Abstract
The utility model relates to a high temperature resisting, scouring resisting and wear resisting chute used as a refractory material in the chute of a rotary kiln system. The high temperature resisting, scouring resisting and wear resisting chute comprises a refractory layer and a thermal insulation layer positioned below the refractory layer, wherein the refractory layer and the thermal insulation layer positioned below the refractory layer form a groove-shaped structure, a steel plate is arranged on the refractory layer on the two side surfaces of the chute, a fireproof fiber layer is arranged on a bottom surface between the two side surfaces of the chute, and the steel plate and the fireproof fiber layer are covered with a layer of aluminium oxide ceramic hollow ball layer. According to the utility model, the aluminium oxide ceramic hollow ball layer is used as the surface of the chute, and through burning to aluminium oxide ceramic hollow balls when delivery, the strength is high, the wearing resistance is strong, and better mechanical strength and higher using temperature can be achieved. Therefore, the high temperature resisting, scouring resisting and wear resisting chute provided by the utility model has the advantages of high temperature resistance, scouring resistance, light weight, good thermal shock resistance and long service life.
Description
Technical field
The utility model relates to a kind of high temperature resistance antiscour wear-resistant chute using as refractory material in rotary system chute.
Background technology
In existing rotary kiln chute, the refractory material laying chute of employing, chute entirety resistance to elevated temperatures is poor, can directly cause chute to damage, and shortens the service life of whole chute.Day by day exhausted at traditional energy, and today of new forms of energy slower development, the most urgent current task is the chute inner lining material of exploitation lightweight, high temperature, good thermal shock stability, change chute in traditional superhigh temperature kiln because the thermal capacity that adopts heavy structure to exist is large, heating rate is low, energy consumption is large, service life is short, maintenance capacity in the mid-term shortcoming such as large, save the energy, especially how adopting better resistance to erosion exotic material in the high temperature section of rotary kiln chute is a problem.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of to do the aluminium oxide ceramics hollow ball of raw material production by waste old ceramics as the high temperature resistance antiscour wear-resistant chute of high temperature resistance antiscour superficial layer.
The purpose of this utility model is achieved in that a kind of high temperature resistance antiscour wear-resistant chute, comprise flame retardant coating, be positioned at the heat-insulation layer below flame retardant coating, it is characterized in that: flame retardant coating and the heat-insulation layer being positioned at below flame retardant coating form groove shape structure, on this groove two sides flame retardant coating, be provided with steel plate, on the bottom surface between these groove two sides, be provided with fire proofing firbre layer, on steel plate and fire proofing firbre layer, be coated with one deck aluminium oxide ceramics hollow ball layer.
The surface of the utility model using aluminium oxide ceramics hollow ball layer as chute, when aluminium oxide ceramics hollow ball dispatches from the factory, process is fired, intensity is high, wearability is strong, there is the serviceability temperature of good mechanical strength and Geng Gao, therefore the utlity model has the advantage of high temperature resistance, antiscour, lightweight, good thermal shock stability, long service life.
