High-temperature fire clay for coke oven and recycling method of fire clay

Abstract

The invention discloses a high-temperature fire clay for a coke oven and a recycling method of the fire clay. The high-temperature fire clay for the coke oven is composed of clay and fire clay; the recycling method of the high-temperature fire clay for the coke oven comprises the following steps: taking the clay, and removing gravel and stone in the clay; putting the treated clay and used fire clay in a stirring pond, and filling water to the stirring pond; under the room temperature and constant pressure, filling the treated clay and used fire clay in the water in the stirring pond and stir until fully stirring. By adopting the high-temperature fire clay, the usage of the fire clay is effectively reduced, and cost is lowered; the fire clay can reach the sealing effect of the ordinary high-temperature fire clay, and the safety is improved; the recycling method of the high-temperature fire clay for the coke oven can recycle the used fire clay, thus the purchasing amount of the fire clay is greatly reduced and cost is effectively reduced; moreover, the method can reach the sealing effect of the ordinary high-temperature fire clay, and the safety is improved.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to high-temperature refractory mud for coke ovens and a recycling method thereof. Background technique [0002] In the daily production process of the coke oven, it is necessary to use high-temperature refractory mud to seal the coal filling hole cover to prevent the flame and toxic gas from spreading out of the coal filling hole cover after a fire, which will lead to the expansion of the disaster. [0003] However, with the use of high-temperature refractory mud, the sealing effect of the coke oven coal filling hole cover is gradually weakened, so the high-temperature refractory mud needs to be replaced, which increases the cost and requires additional materials for processing, which wastes resources. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a high-temperature refractory mud for coke ovens and a recy...
