Preparation method of high-temperature-resistant brick

Abstract

The invention discloses a preparation method of a high-temperature-resistant brick. The preparation method includes the steps that 1, blending is carried out according to the following formula, wherein 89.1-91.2 wt% of Al3O3, 4.1-5.6 wt% of MgO and 4.5-6.8 wt% of CaO are involved in the formula; 2, the ingredients are mixed and ground; 3, water, adhesive and a pore forming agent are added into the ground ingredients for stirring and mixing; 4, slip casting is carried out; 5, the finished product is obtained after drying and sintering. The obtained high-temperature-resistant material is light in weight, high in alkali erosion resistance and low in cost.

Description

technical field [0001] The application belongs to the technical field of materials, and in particular relates to a preparation method of high temperature resistant bricks. Background technique [0002] The use of high temperature resistant materials is one of the important factors for energy saving and consumption reduction of industrial furnaces. The heat storage loss of industrial kiln masonry and the heat loss of the furnace surface generally account for about 24-45% of fuel consumption. [0003] Existing high-temperature-resistant materials generally use mullite and alumina heat-insulating bricks, etc., but such high-temperature-resistant materials usually have technical defects of poor alkali corrosion resistance and high cost. Contents of the invention [0004] The purpose of the present invention is to provide a method for preparing high temperature resistant bricks to overcome the deficiencies in the prior art. [0005] To achieve the above object, the present in...
