Abstract

The invention discloses a method for using coking coal powder as iron making fuel, which relates to a method for producing the coking coal powder into the fuel for iron making. The invention is researched to mainly solve the problem that the present coking coal powder is mostly used for burning bricks or being doped in coal to produce forming coal, and energy sources are fully utilized, to cause very large waste. The coking coal powder is mixed with lime or / and cohesive coal powder through the invention, and mechanical ball making is performed; the weight ratio of the coking coal powder and the lime is 100 : 2 to 6; the weight ratio of the coking coal powder and the cohesive coal powder is 100 : 6 to 9. The invention has the advantages that the coking coal powder is used as the iron making fuel, coking coal is saved, the useful value of the coking coal powder is enhanced to ensure the energy sources to be fully utilized, the waste is avoided, and the production cost of enterprises is also reduced.

Description

[technical field] [0001] The invention relates to an application of coke powder in ironmaking, specifically a method for making coke powder into fuel for ironmaking. [Background technique] [0002] At present, coke powder is mostly used for burning bricks or mixed with coal to make briquettes. The energy is not fully utilized, resulting in a lot of waste. [Content of the invention] [0003] The purpose of the present invention is to provide a method of using coke powder as fuel for ironmaking, so as to make full use of energy, prevent waste and reduce production costs of enterprises. [0004] The object of the present invention is achieved like this: coke powder is mixed with lime or / and cohesive coal powder, and mechanically pelletized; the weight ratio of coke powder and lime is 100: 2-6; The weight ratio of coal powder is 100:6-9. [0005] The invention has the advantages of using coke powder as fuel for ironmaking, saving coke, improving the use value of coke powder,...
