Product Description
Magnesium Bricks
Magnesium Bricks is a kind of alkali refractory with over 90% MgO content and adopts the periclase as the main crystal phase with various properties of high refractoriness and good alkali slag erosion resistance, which is mainly used in basic open hearth furnace for steelmaking and hearth and wall of electric stove.
Description for Magnesium Bricks
Magnesium bricks are the main product of alkali refractory and is fired under the high temperature with high refractoriness and resistance to iron oxides and alkali slag and high calcium flux erosion, which is widely used for metallurgical furnaces.
Classification of Magnesium Bricks
Magnesia refractory has MgO as the main component and periclase as the main crystal phase, which is classified into the following types:- Common magnesia brick
- Directly combine magnesia brick
- Magnesia silica brick
- Magnesia chrome brick
- Forsterite brick
- Magnesia alumina brick
- Magnesia-calcium brick
