Embodiment Construction

[0025] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0026] figure 1 It is a process drawing which shows the manufacturing method of the briquette for steelmaking raw materials which concerns on 1st Embodiment of this invention. In the manufacture of this briquette A, first, the shot blasting waste S generated when ferrous metals are carried out by the shot blasting process is transported by the belt conveyor 1 (refer to figure 1 (a)) while dripping the liquid solidification auxiliary agent D to the shot blasting waste S (refer to figure 1 (b)).

[0027] The above-mentioned shot blasting waste S is a waste slag composed of many used shot beads B and iron metal powder C, etc., which have become smaller than the specified particle size by shot peening, and the aforementioned metal powder contains 60 to 65% by weight. % iron oxide powder. As the aforementioned curing aid D, a 100% solution of sodium silicate wa...

Abstract

PROBLEM TO BE SOLVED: To provide a method for manufacturing briquettes for a raw material for steelmaking in which shot residue can be effectively recycled, and to provide a method for manufacturing the same. SOLUTION: Grinding sludge B which contains grinding-wheel swarf of ferrous metal and grinding fluid containing oil and water is mixed with shot residue S to obtain a flocculent agglomerate M. The flocculent agglomerate M is compacted to prepare a brittle compact C where the grinding-wheel swarf in a fibrous state is roughly sheared and excess water and oil are removed. The brittle compact B is impregnated with an auxiliary agent D for solidification to undergo solidification, followed by drying.

Description

technical field [0001] The present invention relates to a briquette for steelmaking raw materials and a manufacturing method thereof, and particularly relates to a technique for effectively utilizing shot blasting waste generated when ferrous metals are shot blasted. Background technique [0002] The shot blasting waste generated when ferrous metals are shot peened generally contains about 75 to 95% by weight of ferrous metal powders and used shot peening beads (steel balls). Therefore, the aforementioned shot blasting waste can be an effective resource as a raw material for steelmaking. However, this shot blasting waste easily catches fire or splashes. Furthermore, since it contains a large amount of shot beads, it is difficult to cure by compression molding or the like. Therefore, operations such as handling and storage are inconvenient, and it is unfavorable to reuse it both technically and in terms of cost. Therefore, the actual situation is that the shot blasting res...
