Basic Refractory Brick

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.

The regular magnesia bricks are made from dense dead burned magnesia that makes the bricks in good refractoriness, corrosion-resistance, and widely used in checker chamber of glass tank, lime kiln, non-ferrous metallurgical furnaces, open heart furnace, iron mixer and EAF of steel-making, and also ferro-alloy furnace, etc.

MgO-C Bricks for steel industry products that have excellent spalling resistance, rust resistance. superior resistance to oxidation.It is used for electric furnace, the second ladle etc and is popular in steel-making industry.

Magnesia Chrome Brick are direct-bonded and made from high grade magnesite clinker and chrome oxide. By high pressure shaping and high temperature firing, its characteristic is the high direct-bonding rate, and big crystallite. It has a good thermal spalling resistance.

The magnesia hercynite brick was prepared with hercynite as raw materials. The application results showed that the kiln coating formed rapidly and stability when using magnesia-hercynite brick. The magnesia-hercynite brick had low thermal conductivity and long service life, and its overall performance was better than magnesia-chrome brick.

Magnesia spinel brick is a kind of basic refractory material which is manufactured by using magnesia and little industrial alumina oxide or bauxiteas raw materials. The thermal shock resistance of magnesia alumina brick is better than that of magnesia bricks, and the refractoriness is above 1580°C, with high corrosion resistance to basic melting slag.
