Kab lus no yog ua raws li tsab xov xwm kawg hais txog qhov kev xaiv thib ob thiab thib peb ntawm Magnesia carbon cib raw cov ntaub ntawv.
2. Hom magnesium xuab zeb
Muaj peb yam tseem ceeb ntawm magnesium hauv kev tsim khoom: magnesium, sintering magnesium, thiab hluav taws xob melting magnesium.
Hiav txwv Dej Magnesium: Kev tsim cov dej hiav txwv magnesium xuab zeb tau pib xyoo 1855. Qhov zoo ntawm seawater magnesium yog siab purity, MGO cov ntsiab lus siab tshaj 95 feem pua, tshuaj muaj pes tsawg leeg yog yooj yim kho, thiab particle ntim ceev yog siab li 3.30 ~ 3.49g / cm3 ua.
Magnote ntawm sintering magnesium: Advanced sintering magnesium xuab zeb yog cov khoom tsim los ntawm magnesium, dawb huab zeb xuab zeb, chromium hmoov thiab square magnesium pob zeb. Cov yam ntxwv ntawm cov khoom siv siab heev yog: MGO cov ntsiab lus ntawm 96 thiab 99 feem pua thiab cov ntim ntim siab tshaj 3.40g / cm3. Cov magnesium carbon bricks siv nyob rau hauv steel zeb yog tsuas yog siv raws li asphalt los yog resin -binding magnesium carbon bricks rau lub siab noj nyiaj txiag qhov chaw ntawm oxygen -blowing rauv thiab hluav taws xob rauv.
Hluav taws xob magnesium: Qhov thiaj li hu ua hluav taws xob melting yog hais txog lub melting ntawm high-temperature arcs nyob rau hauv lub arc rauv. Nws cov ntaub ntawv raw tuaj yeem yog qib tshwj xeeb ntawm pob zeb diamond magnesium ore lossis high-purity teeb magnesium oxide. Hluav Taws Xob Magles Magnesium xuab zeb muaj qhov kom zoo dua, muaj lub zog loj, muaj lub zog loj, muaj zog tsis kam, hnav tsis kam tiv thaiv , tiv taus slag corrosion. Nws tau dav siv nyob rau hauv high-temperature firing, induction furnaces, arc furnaces, high-temperature yooj yim puas qhov chaw thiab cement rotary kiln hloov bands, furnaces, thiab furnaces ntawm high-temperature tunnel kiln.
Cov qib high-qib hluav taws xob magnesium xuab zeb nplej nplej yog qhov ntau dua 80 μm, thiab cov nplej tau ncaj qha ua ke, yog li muaj ob peb siliconate thiab tsawg lub ntiaj teb siv lead ua; thiab cov nplej ntawm sintering magnesium yog qhov tseem ceeb hauv qab 60 μm - hauv qab cov nplej, thiab cov spar ntawm cov nplej yog ncaj qha ua ke nrog kev sib xyaw ntawm cov nplej. Cov degree tsis zoo, thiab cov nplej tau sau los ntawm qhov qis-melting point silicate, yog li qhov corrosion kuj tsis zoo. Yog li ntawd, feem ntau ntawm cov chaw tsim khoom ntawm magnesium carbon bricks tam sim no siv hluav taws xob magnesium thiab tsis muaj sintering magnesium. Qhov no yog vim li cas.
3. Hom kev khi tus neeg sawv cev
Cov khoom uas tuaj yeem siv los ua ke ntawm magnesium carbon cib yog cov ntsiab lus hauv qab no: thee-based tar, asphalt, thiab roj av asphalt. Cov tsoos asphalt ua ke nrog magnesium carbon bricks yog pheej yig, nrog txhim khu kev qha siv, siab carbon nqi, roj asphalt muaj zog affinity rau magnesium oxide, tab sis vim elasticity ntawm graphite tom qab molding lub cev tsis ntom, thiab tom qab ntawd pib siv cov thermosette phenolic resin. kom tau txais lub cev zoo zog, thiab kev ua haujlwm antioxidant thiab thermal shock kev ua tau zoo dua. Thaum lub sij hawm kho cua sov txheej txheem, phenolic resin thaum kawg tsim ib tug polymer saw iav carbon. Cov khoom-theem carbonization qauv ntawm phenolic resin feem ntau nthuav qhia cov iav-xeev qauv ntawm tib-poj niam txiv neej nyob rau hauv tib poj niam txiv neej. Lub xeev ntws yog inlaid qauv. Cov resin yog solidified ua ntej tsim cov kua-theem txheej ntawm qhov kub thiab txias, tsim oriental carbon, thiab lwm yam directional carbon piv nrog cov heterogeneous carbon, lub qub tau cog lus 90 feem pua, lub tom kawg tau cog lus 5 feem pua, qhov tshwm sim cov ntaub ntawv high-strength ntom. carbon. Thaum tov nrog phenolic resin tov nrog phenolic resin, inlaid qauv yuav tsim nyob rau hauv lub interface ntawm cov ntaub so ntswg carbonized. Qhov kev faib ua feem raug xaiv los nthuav qhia cov qauv ua tiav nrog kev sib xyaw ua ke loj, thaum thermoplastic phenolic resin yuav tsis nce cov pa roj carbon ntau.
