Embodiment Construction

[0012] The production process of the above-mentioned example 1 and example 2 is the same, that is: first put the weighed water into the reactor and heat it to 50°C, then mix the weighed sodium humate, cationic starch, and pentonite evenly and then put it into the reactor , stir and heat to 95-100°C, then add weighed sodium silicate and stir, after 50 minutes, add weighed carbon monoxide combustion aid RH series stir and continue heating for 20 minutes, cool down to 70°C, add weighed The ZCM-1 water-soluble flocculant was stirred and continued to heat for 15 minutes, and the coke powder molding adhesive was obtained when the temperature in the reaction kettle dropped below 40°C.

[0013] The method of using the coke powder of the present invention to make molding coke is: mixing the coke powder with a diameter of 0.4-4 mm and moisture ≤ 8% with the product of the present invention having a weight of 15-20% of the coke powder And stir evenly, after being shaped by the mol...

Abstract

The invention, belonging to coal processing technology field, relates to coke powder figuration adhesive, comprising the following steps: adding the water, sodium humate, cationic starch, bentonite, sodium silicate, ZCM-1 water-soluble flocculating agent, carbonic oxide combustion adjuvant into autoclave, stirring, heating, cooling and getting the product. Using the said product, the coke powder can be processed to formed coke. The formed coke possesses the advantages of high fixed carbon, high strength, fire resistant, no explosion, no looseness and no cicatrisation.

Description

technical field [0001] The invention belongs to the technical field of coal processing, and more precisely relates to a coke powder molding adhesive and a production process thereof. Background technique [0002] With the recovery of the global economy and the development of the iron and steel industry, coke is the main fuel for steelmaking, and its consumption is also expanding rapidly. Because coke produces nearly 10% of coke powder in refining and production, and cannot be processed Reasonable use, large storage, dust flying all over the sky, causing great pollution to the surrounding environment, processing at a price nearly 10 times lower than the coke block or being used cheaply, and unable to give full play to the maximum benefit of energy, related companies have spent a lot of manpower Research on physical resources has not achieved obvious results. First, it is difficult to form, and second, its strength is low, which cannot meet the requirements of steelmaking blas...
