Fused quartziferous cast glazed tile for coke oven and preparation method thereof

Abstract

The invention discloses a fused quartziferous cast glazed tile for a coke oven. The glazed tile comprises glazed water and a cast prefabricated member, wherein the glazed water comprises following components in percentage by weight: 30-50% of spodumene with a particle size of 10 to 0 micron, 5-20% of soft clay with the particle size of 10 to 0 micron, 10-20% of potash feldspar with the particle size of 10 to 0 micron, 5-15% of aluminum oxide with the particle size of 5 to 0 micron, 3-15% of quartz with the particle size of 10 to 0 micron, and 0.5-1% of organic plasticizer. The cast prefabricated member includes the following ingredients in percentage by weight: 30-50% of fused quartz, 25-35% of chamotte, 10-15% of alumina clinker, 10-15% of binding agent, 3-6% of silicon micropowder and 3-8% of aluminum oxide micropowder. Meanwhile, the invention further discloses a preparation method of the glazed tile. The glazed tile provided by the invention has excellent thermal shock stability and thermal impact resistance in coke oven production process; the glazed tile has low thermal conductivity and high strength, and can effectively reduce the external temperature of the furnace gate; and the production process does not have pollution.

Description

technical field

[0001] The invention relates to a refractory material, in particular to a fused silica cast glazed brick for coke ovens and a preparation method thereof. Background technique

[0002] Coke oven door lining bricks have been damaged by thermal shock, chemical corrosion and mechanical damage for a long time, and their service life is short. Coke ovens require furnace door lining bricks to have high thermal shock stability and resistance to penetration corrosion and carbon deposition. At present, most of the furnace door lining bricks used in my country are mainly cordierite bricks, pearl bricks, and clay bricks, and the surface is basically not glazed. Among them, cordierite bricks have the longest service life. Cordierite lining bricks have excellent thermal shock stability and meet the thermal shock performance requirements of coke oven doors. However, harmful substances can easily penetrate into the interior of the bricks, reducing the overall physical prop...
