セメントキルン用シリカムライトれんが

Silica-mullite brick is fired bricks composed of mullite (3Al2O3.2SiO2) および炭化ケイ素 (SiC) 主なミネラルとして. Its characteristic is that it has the high-temperature resistance of mullite and the wear resistance, 耐食性, and good thermal conductivity of silicon carbide.

Silica-mullite brick helps achieve a win-win situation of environmental protection and energy efficiency

In the past few years, environmental protection has become the focus of attention in all walks of life. The application of silica molybdenum bricks lies in their excellent fire resistance, relatively low energy consumption, and environmental friendliness during manufacturing. This advantage makes cement manufacturers prefer silica molybdenum bricks when choosing refractory materials, thus achieving the dual goals of environmental protection and energy efficiency.

Characteristics of silicon mullite brick

Silicon mullite bricks are suitable for the transition zone, 予熱ゾーン, 三次空気ダクト, 5段予熱器, セメントロータリーキルンの石灰キルン排出シュート.

Comparison between silicon mullite brick and magnesia-alumina spinel

Silicon mullite bricks are suitable for the transition zone of cement kilns as well as マグネシア・アルミナスピネルレンガ. マグネシア・アルミナスピネルれんがとの比較, コストパフォーマンスが高いです.
マグネシア・アルミナスピネルれんがとの比較, Silica-mullite bricks have the advantages of low thermal conductivity, 良好な熱衝撃安定性, and high-cost performance; magnesia-alumina spinel bricks have the advantages of stronger corrosion resistance than silico-alumina spinel bricks. The disadvantage of high thermal conductivity is that magnesia-alumina spinel bricks are better resistant to alkali and sulfur erosion in system waste cement rotary kilns. したがって, in large-scale rotary kilns, magnesia-alumina spinel bricks are still mostly used due to safety factors. Carry out masonry.

Comparison of silicon mullite refractory brick and silicon mullite red bricks

Silicon mullite red bricks are denser and have better compressive strength, 耐食性, and longer service life than silicon mullite refractory bricks. Used in the transition zone of large cement rotary kilns.
