Problems solved by technology

[0003] However, the coal mills in the coal workshops of many iron and steel enterprises were put into operation earlier. Later, with the commissioning of multiple blast furnaces and the pursuit of a large coal ratio to reduce consumption of blast furnaces, the output of coal mills was insufficient to meet the injection volume of blast furnaces.
[0004] In the existing technology, the coal mills put into production by many iron and steel enterprises do not have the safety of grinding bituminous coal, the price of using pure anthracite is high, and the cost per ton of iron remains high

Embodiment Construction

[0027] The specific implementation of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.

[0028] Such as figure 1 , figure 2 The expressed structure of the present invention is a blast furnace bituminous coal long-distance transportation and distribution system. It is a method that does not have a mill for direct production of bituminous coal powder and is equipped with bituminous coal injection.

[0029] In order to solve the problems existing in the prior art and overcome its defects, and realize the invention purpose of reducing the production cost of the blast furnace, the technical scheme adopted by the present invention is:

[0030] Such as figure 1 and figure 2 As shown, the blast furnace bituminous coal lo...

Abstract

The invention discloses a remote blast furnace bituminous coal conveying and allocating system which comprises a bituminous coal unloading and loading device, a bituminous coal receiving and allocating device, and a tank truck (3), wherein the distance between the bituminous coal unloading and loading device and the bituminous coal receiving and allocating device is not greater than 200km. Due to adoption of the technical scheme, the problems of addition and blowing of the bituminous coal in a mill which cannot directly produce bituminous coal powder are solved, so that the blank that bituminous coal powder is produced by using a blast furnace is made up, the bituminous coal ratio of the blast furnace is increased, and the fuel consumption is reduced; long-distance transportation of bituminous coal powder is achieved, the problem that the capacity of a powder production workshop of a steel company is not sufficient is thoroughly solved, the working time of workshop personnel is shortened and the working burden of the workshop personnel is alleviated, the coal to coke replacement ratio in steel production is increased, and the cost of every ton of steel is remarkably lowered.

Description

technical field [0001] The invention belongs to the technical field of fuel production in the metallurgical industry, and relates to a technical solution for transportation and distribution of fuel. More specifically, the invention relates to a system for long-distance transportation and distribution of blast furnace bituminous coal. Background technique [0002] Most of the pulverized coal used for injection in existing medium and large blast furnaces comes from coal mill grinding and is directly injected into the blast furnace. [0003] However, the coal mills in the coal workshops of many iron and steel enterprises were put into operation earlier. Later, with the commissioning of multiple blast furnaces and the pursuit of a large coal ratio to reduce consumption, the output of the coal mills was insufficient to meet the injection volume of the blast furnace. [0004] In the existing technology, the coal mills put into production by many iron and steel enterprises do not h...
