PLC and DCS controlling system.
Electric resistance furnace production technics.
1260,1360 and 1430 grade ceramic fiber blanket.
Density 80-160kg/m3 ceramic fiber blanket.
Thickness 10mm to 50mm ceramic fiber blanket.
The flint clay is to be crushed to the required size for making standard ceramic fiber. Industrial alumina powder, industrial silica powder and zirconium power with different percentage are properly mixed for making four different types of products. Such as standard ceramic fiber, high alumina ceramic fiber, high purity ceramic fiber and zirconium-containing ceramic fiber.
When making different products, the above specific raw materials are prepared, delivered and evenly distributed in an electric resistance furnace after fixing through feeding set and mixer. The electric resistance furnace uses the molybdenum electrode as power source. The ion produced by melted raw material is conductive. The resistance of melted raw material works as heating element and melts the raw material continuously and uniformly. The electric resistance furnace is water-cooled. The molten stream discharged through a single molybdenum outlet port, which is protected with nitrogen. A spinning machine with three high velocity spinning discs transforms melted material into fiber through centrifugal force; Intenerating reagent is used during fiberization. Fibers are flown away from the spinner and evenly distributed on the collecting belt through the action of negative voltage. Then through photoelectricity (weighing up system) control of the collection system and PLC system, conveying speed will change according to the required specific weight and thickness. The fiber enters the stitching machine through conveying strap, the stitching machine transforms the fiber into blanket in requirement.
The blanket goes through a heat treatment furnace to burn out Intenerating reagent, fix the shape of blanket, microcrystalline the fibers and improve its operating temperature. Through longitudinal and cross cutting, rolling up, quality control and packing, the finished products are sent to the warehouse for dispatching.
The technology function of the equipment is the same with "ALT-TSB-DZL-SS-2000", the power use the 1350KVA magnetism booster, the flowing mouth by the 100KVA magnetism booster. Because the big power, the capacity of fibers is increased, comparatively, the cost of production will low, and increase the profit of clients.
