Abstract
The invention discloses zirconium mullite and a process thereof and relates to zirconium mullite used as a refractory material and a process thereof. The zirconium mullite comprises the following components in percentage by weight: 29-61 percent of gamma-Al2O3 and 40-70 percent of zircon sand. Furthermore, the zircon sand comprises the following two components in percentage by weight: larger than 65 percent of zirconium dioxide and larger than 33 percent of silicon dioxide. The zirconium mullite is obtained by adding zircon sand according to the proportion and producing according to the process, and the produced zirconium mullite has the performances of higher abrasive resistance, thermal vibration resistance, chemical erosion resistance, and the like compared with the traditional mullite.
Description
Technical field
The present invention relates to a kind of zirconium mullite and complete processing thereof as used for refractory material, this zirconium mullite is widely used in the refractory materials on the various Thermal Equipments in the industries such as iron and steel, glass, pottery, petrochemical complex.
Background technology
As refractory materials commonly used, the application of mullite is very extensive, but along with developing rapidly of iron and steel, Glass lamp industry, demands for higher performance to refractory materials, particularly require to have heat-shock resistance preferably, in glass industry, then need antistripping erosion performance preferably, but present mullite does not generally satisfy this demand; So added the material of zr element in the present mullite, to improve performances such as its heat-shock resistance, chemical corrosion, obtained the comparatively refractory materials of ideal performance, but adding zr element and other component ratio differ in each production firm, quality is uneven, and the zirconium mullite quality that a lot of production firms produce can not get guaranteeing.
Summary of the invention
The present invention is directed to above-mentioned defective, purpose is to provide a kind of to be had good thermal shock resistance performance and has the zirconium mullite and the complete processing thereof of good chemerosiveness resistent.
