Problems solved by technology

[0007] As a result, the reduced iron powder cannot be smoothly pressed at the center of the roll where the supply of reduced iron powder is small.
Therefore, the reduced iron powder flows downward through the center of the roller in the form of powder, and the briquette cannot be continuously produced, resulting in the problem of excessive loss of the reduced iron powder

Abstract

The present invention provides a briquette manufacturing device to smoothly compact reduced iron powder at the center of a roll. The briquette manufacturing device includes: a feed hopper for supplying reduced bodies containing reduced iron powder; a feed box connected to the lower end of the feed hopper; a pair of rollers combined with the lower end of the feed box, Used to press the reduced body containing reduced iron powder into a briquette; and a pair of cheeks, combined with the feed box, and arranged on both side ends of the roller, wherein the surface of the roller is arranged to form a plurality of There are two cups recessed inward, and the depth of the cup formed at the central portion along the axial direction of the roller is different from the depth of the cup formed at the peripheral portion.

Description

technical field [0001] The present invention relates to a briquette manufacturing device for pressing a reduced body containing reduced iron powder (DRI:directreducediron) into a briquette. More specifically, the present invention relates to a briquette manufacturing apparatus that supplies a reduced body containing fine reduced iron through a plurality of screw feeders. Background technique [0002] Recently, in order to solve the shortcomings of the blast furnace method, iron and steel factories around the world have made great efforts in the development of the smelting reduction ironmaking method. The smelting reduction ironmaking method directly uses ordinary coal as fuel and reducing agent, and directly uses coal as an iron source. More than 80% of the world's ore production is fine ore to make molten iron. [0003] The smelting reduction ironmaking equipment that directly uses fine ore to manufacture molten iron includes a fluidized bed reduction furnace, a briquette ...
