Abstract
The utility model relates to a structural integrated composite refractory brick special for a cement kiln, which is characterized in that the refractory brick is formed by high-pressure pressing of a working layer (refractory layer) made of a magnesium oxide material and a non-working layer (heat-insulation layer) made of an aluminum oxide material, wherein the connection surface between the refractory layer and the heat-insulation layer is a plurality of isosceles V-shaped connection surfaces. The structural integrated composite refractory brick has the following advantages that 1, the structural integrated composite refractory brick is fireproof and heat-insulation, and has good energy conservation effect; 2, the integrated structure is reasonable and indestructible; 3, the production cost is lowered; and 4, the product is simple in production, the application method is consistent with that of traditional products, and the product is deeply liked by the majority of users.
Description
Technical field:
The utility model belongs to the refractory brick in the fire resisting material field, says definitely, is to be exclusively used in the structure-integrated composite refractory brick of using in the cement kiln of producing cement.
Background technology:
In the kiln of calcining cement, the refractory brick that uses at present all is the refractory brick of single refractory material compacting.The characteristics of this refractory brick are that fire resistance is good, but heat insulation, heat-insulating property is poor; Its result who causes is that thermal loss is many, and product cost is strengthened.Therefore, people be expected for a long time to solve a kind of can play fire-resistant, can play the composite refractory brick of heat insulation and preservation effect again, and then reach and reduce thermal loss, reduce product cost, improve the purpose of product capacity of competition.The example of this type of composite brick of trial-production was also once arranged in the past, but all failed owing to composite construction is unreasonable.
Summary of the invention:
The purpose of the utility model is to the shortcoming that exists in the problems referred to above, can solve fire-resistant problem for people provide a kind of, can solve structure-integrated composite brick heat insulation, the insulation problem again, and then solves people and thirst for the practical problem that solves for a long time.
The utility model is to be formed by magnesium oxide material working lining (flame retardant coating) that constitutes and inoperative layer (heat insulation, heat-insulation layer) the process high pressure compacting that alumina material constitutes; Joint face between flame retardant coating and heat insulation, the heat-insulation layer is several isosceles V-arrangement joint faces, and the V-arrangement angle is between 20 degree to 160 degree.
Good effect:
After the utility model is realized, can be widely used in the cement kiln, also can be used in other similar pyrolytic semlting stove playing not only fire-resistant, but also heat insulation double action as fire-resistant heat insulating material.Compare with existing refractory brick, the utility model has following advantage: 1, both fire-resistant, heat insulation again, and good energy-conserving effect; 2, after two kinds of raw materials are pressed the interface crimping of V font, structure-integrated reasonable, unbreakable; 3, owing to energy-conservation, and then this product cost is reduced, competitiveness is strengthened; 4, this production is simple and method for using is consistent with old product, is popular in users.
Description of drawings:
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is size, the structural representation of the embodiment of the utility model.
Among the figure, 1-working lining (flame retardant coating); 2-inoperative layer (heat insulation, heat-insulation layer); The positive size of a-refractory brick, height; The positive size of b-refractory brick is long; C-refractory brick lateral dimension, the length of going to the bottom; D-refractory brick lateral dimension, upper base is long; Present position, e-V font interface, height; A-V shape interface two waist angles; F-V shape interface two waist length.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further specified:
Make a wedge shape refractory brick mould by Fig. 1: press following sized: the positive size of a-refractory brick, height is 220 millimeters; The positive size of b-refractory brick, length is 198 millimeters; C-refractory brick lateral dimension, the length of going to the bottom is 64 millimeters; D-refractory brick lateral dimension, upper base length are 59 millimeters.
Other makes the steel plate that a cross section is the isosceles V-arrangement, and long 198 millimeters, wide 62 millimeters, the A angle is 40 degree, and the long f of waist is 15 millimeters.
V-shaped plate is placed mould about 70 millimeters places that go to the bottom; The cavity of going to the bottom is filled alumina raw material (as heat insulation, heat-insulation layer); The upper base cavity is filled raw materials of magnesium oxide (as flame retardant coating); Afterwards, extract v-shaped plate out and be pressed into the adobe of integrative-structure, send into afterwards and be fired into structure-integrated composite fire brick product in the kiln with forcing press.
