Title: Treatment of refining slag
Inventor: ANEZAKI MASAHARU
IPC: C21C5/36
Filed: 1994-05-18
Abstract: PURPOSE:To reduce and extract the phosphorus in slag into a iron bath and to effectively utilize the slag by burning a carbonaceous material with an oxidative gas in the molten iron bath to melt refining slag and stirring the iron bath and the slag. CONSTITUTION:The refining slag 14 is housed together with the molten iron bath 12 in a vessel, such as regenerative furnace 10. The carbonaceous material, such as coal powder, and the oxidative gas, such as gaseous O2, are supplied via tuyeres 16 or a top blowing lance 18 into this regenerative furnace 10. The carbonaceouse material is burned in the iron bath 12 or on the surface of the bath to melt the slag 14 and to reduce and extract the phosphorus in the slag 14 into the iron bath 12. At this time, the iron bath 12 and the slag 14 are stirred to increase the reaction rate by the generated gaseous CO and or the stirring gas, such as gaseous N2, blown from the tuyeres 16. The low-phosphorus gas obtd. in such a manner is reused as the slag for refining iron and steel. On the other hand, the iron bath in which the phosphorus is absorbed is utilizable as a substitute for phosphorus ore. The phosphorus-enriched slag is obtd. by repeating the reduction and extraction described above, by which the perfect recycling of the slag as resources for phosphorus fertilizers, etc., is made possible.

Title: Optical zero-phase current transformer
Inventor: TAGO MAKOTO
IPC: G01R31/02
Filed: 1988-04-27
Abstract: PURPOSE:To improve the detecting sensitivity of a zero-phase current to a large extent, by shielding the outer surface part of a magnetic core with a magnetic shield member which is formed by laminating high-permeability magnetic materials having the different operating magnetic fields. CONSTITUTION:Magnetic fields are generated by three positive-phase currents through three-phase conductors which are provided through the inside of a zero-phase current transformer 1. The magnetic fields are attenuated through magnetic shielding layers gradually from the outside. The magnetic fields reaching a magnetic core 5 become very small. Meanwhile, when the zero-phase current flows through any one of the three-phase conductors due to the occurrence of a grounding fault, magnetic flux is induced in the magnetic core 5. A coil 6 detects this fact and sends a signal to an optical voltage sensor 4. The optical voltage sensor 4 detects the signal highly sensitively without induction and outputs an optical signal.

Abstract: PURPOSE:To obtain a stable zero crossing pulse as a comparison output, by stopping the discharge of an integral network for obtaining the temperature signal voltage, in the period for generating a zero crossing pulse for comparing the temperature signal voltage and the temperature setting voltage. CONSTITUTION:A transistor TR24 of a discharge stopping circuit 25 is turned on through a resistance 26 when a zero crossing pulse Vz is not generated from a zero crossing pulse generating circuit 17. On the other hand, the pulse Vz is generated, and in the period for comparing the temperature setting voltage Vs and the temperature signal voltage VT, the TR24 turns off, and stops discharge of a capacitor 13 of an integral network 15.
