Abstract

The invention belongs to the technical field of refractory matters, and particularly relates to a porcelainized aluminum wear-resistant brick and a preparation method thereof, which mainly solve the technical problem that an existing refractory matter is poor in wear-resisting property. The invention has the technical scheme that the porcelainized aluminum wear-resistant brick is prepared from a mixed batch and a binding agent, wherein the mixed batch is prepared from the following raw materials in percentage by weight: 50 to 70 percent of aluminum oxide porcelainized aluminum particle, 10 to20 percent of silicon carbide particle, 10 to 30 percent of bauxite clinker, and 3 to 11 percent of Suzhou clay; the binding agent is a mixture of solid aluminum dihydrogen phosphate and lignosulfite;the additive amount of the binding agent is 3 to 8 percent of the total weight of the mixed batch. The preparation method of the porcelainized aluminum wear-resistant brick comprises the following steps of (1) preparing an aluminum oxide porcelainized aluminum raw material; (2) preparing the binding agent; (3) mixing and milling the raw material; (4) forming to make a blank; (5) drying; (6) firing; (7) cooling to obtain a finished product. The porcelainized aluminum wear-resistant brick provided by the invention has the advantages of high wear resistance, long service life, capability of low-temperature firing, and the like.

Description

technical field [0001] The invention belongs to the technical field of refractory materials, in particular to a vitrified aluminum wear-resistant brick and a preparation method thereof. Background technique [0002] In industrial production, rotary kilns are used in a wide range of fields, such as cement industry, lime calcination, bauxite calcination and other industries. The good wear resistance of the working layer materials in the low temperature area of ​​the rotary kiln head and kiln tail used has always been one of the focuses of relevant scientific and technological workers. [0003] However, the wear resistance of the existing refractory materials is poor. How to apply waste ceramic insulators to refractory materials to improve their wear resistance and prolong their service life is an urgent problem to be solved in industry. Contents of the invention [0004] The purpose of the present invention is to overcome the shortcomings of the prior art, provide a vitrifi...
