Abstract

The invention discloses a regenerated brick for a carbon kiln and a preparation method thereof, and relates to the technical field of regenerated bricks and its preparation. The regenerated bricks include raw materials in the following percentages by weight: carbon kiln repair waste bricks 60-80%, high alumina powder 10-20%, pure calcium aluminate cement 4-16%, silicon micropowder 4-5%, three Sodium polyphosphate 0.05-0.15%, sodium hexametaphosphate 0.05-0.15%, explosion-proof fiber 0.05-0.17% and additive 3-4%; the production method is to mix and stir the raw materials into a mixed slurry, cast and mold, demould, Dry it at a constant temperature of 25-35°C. The regenerated bricks of the present invention solve the problems of difficult disposal of carbon kiln waste bricks and high energy consumption and high cost of making regenerated bricks by optimizing raw material preparation and production methods, and realize green recycling of resources and energy saving and environmental protection. In the case of sintering, the refractoriness, compressive strength, high-temperature flexural strength and other properties of the regenerated bricks produced are good, and all meet the use standards.

Description

【Technical field】 [0001] The invention relates to the technical field of regenerated bricks and its preparation, in particular to a regenerated brick for a carbon furnace and a preparation method thereof. 【Background technique】 [0002] At present, many waste materials are produced in the production process of carbon materials in my country. These waste materials are mainly waste bricks produced by carbon kilns. These waste bricks are mainly clay bricks, high alumina bricks and silica bricks. At present, the main treatment method for these waste bricks is burial, which not only takes up a lot of land and damages the environment, but also makes the resources not be used rationally, resulting in waste of resources. Therefore, it is an urgent problem to be solved in the current production of carbon materials to use waste bricks to produce recycled bricks so that they can be reused in production applications and turn waste into treasure. [0003] At present, there are many ways...
