Problems solved by technology

[0002] With the technological development of the coking industry, the improvement of process technology and the continuous increase of coking output, correspondingly higher requirements are put forward for refractory materials for coke oven cool coke platform and coke oven roof, but the existing refractory materials have wear resistance. The problems of poor performance and low service life, therefore, need to replace the clinker bricks frequently, which not only affects the normal production of coking coal, but also increases the production cost

Embodiment 1

[0013] Such as figure 1 As shown, the waste ceramics are cleaned and crushed to a particle size of 0.01-5mm, the burnt gems are crushed to a particle size of 0.01-5mm, and the clay and modifier are ground to a particle size of 0.01-0.074mm; after that, 30% of the waste ceramics, 45% of burnt gemstone, 10% of pottery clay and 15% of modifying agent are dry-mixed evenly, and in the modifying agent, the mullite phase is 40%, and the high-silicon vitreous body is 60%. Then add 2% dextrin water mixture of the total weight of the above-mentioned dry materials, the dextrin water concentration is 30%, press molding in a high-tonnage press; then dry in a drying room at 30-60°C for 3 days, and enter the tunnel kiln Fire at a high temperature of 1000-1300°C for 4 hours; leave the kiln to cool and pass the inspection to obtain the finished product.

Embodiment 2

[0015] The waste ceramics are cleaned and crushed to a particle size of 0.01-5mm, the burnt gems are crushed to a particle size of 0.01-5mm, and the clay and modifier are ground to a particle size of 0.01-0.074mm; after that, 55% of the waste ceramics and 20% of the Burnt gemstone, 15% pottery clay and 10% modifier are dry-mixed evenly, and the modifier includes 60% mullite phase and 40% high-silicon glass body. Then add 5% dextrin water mixture of the total weight of the above-mentioned dry materials, the dextrin water concentration is 60%, and press it in a high-tonnage press; then dry it in a drying room at 30-60°C for 5 days, and then enter the tunnel kiln Fire at a high temperature of 1000-1300°C for 8 hours; leave the kiln to cool and pass the inspection to obtain the finished product.

Embodiment 3

[0017] The waste ceramics are cleaned and crushed to a particle size of 0.01-5mm, the burnt gems are crushed to 0.01-5mm, and the clay and modifier are ground to a particle size of 0.01-0.074mm; after that, 45% of the waste ceramics, 35% of the burnt gemstones, and 12 % pottery clay and 8% modifier are dry-mixed evenly, and the modifier contains 50% of mullite phase and 50% of high silica glass body. Then add 4% dextrin water mixture of the total weight of the aforementioned dry material, the dextrin water concentration is 50%, and press it in a high-tonnage press; then dry it in a drying room at 30-60 ° C for 4 days, and then enter the tunnel kiln Fire at a high temperature of 1000-1300°C for 6 hours; leave the kiln to cool and pass the inspection to obtain the finished product.

[0018] In the present invention, waste ceramics (most of which are molded by grouting, glazed on the surface, and have a refractoriness greater than 1500° C.) are used as part of the raw materials. ...

Abstract

The invention discloses a fire, wear and acid resistant clinkery brick which comprises 30 to 55 percent of waste ceramics, 20 to 45 percent of flint clay, 5 to 15 percent of clay, and 5 to 15 percent of modifier. The preparation method comprises the following steps that: the waste ceramics is cleared and crushed into 0.01 to 5mm grain size, the flint clay is crushed into 0.01 to 5mm grain size, and the clay and the modifier are ground into the granularity with 0.01 to 0.074 grain size; and then the dry materials are dry mixed uniformly, dextrin water topping which is 2 to 5 percent of the total weight of the dry materials is added in, pressed, formed, dried and fried for 3 to 8h at the high temperature of 1000 to 1300DEG C; and the materials are drawn and cooled, and a finished product is obtained after the acceptance is past. The invention has the advantages of high pressure resistant strength at normal temperature, smooth product surface, small friction coefficient, low wear rate, good thermal shock resistance, excellent corrosion resistance, low cost and one-step success of coke investment. As estimated, the service life of a coke cooling bench is prolonged by more than 3 times and is expected to be more than 10 years.

Description

technical field [0001] The invention relates to a refractory material, in particular to a refractory, wear-resistant and acid-resistant clinker brick, and simultaneously provides a manufacturing method of the refractory material. Background technique [0002] With the technological development of the coking industry, the improvement of process technology and the continuous increase of coking output, correspondingly higher requirements are put forward for refractory materials for coke oven cool coke platform and coke oven roof, but the existing refractory materials have wear resistance. Therefore, it is necessary to replace the clinker bricks frequently, which not only affects the normal production of coking coal, but also increases the production cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to adapt to the current high requirements for refractory materials used in coke oven cooling platforms and coke oven roofs, an...
