Title: Method of removing high magnetic material intermixed into low magnetic material during conveyance and device thereby
Inventor: AOYAMA SHINJI
IPC: B03C1/18
Filed: 1978-01-27
Abstract: PURPOSE: To prevent a conveyor from carrying unnecessary material in such a manner as to detect with a magnet foreign material mixed in a material being conveyed, adsorb the foreign material with an electromagnet installed on a rail above the material being conveyed, release on a movable receiving stand and dump it into a hopper.  
     CONSTITUTION: When loose pieces of steel, etc, mixed in a material 4 being conveyed by a conveyor 1 are detected by a detector 6, an electromagnet 5 is strongly excited by a signal from the detector 6, and therefore, when the foreign material came to the position immediately under the electromagnet, it is adsorbed onto the adsorptive magnetic pole surface. And then, by shifting by means of a driving unit a receiving stand 7 to a position immediately under the electromagnet 5, switch off the excitation of the electromagnet to let the foreign material fall on the receiving stand 7. In this particular case, since magnetic penetrating rate of the foreign material is larger than that of the proper material, the former fall later than the latter and lay on top of the proper material on the receiving stand. In this state, the electromagnet is again excited, that is, weakly excited for adsorbing only the foreign mater ial and strongly excited for picking up the proper material. And the proper material is to be put back on the conveyor by opening a top of a window hole of the receiving stand 7.

Title: Operating method for sintering
Inventor: FUJIMOTO MASAMI
IPC: C22B1/20
Filed: 1985-01-22
Abstract: PURPOSE:To improve the yield of product and productivity in the stage of sintering ore by a downward suction type for forming a sintering layer in such a manner that the binder quantity therein increases from the upper layer toward the lower layer and sintering said layers so that the sinterability of the upper and lower sintering layers is made uniform. CONSTITUTION:The difference in the binder quantity in the above-mentioned sintering layer is formed by, for example, adding an inorg. binder such as CaO, bentonite or quick setting cement component or org. binder only to the raw material to be changed below the intermediate layer of the sintering layer and pelletizing the same. The above-mentioned binder is added in the larger quantity to the raw material to be charged to the layer lower than the raw material to be charged to the upper sintering layer and is pelletized. The raw material added with the binder and pelletized has the higher effect of decreasing the charging density and air permeability in the lower layer. The charging density from the upper layer toward the lower layer increases approximately linearly and the difference in the charging density between the upper layer and the lower layer is large in the case of, for example, the raw material not added with quicklime, as shown in the figure. On the other hand, the charging density of the raw material added with quicklime has the larger charging density from approximately the intermediate point toward the lower layer part as compared to the upper layer. The charging density range of the upper and lower layers is thus reduced and the sinterability of the upper and lower layers is made uniform.
