Mattone silice-mullite per forni da cemento
Silica-mullite brick is fired bricks composed of mullite (3Al2O3.2SiO2) e carburo di silicio (SiC) come i principali minerali. Its characteristic is that it has the high-temperature resistance of mullite and the wear resistance, resistenza alla corrosione, 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, zona di preriscaldamento, condotto dell'aria terziaria, preriscaldatore a cinque stadi, e scivolo di scarico del forno da calce del forno rotante per cemento.
Comparison between silicon mullite brick and magnesia-alumina spinel
Silicon mullite bricks are suitable for the transition zone of cement kilns as well as mattoni di spinello di magnesia-allumina. Rispetto ai mattoni di spinello di magnesia-allumina, hanno una prestazione di costo più elevata.
Rispetto ai mattoni di spinello di magnesia-allumina, Silica-mullite bricks have the advantages of low thermal conductivity, buona stabilità allo shock termico, 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. Perciò, 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, resistenza alla corrosione, and longer service life than silicon mullite refractory bricks. Used in the transition zone of large cement rotary kilns.
