Magnesia Dolomite Brick

Detailed introduction

Magnesia Dolomite Brick

Magnesia Dolomite Brick

Magnesia Dolomite Brick

1. Applications: Mainly used in refining furnace equipment such as AOD, VOD, LF furnace, the cement kilns. The bottom and the permanent laver of steel converters and ladle.

2. Characteristics: The product is made of high quality fused magnesia clinker, two step sintered magnesia dolomite clinker, formed at high pressure, sintered by high temperature, pressed by vacuum and immersion oil or paraffin. Good performance in alkali erosion, volume stability at high temperature, good performance at high temperature strength and good thermal shock resistance.

Advantages of Fused Magnesite Dolomite Brick

Ⅰ、 due to the higher bulk density of Fused Magnesia Dolomite Clinker as raw materials for using, To promote bulk density of Magnesia Dolomite Bricks, and the result is improved washing resistance and erosion resistance.

Ⅱ、 The melting point of materials fused magnesia dolomite clinker is better than the traditional sintered magnesia dolomite clinker, using such raw materials obviously Improve the refractoriness under load of the brick, Improved erosion resistance at high temperature period when decarburizing process.

Ⅲ、 The using of such Fused Magnesia Dolomite Material scan make the CaO content of the brick is relatively lower. Improved the high SiO2 & acid resistance of molten steel water with slag.

Ⅳ、application on the China domestic steel mills, GOR, AOD furnace, use of 20 Fused Magnesia Dolomite Bricks, The effect far better than the ordinary traditional 30 Sintered Magnesia Dolomite Bricks.

1, Weld pool (molten bath) and slag line using 20 fused magnesia dolomite brick at Desheng steel mill 100 tons GOR , furnace life increased about 10 heats compare to the MCa-30 Sintered Magnesia Dolomite Bricks;

2, Tuyere zone and slag line using 20 fused magnesia dolomite brick at Dalian steel mill 50 tons AOD , furnace life increased about 7~11 heats compare to the MCa-30 Sintered Magnesia Dolomite Bricks;
