Pouring glazed tile used for oversized coke oven of specific structure and preparation method thereof

Abstract

The invention discloses a pouring glazed tile used for an oversized coke oven of a specific structure. The pouring glazed tile comprises the following components: secondary alumina, alumina cement, alumina, additives, water, waste quartz glass and waste refractory bricks, wherein the total weight of the waste quartz glass and the waste refractory bricks accounts for not more than 40% of the totalweight of all the components, and the additives comprise spodumene, potassium feldspar, quartz, clay, alumina and water. The invention also discloses a preparation method of the energy-saving and environment-friendly glazed tile. The glazed tile obtained by adopting the preparation method can not produce bubbles, fly glaze or fall off at high temperature of 1300 DEG C, a smooth glaze layer is realized, and expansion coefficient of the glaze layer is close to that of a biscuit firing billet, so that the biscuit firing billet and the glaze layer are basically consistent in thermal expansion andshrinkage, the billet and the glaze layer are free of cracks, thermal expansion coefficient of the overall product is consistent, and thermal expansion problem of the glaze layer and the biscuit firing billet is solved.

Description

technical field [0001] The invention relates to a glazed brick, in particular to a cast glazed brick for coke ovens with a super-large volume and special structure and a preparation method thereof. Background technique [0002] Coke oven door bricks have high technical requirements, not only requiring strong thermal shock stability, penetration resistance, corrosion resistance and carbon deposition resistance, but also meeting energy saving and environmental protection requirements. The manufacturing process of coke oven door bricks meeting the above requirements is complicated and costly, and currently basically depends on foreign imports. Although foreign products have solved the problems of coke cleaning, carbon formation and anti-penetration, they have failed to reduce the surface temperature of the furnace door, the energy-saving effect is not good, and the product price is high. In addition, the size of traditional furnace door bricks is small, not only the masonry pr...

AI Technical Summary

Problems solved by technology

[0005] Purpose of the invention: the purpose of the present invention is to solve the problems of coke cleaning and anti-penetration, but the surface temperature of the furnace door is not reduced, the energy saving effect is not good, and the product price is high. Due to the low degree of environmental protection and the small size of traditional furnace door bricks, the time-consuming and labor-intensive masonry process, comparison documents 1 and 2 did not add waste quartz glass and waste refractory bricks
