Brief introduction Ceramic Fiber, also called aluminum silicate fiber, it is a kind of light weight refractory fiber. It possesses the performances and advantages of high temperature resistance, light, excellent thermal stability, low heat conductivity, small thermal capacitance and mechanical vibration resistance etc. The ceramic fiber needled blanket is the main products of ceramic fiber, it has higher tensile strength and other excellent features. As refractory material, it has found an increasingly wide utilization in the fields of in metallurgy, cement, glass industry, etc. Production process The complete ceramic fiber production line adopts electrical resistance furnace to melt the raw material (such as calcined kaolin clay, alumina, silica, zirconia, etc) into lava. Then the three-roller centrifuge will attenuate the molten fluid into fibers under the centrifugal force of the high speed rotational rollers to the lava. The crude blankets are formed in the collecting chamber and then carried out from the setting chamber. After going through the allocating conveyor, the crude blankets enter into the sintering furnace to be cured. Then the double-layer needling machine will needle the blanket to make the fiber layer tightly interweave with each other. Then after longitudinal and cross cutting, rolling, the crude blankets will become the needled blanket. Equipment Introduction Melting system The electric resistance furnace could use the current generated between the electric resistances to melt the raw materials. Fiber forming system The fiber forming machine is three-roller centrifuge. The high temperature melting fluid will be dispersed and stretched into thin fibers by the centrifugal force of high speed roller. Wool collector The wool collector is used to collect the fibers into crude blanket. The fibers are evenly drawn on the mesh belt under the function of negative pressure air and become crude blanket. Needling machine Needling blanket is developed from the non-woven needling technique. The needle hooks move up and down and draw the fibers to make the fiber layer tightly interweave with each other. This process could improve the tensile strength and the wind erosion resistance performance of the blanket. Sintering furnace It could burn off the lubricant in the blanket and make fiber microcrystalline processing to achieve the heat shaping of the blanket and reach the required thickness and dimension. Cutting and rolling system This system is used to finish the cutting and rolling of the blankets. The blankets will be cut into pieces or strips and rolled into rolls according to the proceeding requirement. PE film, Container
