Title: Cleaning method of molten steel
Inventor: NISHITANI TERUYUKI
IPC: C25C3/34
Filed: 1984-04-14
Abstract: PURPOSE:To improve a cleaning characteristic by immersing an anode having an oxygen ion-conductive refractory material on the surface into a molten steel which acts as a cathode, impressing a voltage thereto and passing the oxygen in the molten steel through the oxygen ion-conductive refractory material. CONSTITUTION:The anode is constituted of an electrode bar 5 and a molten metal 6 which is easily reactive with oxygen ion or gaseous oxygen. Such anode is immersed into the molten metal 12 via a zirconia refractory layer 7. On the other hand, a cathode is formed of the molten steel 12 itself through the electrode bar 4. The oxygen ion from the molten steel 12 passes through the layer 7 and reacts with the molten metal 6 when a voltage is impressed between both electrodes by turning on a switch 11 and regulating a resistor 10. The oxygen in the molten steel 12 is removed by the above-mentioned method and the non- metallic inclusions are gathered to the layer 7 and are thus removed, by which the molten steel 12 is cleaned up.

Abstract: PURPOSE:To eliminate occurrence of the potential fluctuation at the output terminal even with such reason that the constant current property is not good for the constant current source contained in the differential amplifier. CONSTITUTION:Constant current source 11 is connected to the emitter side of transistor T1 and T2 each possessing input terminal 1 and 2, and the collector side is connected to the power source. At the same time, the collector side of transistor T3 is connected to the output end of source 11, and the base of T3 is connected to connection point 14 of resistance 7 and 8 which are connected in series between output terminal 3 and 4 with the same value.
