Title: Method and device for removing slag in oxygen steel making converter
Inventor: NAKANISHI KIYOUJI
IPC: C21C5/46
Filed: 1982-07-06
Abstract: PURPOSE:To improve the yield of iron, by flowing slag once into an auxiliary vessel to increase the layer thickness of the slag and to make the skimming easy and returning metal again to a converter, in the stage of skimming. CONSTITUTION:A vessel 2 which is opened at the top and has an axial center intersecting approximately orthogonally with the axial center of the furnace 1 is stuck in the port part of a converter 1 by bringing the opened surface at the top thereof into contact with the edge on the counter tapping side of the port 6 of the furnace 1. The furnace 1 is first tilted to admit the dephosphorized slag floating on the bath surface of the molten iron 3 in the furnace 1 into the auxiliary vessel 2. Since the depth of the slag 4 in the vessel 2 is large, the slag can be easily ladled away by a siphon type slag remover or the like. If the furnace 1 is returned perpendicularly thereafter the iron 3 flowed out into the vessel 2 is returned again into the furnace 1. The successing oxidation refining is thus started immediately, and the loss of the iron 3 in the stage of skimming of the converter 1 is reduced considerably.

Abstract: PURPOSE:To enhance starting characteristics and the engine operating perfor mance by shutting off once the current to a suction gas heating means at the time of cold start, beginning current supply when it is judged that the rate of increment of the revolving speed has exceeded a certain level, and thereby enhancing ignition characteristics of the later part of continued combustion period.

Abstract: PURPOSE:To obtain an output signal having a constant pulse width independently of the pulse width of an input signal by forming a delay circuit with one inverter inverting an input signal and retarding the trailing time of a trailing edge of the inverted input signal. CONSTITUTION:An inverter 2 consists of a P-channel MOS transistor(TR) 3 and an N-channel MOS TR 4, inverts a pulse signal S1, retards the trailing time of the trailing edge to give an inverted signal S2 to other input terminal 1b of a two-input NAND circuit 1. That is, the inverter being a component of the delay circuit inverts the input signal and retards the trailing time of the trailing edge of the inverted input signal. Thus, the pulse width of the output signal is set in a time when the output signal of the inverter is changed up to the logic input inverting level of a comparator circuit.
