Abstract
The utility model relates to a refractory brick provided with a toothed high temperature resistant layer on the surface and arranged at the high temperature part of a liner of a rotary kiln. The refractory brick is formed by a refractory layer and an insulating layer and is provided with a metal anchoring element; a toothed alumina ceramic hollow sphere layer is arranged on the outer surface of the refractory layer of the refractory brick; the metal anchoring element is an M-shaped metal anchoring element, and penetrates the refractory layer and the insulating layer. According to the novel refractory material for building a rotary kiln, provided by the utility model, the toothed alumina ceramic hollow sphere layer is arranged on the surface layer of the refractory brick, and the ceramic hollow sphere for delivery is high in intensity and strong in wear resistance as well as excellent in mechanical strength and higher in use temperature after firing. Therefore, the refractory brick has the advantages of light weight, high temperature resistance, excellent thermal shock resistance and long service life.
Description
Technical field
The surface that the utility model relates to a kind of high temperature position setting at inner liner of rotary kiln is the refractory brick of dentation high-temperature-resistant layer.
Background technology
In existing inner liner of rotary kiln, the refractory material laying brick entirety resistance to elevated temperatures of employing is poor, and especially in use its resistance to elevated temperatures is poor, directly causes the service life of brick short.Day by day exhausted at traditional energy, and today of new forms of energy slower development, the most urgent current task is that exploitation lightweight, high temperature, good thermal shock stability, serviceability temperature high energy meet the required inner lining material of light structures high temperature furnace, change 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, saving the energy, is human kind sustainable development service.Especially how adopting better exotic material in the high temperature section of rotary kiln 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 aluminium oxide ceramics hollow ball that raw material produces by waste old ceramics as the surface of high temperature resistance superficial layer as the refractory brick of dentation high-temperature-resistant layer.
The purpose of this utility model is achieved in that a kind of refractory brick of dentation high-temperature-resistant layer, comprise the refractory brick with metal anchorage being formed by flame retardant coating and heat-insulation layer, it is characterized in that: the aluminium oxide ceramics hollow ball layer that is provided with dentation on the flame retardant coating outer surface of refractory brick.
Described metal anchorage is M shape metal anchorage, is applied in flame retardant coating and heat-insulation layer.
According to above technical scheme, the rotary kiln refractory material of building by laying bricks or stones of the present utility model, due to the aluminium oxide ceramics hollow ball layer of the outermost use dentation at refractory brick, and ceramic material hollow ball while dispatching from the factory through firing, intensity is high, wearability is strong, has the serviceability temperature of good mechanical strength and Geng Gao, therefore the utlity model has the advantage of lightweight, high temperature resistant, good thermal shock stability, long service life.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model.
The specific embodiment
Embodiment 1: as shown in Figure 1, a kind of refractory brick of dentation high-temperature-resistant layer, comprise the refractory brick with metal anchorage 3 being formed by flame retardant coating 1 and heat-insulation layer 2, it is characterized in that: the aluminium oxide ceramics hollow ball layer 4 that is provided with dentation on the flame retardant coating outer surface of refractory brick.Described metal anchorage 3 is M shape metal anchorage, is applied in flame retardant coating 1 and heat-insulation layer 2.
Ceramic material hollow ball layer is take waste old ceramics as primary raw material, and the aluminium oxide of introducing adjusting viscosity is additive, and melting in three-phase alternating current or DC electric arc ore-smelting furnace jets to manufacture ceramic material hollow ball with air.
Claims (2)
1. the refractory brick that surface is dentation high-temperature-resistant layer, comprise the refractory brick with metal anchorage (3) being formed by flame retardant coating (1) and heat-insulation layer (2), it is characterized in that: the aluminium oxide ceramics hollow ball layer (4) that is provided with dentation on the flame retardant coating outer surface of refractory brick.
2. surface according to claim 1 is the refractory brick of dentation high-temperature-resistant layer, it is characterized in that: described metal anchorage (3) is M shape metal anchorage, is applied in flame retardant coating (1) and heat-insulation layer (2).
