Description
Technical Field
The utility model belongs to the field of composite high-temperature heat-insulating refractory materials, and particularly relates to a refractory composite heat-insulating module structure.
Background
Under the condition that the content of sulfur, alkali metal and chloride ions in the cement raw materials is high, the refractory material of the cement sintering system can be adhered to the surface of the refractory material to form a non-falling crust layer, so that the smooth production of the cement kiln is affected. The usual solution is to use a layer of microcrystalline silicon carbide ceramic plate of 25-50 mm on the hot face of the refractory material and then to fix it to the cold face steel shell by means of metal tie rods, between which casting and insulating plates are applied. However, when the casting material and the heat insulation plate are constructed on site, the heat insulation plate is difficult to be completely placed in the cold surface part because dense metal pull-fixing and anchoring parts are distributed behind the microcrystalline ceramic plate; meanwhile, because the metal is pulled and fixed and the anchoring piece are manually welded in narrow airtight equipment on site, the welding strength is high for a long time, and the welding quality is difficult to ensure; and finally, when the construction castable is poured between the microcrystalline ceramic plate and the heat insulation plate, the construction labor intensity is high, the construction time is long, and the preset furnace opening time is often influenced due to overlong construction time.
CN215337719U discloses a composite structure of refractory lining, the problem of this patent is that the small i-shaped ceramic fastener clamped in the dovetail groove breaks at the interface of the casting material and the ceramic plate, that is to say the strength of the small i-shaped ceramic fastener is insufficient, due to the high-temperature expansion force of the casting material in use.
CN216080986U discloses a special-shaped ceramic plate and a composite structure for refractory lining, the special-shaped ceramic plate comprises a plate body, a boss is integrally manufactured on one surface of the plate body, the boss is vertical to the plate body, and a perforation is formed on the boss. The boss can be made to be wide and thick, and the strength is enough to resist the expansion force of the castable at high temperature, so that the whole structure of the special-shaped ceramic plate is kept from being broken, and the expected service life is achieved.
However, CN216080986U requires passing heat resistant steel on site, installing and welding U-shaped heat resistant steel fasteners, and the construction speed is so slow that users abandon the use of such a structure due to insufficient downtime.
