaum hlau, nrog rau qhov kub thiab txias ntawm 1600 ℃ ~ 1670 ℃, uas tau ua tiav cov txiaj ntsig pom tseeb.

Peb lub tuam txhab tshwj xeeb hauv kev tsim cov magnesia carbon cib, aluminium-magnesia carbon cib, tsis yog carbon cib rau refined ladles, aluminium-silicon carbide carbon bricks rau torpedo tso tsheb hlau luam, thiab tshiab carbon-free magnesia cib thiab ntau yam amorphous refractories, xws li kho thiab rab phom cov ntaub ntawv rau converters, hluav taws xob rauv thiab ladles. Peb kuj muab cov khoom tsim kev vibration, xws li ladle air bricks, air-permeable nozzle seat bricks, nozzle seat bricks and prefabricated components. Peb tau tsim los rau hauv ib qho kev lag luam refractory kev koom ua ke ntawm raw cov ntaub ntawv tshawb fawb, sib sib zog nqus ua thiab kev lag luam. Peb lub chaw soj nstuam muaj tag nrho cov khoom siv kuaj thiab tshuaj xyuas. Peb cov cuab yeej tuaj yeem tsim cov khoom siv raw, cov khoom tiav, kuaj thiab tshuaj xyuas, thiab tsim cov khoom tshiab. Peb ntseeg tias kev tshawb fawb thiab thev naus laus zis yog peb cov lus qhia. Yog li ntawd, peb tau txais cov thev naus laus zis hauv tsev thiab txawv teb chaws, txuas ntxiv txhim kho cov khoom zoo, cov ntsiab lus tshawb fawb thiab thev naus laus zis thiab kev ruaj ntseg, yog li txhim kho cov cuab yeej siv thiab niaj hnub hloov kho peb cov khoom siv ntau lawm. Peb muab tag nrho cov kev pab cuam raws li qhov loj thiab kev tsis zoo ntawm converters, hluav taws xob arc rauv thiab ladles raws li tus neeg yuav tsum tau muaj.
