Field of the Invention The present invention relates to a steel slag treatment method, in particular, a steel slag resource treatment method having characteristics of a multi-powder, a high magnetic material, and the like. 5 β 10 15 Ο 20 [Prior Art] Referring to the drawing, the steel slag treatment method i sequentially includes a stacking step 11, a stepping step 12, a magnetic separation step 13, a sorting step 14 and a discharging step 15; wherein the pile material Step u wire pours the 100G~HGGt high temperature liquid steel slag generated during the steel making process onto the ground of the slag yard and sprays water to cool the steel slag 'disintegration and initial stabilization; and then the screening (4) 12 series will The steel in the above (4) is placed in a device having a multi-layer screen size, and a large amount of rinsing and screening is performed by using water, thereby screening different sizes and sizes, that is, re-entering the magnetic separation step 13, by magnetic separation. The machine selects the metal component contained in the steel slag and selects the size of the steel slag according to the size of the steel slag (ie, the step, step 14), and finally selects the applicable particle size and performs subsequent processing and packaging operations according to requirements. (ie, the discharging step 15); further, after the screening of the larger grain acoustic steel, the crushing machine is further processed by a crusher, and then repeated (4), step 12, magnetic separation step. Μ, points, steps 14 steps to ensure that the steel slag is effectively resourced. #惟, steel slag is the waste produced after steel making, but the steel slag can be recycled and resourced with the progress of technology, and it will be produced along with the treatment of steelmaking furnace and different treatment processes. Not 5 steel slag slag, such as slag, desulfurization slag, converter slag, furnace slag 4 200946687 5 ❹ 10 15 Lu 20 and electric furnace oxidation slag also raw materials, relatively, because of the different steel slag containing residual steel, residual Milling the difference between magnetic and sundries and other components, resulting in different subsequent resource treatment, in the case of conventional desulfurization slag, the desulfurization slag is after the blast furnace treatment, the molten iron before the converter must first During the desulfurization operation, during the desulfurization and cooling process, a part of the carbon gas is released and mixed in the desulfurization slag to form a graphite sequin, and the graphite sequin has a light weight characteristic. The desulfurization slag is the same as the following method: 1. In view of the screening step, due to the large amount of washing and screening with water, it is mixed with the desulfurization slag. Bright graphite in sulfur residue The sheet and water penetrate into the multi-layer screen device, and the graphite sequins are followed by water rafting during the rinsing process, which also causes water pollution and graphite sequin contamination problems inside and outside the treatment area, and in addition, an additional area is required. The large site to deal with a large number of sewage problems, and the sediment after sewage treatment needs to be dried, but the impurities contained are too much and difficult to handle, and it is not easy to recycle. 2. In addition, the conventional method is because the screening and sorting steps are performed on a large amount of slag, and in particular, the graphite sequins cannot be removed in the screening step, so that the products of different grades still contain a large amount of graphite sequins after sorting. Mixed, which in turn affects the quality of resource processing. 3. Continue the above-mentioned 'clouds for the products after sorting according to the classification, especially after the fine powder is dried for a period of time, the surface is easy to dry and the graphite flakes of light weight are scattered everywhere in the air, causing air pollution problems. Furthermore, the fine powder of 3 leeches tends to agglomerate, and there is still a problem of graphite sequins after drying, making it more difficult to recycle the product. 5 200946687 [Summary content] Therefore, the object of the present invention is to provide the effects of the magnetic material, the steel material, the treasury #虚#<, the seed 畚 畚 body, and the high steel slag treatment quality.
