시멘트 가마용 실리카 멀라이트 벽돌

Silica-mullite brick is fired bricks composed of mullite (3Al2O3.2SiO2) 및 탄화규소 (SiC) 주요 미네랄로. Its characteristic is that it has the high-temperature resistance of mullite and the wear resistance, 내식성, 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, 예열 구역, 3차 공기 덕트, 5단 예열기, 시멘트 회전가마의 석회가마 배출슈트 및.

Comparison between silicon mullite brick and magnesia-alumina spinel

Silicon mullite bricks are suitable for the transition zone of cement kilns as well as 마그네시아 알루미나 스피넬 벽돌. 마그네시아-알루미나 스피넬 벽돌과 비교, 그들은 더 높은 비용 성능을 가지고 있습니다.
마그네시아-알루미나 스피넬 벽돌과 비교, Silica-mullite bricks have the advantages of low thermal conductivity, 좋은 열충격 안정성, 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. 그러므로, 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, 내식성, and longer service life than silicon mullite refractory bricks. Used in the transition zone of large cement rotary kilns.
