Abstract

The invention relates to a method for preparing compressive refractory bricks based on natural rocks, and belongs to the field of building materials. According to the method for preparing the refractory bricks provided by the invention, shale, andalusite, dolomite, obsidian, clay, borax are used as raw materials, and the prepared refractory bricks have the advantages of low thermal conductivity. Meanwhile, since the natural rocks are selected as the raw materials, the production cost is saved.

Description

technical field [0001] The invention relates to a preparation method of a compression-resistant refractory brick based on natural rock, belonging to the field of building materials. Background technique [0002] Refractory bricks are an indispensable basic building material for building materials. Including high alumina bricks, magnesia chrome bricks, spinel bricks and other types. However, in view of the shortage of raw material resources and other problems, the cost of raw materials for preparing refractory bricks is getting higher and higher. The strategy of developing green refractory materials is an important development strategy related to the sustainable development of my country's current and future refractory materials industry. Natural rock is a good source of raw materials for refractory bricks due to its large output and low price. Contents of the invention [0003] The purpose of the present invention is to provide a method for preparing a compression-resist...
