Magnesia Dolomite Brick
Magnesia dolomite bricks use high quality bonded dolomite as raw MgO/CaO ratio is adjusted as different need. Fired under high temperature and impregnated by pitch ofin in vacuum. And magnesia dolomite bricks have the advantages of:
1.Good anti-stripping capacity
2.Good thermal shock resistance performance
3.Excellent resistance in slag abrasion
4.Higher temperate resistant with good refractoriness
5.Good cold crush strength
6.High corrosion resistance
7.Low creep and better flaking resistant
8.Less impurities
Magnesia Dolomite Brick Description
Magnesia dolomite bricks are made from qualified magnesite and dolomite as the raw materials that are processed through secondary-burning (calcinations, fine grinding, briquetting, dead burned). The MGO/CaO ratio is taken as the kind of Mag-dolomite brick or unshaped monolithics in accordance with customers requirement. Pitch or paraffin impregnation pressed by vacuum is needed after burned under high temperature. They have the features of high temperature performance and resistance to slag and widely used in the secondary refining vessels as VOD, AOD; Permanent linings or bottom of converter; Ladle and also the cement kiln.
