Zircon product containing special zircon particles

Abstract

The invention relates to a zircon product, in particular to a zircon product containing special zircon particles. The zircon product comprises the following raw materials in percentage by mass: aggregates consisting of 45 to 60 percent of special zircon particles of 0.5 to 5mm and 5 to 15 percent of zircon sand of 0.044 to 0.5mm, matrixes consisting of 25 to 35 percent of zircon powder of less than 44mu m and 2 to 10 percent of zircon micro-powder of less than 5mu m, and 2 to 8 percent of bonding agent. The particles prepared by crushing, acid-washing, drying and screening residual leftovers generated when finished dense zircon brick products are processed are adopted, so that the compact blank stacking principle required by a fireproof material product forming process is met, and the problem that cracks are easy to produce in the process of forming the bricks by only using raw zircon sand and the zircon powder is greatly solved; meanwhile, large products are easy to form during production; and production cost can be saved, the consumption of the raw materials is reduced, and the influence of waste emission on environment is reduced.

Description

technical field [0001] The invention relates to a zircon product, in particular to a zircon product containing special zircon particles, which is suitable for lining bricks of glass or fiberglass furnaces. Background technique [0002] The thermal expansion rate of zircon products is small, and the load softening temperature is relatively high. It can reduce the damage caused by thermal expansion to the furnace body when used in high-temperature kilns; at the same time, because of its good resistance to slag erosion and thermal shock resistance, it can be used as a high-temperature The inner lining of the kiln prolongs the service life of the high temperature kiln. [0003] The raw material of zircon is generally zircon sand, and the particle size of the original sand is generally less than 0.5mm, and most of them are less than 0.2mm. It is easy to crack when producing small-sized products, and it is more difficult to produce products with a size above 300mm, so it is diffic...

Problems solved by technology

[0003] The raw material of zircon is generally zircon sand, and the particle size of the original sand is generally less than 0.5mm, and most of them are less than 0.2mm. It is easy to crack when producing small-sized products, and it is more difficult to produce products with a size above 300mm. It is directly used to produce products; if zircon raw sand and powder are used to briquette and then made into particles, it is difficult to sinter, and the production cost is high
