Lolenge ya Matériel Refractaire:
1. Acid refractory material generally refers to refractory material with SiO2 content greater than 93%. Its main feature is that it can resist the erosion of acid slag at high temperature, but it is easy to react with alkaline slag. Silica bricks and clay bricks are commonly used for acid refractories. Silica brick is a siliceous product containing more than 93% of silicon Oxyde. Ba matières premières oyo basalelaka ezali silice, brique ya silicon ya bosoto, etc., oyo ezali na résistance makasi na érosion ya ba scories ya acide, température ya charge ya ko adoucir makasi, rétrécissement te sima ya calcination mbala na mbala, mpe ata expansion ya moke; However, it is easily eroded by alkaline slag and has poor thermal shock resistance. Silica bricks are mainly used in thermal equipment such as coke ovens, glass melting furnaces, and acid steelmaking furnaces. Clay bricks are mainly made of refractory clay and contain 30% to 46% of alumina. They are weakly acidic refractories, have good thermal shock resistance, mpe ezali koboya ba slags ya acide.
2. Basic refractory materials generally refer to refractory materials containing magnesium oxide or magnesium oxide and calcium oxide as main components. These refractories have high refractoriness and are resistant to alkaline slag. For example, magnesia brick, magnesia chrome brick, chrome magnesium brick, magnesium aluminum brick, dolomite brick, forsterite brick, and the Lokola. oyo basalelaka mingi na ba fours ya kosala bibende oyo ezali na alcalin, ba fours oyo ezali konyata bibende oyo ezali na fer te mpe ba fours ya ciment.
3. Aluminosilicate Refractory ezali kolobela matériel réfractoire na SiO2-AL2O3 lokola composante principale. selon contenus na yango ya Al2O3, ekoki kokabolama na semi-silice (al2o{9}}~30%) mpe Clay (al2o{12}}~48)}~48}~48). 48%).
4. Matériel de réfractaire en fondue-casting ezali kolobela produit réfractaire oyo ezali na forme moko boye sima ya ko fondu na température ya likolo na méthode moko boye.
5. Refractaire neutre ezali kolobela biloko ya koboya oyo ezali kosala na pete te na ba slag acide to alcaline na température ya likolo, lokola refractories ya carbone mpe refractories ya chrome. basusu mpe ba attribuer ba réfractories ya alumine ya likolo na catégorie oyo.
6. Matériaux spéciaux réfractaires ezali ba matériaux non métalliques inorganiques ya sika oyo esalemi na ba bases ya ba céramiques traditionnelles mpe ba matériaux réfractaires générales.
7. Matériel réfractaire sans forme ezali mélange ya agrégat réfractaire mpe poudre, liant to admixture supplémentaire. ekoki kosalelama directement to na liquide oyo ebongi. Réfractaire amorphe ezali matériel réfractaire ya sika oyo ezali calciné te mpe ezali na refractoire ya moke te koleka 1580 degrés {{4}
