Abstract

The present invention discloses a glass melting furnace regenerator top special-use compound spinel zirconium brick comprising 35 to 62 parts of dense corundum, 12 to 18 parts of tabular corundum, 8 to 14 parts of electrically-fused zirconia mullite, 5 to 11 parts of chrome ore, 10 to 13 parts of chrome green, 1 to 4 parts of electrically-fused fused zirconia, 2 to 5 parts of beta-Al2O3 and the proper amount of a binding agent; the above ingredients are put into a powerful sand mixing machine for mixing and ageing mixture for 48h, and then pressed into green bricks on a hydraulic machine, the green bricks are sent into a drying kiln for drying for more than 60 hours, and then fed into a high-temperature tunnel kiln for firing at the temperature of 1600-1650 DEG C to obtain a compound spinel zirconium brick finished product, wherein the cart time is 120 to 150 minutes. The compound spinel zirconium brick finished product can replace other refractory bricks applied to a glass melting furnace regenerator top in the prior art, and greatly improves the life of a glass melting furnace. At the same time a producing method of the compound spinel zirconium brick is simple and has the characteristics of short production cycle and high efficiency.

Description

technical field [0001] The invention relates to a refractory material, in particular to a special composite spinel zirconium brick for the top of a regenerator of a glass melting furnace, and also relates to a manufacturing method of the composite spinel zirconium brick. Background technique [0002] In recent years, my country's glass smelting industry has developed rapidly, and the level of refractory manufacturing and use has been improved, providing a reliable guarantee for the safe operation of glass melting furnaces. So far, the supporting method of using high-grade alkaline refractory materials as refractory materials for glass melting furnace regenerator lattices still occupies a dominant position in my country's glass industry. With the structural adjustment of the glass industry, some kilns with backward technology and high pollution are gradually eliminated and replaced by large environmental protection kilns. However, in order to pursue glass production and impr...
