高荷软莫来石复合砖
H-RUL mullite composite bricks
高荷软莫来石复合砖 是通过提高CaO和耐火材料的反应温度,从而增强了耐火砖抗CaO侵蚀的能力,产品采用双层复合结构,既保证了工作面的优良性能,又降低了耐火砖整体导热系数,产品主要特点:荷重软化温度高、热震稳定性优良、耐压强度高、导热系数低,主要应用于石灰回转窑烧成带和过渡带
H-RUL mullite composite bricks is by improving the reaction temperature of CaO and refractory material so as to enhance the abilitv of refractory brick to resist CaO erosion.The product adopts double layer composite structure,which not only ensures the excellent performance of working surface,but also reduces the overal thermal conductivity of refractory brick.The main features of the product are: High softening temperature under load,excellent thermal shock stability,high compressive strength, low thermal conductivitymainly used in lime rotary kiln firing zone and transition zone.
