JUCOS Refractories > Shaped Refractories > Magnesia Dolomite Brick
Product Details

Magnesia Dolomite brick 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.

Features Of Magnesia Dolomite Brick

  • Good thermal shock resistance performance
