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.
