Problems solved by technology

During the coking process, the tar is cooled in the rear half of the furnace door brick and bonded to the brick. Due to the rough surface of the brick, the bond between the tar and the brick is very strong, and it is difficult to remove. Use tools such as tools to remove tar downwards, and at the same time, it is easy to damage the furnace door bricks, shortening the service life of the furnace door bricks

Embodiment Construction

[0019] Referring to Figure 1, Figure 2 and Figure 3, brush or spray ceramic glaze or other glazes on the surface of the furnace door brick or brick 1 with a brush or spray gun, the thickness of the glaze layer 2 is about 0.2-4mm, and enter the kiln after drying Firing in a furnace, the maximum firing temperature is 1250-1400°C, and the temperature is kept for 2-10 hours. The furnace door brick is the finished product after it leaves the kiln. If the glaze layer 2 is less than 0.2 mm, it cannot play the role of the glaze layer; if it is greater than 4 mm, it is unnecessary, and it will also increase the cost and increase the difficulty of manufacture.

Abstract

The invention provides an improved coke-oven door brick and its making method, and its technical project: its characteristic: the surface of the brick has a layer of compact and smooth glaze. It coats and sprays a glaze layer on the surface of the door brick or blank, and burns them together so as to form a compact and smooth glaze layer, thus improving the finish of brick surfaces, preventing and reducing adhesion and conglutination of coke tar, making it easy to eliminate coke tar and simultaneously improving working conditions and labor strength of workers, and also avoiding the damage of the door bricks because of the difficulty in eliminating coke tar.

Description

technical field [0001] The invention relates to a refractory material, in particular to a coke oven door brick and a manufacturing method thereof. Background technique [0002] The existing coke oven door bricks are generally clay or clay-cordierite. Due to the frequent opening and closing of the coke oven door, it is necessary for the furnace door brick to have good thermal shock stability. In order to achieve high thermal shock stability, a larger critical particle size and less fine powder are used; at the same time, the brick It can't be too dense, so the surface of the furnace door brick is rough. During the coking process, the tar is cooled in the rear half of the furnace door brick and bonded to the brick. Due to the rough surface of the brick, the bond between the tar and the brick is very strong, and it is difficult to remove. Use tools such as tools to remove tar downwards, and at the same time, it is easy to damage the furnace door bricks and shorten the service...
