Boric sludge fire resistant ceramsites

Abstract

The invention provides boric sludge fire resistant ceramsites, relates to a fire resistant ceramsite aggregate formed by taking boric sludge as a main raw material. The boric sludge fire resistant ceramsites are invented mainly to solve the problem that at present, the boric sludge occupies a vast area and causes environmental pollution, the problem that the conventional boric sludge ceramsites is poor in high temperature resistance and the like. The boric sludge fire resistant ceramsites are prepared form the following raw materials in percentage by volume: 60 to 75 percent of boric sludge, 20 to 30 percent of magnesium slag, and 5 to 10 percent of bonding agent. The production method comprises the following steps of: grinding all raw materials, mixing the ground raw materials and addingwater; granulating the mixture by a granulator; and baking the granules in a rotary kiln to obtain the boric sludge fire resistant ceramsites. The boric sludge fire resistant ceramsites have the advantages of replacing clay ceramsite and high-aluminum ceramsite, prolonging the service life of a hearth when used for building the hearth and reducing the building cost of the hearth and producing various fire resistant concrete, fire resistant building blocks, fire resistant filling materials and the like; and the boric sludge fire resistant ceramsites also solve the problems that the boric sludge occupies a vast area as well as causes environmental pollution and also have quite obvious social benefits.

Description

Technical field: [0001] The invention relates to an aggregate made of boron mud as a main raw material - refractory ceramsite. It is mainly used for boiler masonry, heat preservation treatment of thermal equipment or as refractory filler, refractory blocks, etc. Background technique: [0002] Borax mud is the waste residue discharged from the production of borax. A large amount of boron mud discharged from the annual production of borax in my country, especially in Liaoning Province, not only occupies a large amount of land but also pollutes the environment; Clay ceramsite has poor high temperature resistance and can only withstand a temperature of about 900°C, which often cannot meet the needs of production. Invention content: [0003] The technical problem to be solved by the present invention is to provide a kind of boron mud refractory ceramsite produced with boron mud as the main raw material and has good high temperature resistance. [0004] The object of the presen...
