Abstract

The invention discloses a binder for coke powder molding and an application method thereof which belong to the field of coal. The binder of the invention comprises an A component and a B component, wherein the A component comprises adhesive, adhesion promoter and filling agent; and the B component is surface modifier. The binder of the invention is applicable in the cold bonding forming of coke powder (comprising blue carbon powder, petroleum coke), and finished products can serve as submerged arc furnace raw material, chemical gas raw material, calcium carbide production raw material and thelike, replace some coke and are applied. The application method of the binder of the invention has the advantages of simplicity, no need of raw material for heating and stirring, no need of product carbonization, no pollution in the whole production process, above 95 percent forming rate, more than 3 times of falling from 1m up of wet ball strength, more than 800N/ball finished product strength, 1,000DEG C high temperature resistance, and no dispersion and no powder.

Description

technical field [0001] The invention relates to a binder, in particular to a binder for forming coke powder and an application method thereof, belonging to the field of coal. Background technique [0002] China is a big country of coke production, and its output accounts for more than 60% of the world's total output. It is estimated that the coke output will reach 400 million tons in 2009; in addition, it is estimated that the production scale of semi-coke (also known as semi-coke and coke) in the country will be 45 million tons in 2010. , the total output of petroleum coke is 20 million tons. Coke will produce a certain amount of coke powder during production, crushing, transshipment, loading and unloading, and use. Among them, the amount of coke powder (less than 10mm) in the coking plant of the iron and steel complex is relatively small, generally accounting for 5% of the total coke amount, in order to produce city gas The main coking gas plant has a large amount of coke...
