Title: Method for charging raw material for sintering using magnetic force
Inventor: OYAMA NOBUYUKI
IPC: C22B1/20
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To provide a charging method to improve yield by segregating more slid fuel such as cokes in the upper brittle layer of a raw material layer for sintering formed on a pallet of a sintering machine. SOLUTION: A ferromagnetic raw material 1 containing iron and a solid fuel 2 are fed to a preliminary pelletizer 14 to form pseudo particles in advance, and a blended raw material in which the pseudo particle raw material is mixed with other raw materials for sintering is stored in an ore feeding hopper. The blended raw material cut out from the ore feeding hopper is charged onto the pallet through a plate-type sloping chute in which a plurality of permanent magnets are arranged in series along the vertical direction on the rear side. Since a larger amount of raw pseudo particle materials consisting of a raw ferromagnetic material containing iron and a solid fuel are segregated in the upper part of the layer of the raw material for sintering formed on the pallet, the sintering property of the upper layer of the raw material for sintering is improved, and the yield and the cold strength of the sintered ore are improved.

Filed: 1988-06-07
Abstract: PURPOSE:To easily detect abnormity such as layer short-circuit of a high voltage coil by dividing a high output voltage by resistors by means of resistors connected in series at the middle position of the high voltage coil and detecting the voltage directly from a sensing resistor in the series connection resistors. CONSTITUTION:A high output voltage EH of a high voltage output section 4 is divided by resistors 16 connected in series at a tap of the high voltage coil 8 and detected by a sensing resistor 15. Then the detected voltage VD is fed to a comparator circuit 20. The comparator circuit 20 compares a preset value VS with the detected voltage VD and if the detected voltage VD is lower than the set value VS, all abnormal signal is outputted and in other cases, a normal signal is outputted. A latch circuit 21 applies the operating signal to a horizontal oscillation circuit 1 when the abnormal signal is applied from the comparator circuit 20. Thus, the horizontal oscillation circuit 1 stops the horizontal oscillation output or stops the operation of a flyback transformer 4.
