IPC: B22D11/05
Filed: 1983-11-14
Abstract: PURPOSE:To perform drawing at a high speed without generating breakout, rough surface, etc. in the stage of starting drawing by setting the angle of inclination of the mold piece at the point of the time for starting drawing smaller than the ordinary drawing angle and setting the same at the ordinary drawing angle after casting for a prescribed length. CONSTITUTION:The angle of inclination of the mold piece at the point of the time for starting drawing of casting is made smaller than the ordinary drawing angle in continuous casting of a steel in which a continuous casting mold of the type variable in the angle of inclination is used. Drawing is thus started under the decreased static pressure of the molten steel, the decreased frictional force for drawing and the decreased tensile force acting to the hook part of a dummy bar. The angle of inclination is set at the ordinary drawing angle and the ordinary operation is started when the casting length attains a prescribed length. The temp. of the billet at the end of the continuous casting machine in the initial period of drawing is made higher by the above-mentioned method. As a result, a direct feed rolling reduction rate is increased and the effect of energy economization is improved.

IPC: B23K9/073
Filed: 1997-07-23
Abstract: PROBLEM TO BE SOLVED: To provide a power source equipment for direct current arc welding of high power rate by equipping a series circuit which consists of the primary winding of the transformer connected with the commercial alternating current power supply and both waves rectifier circuits, a switching element which short- circuits the output of both waves rectifier circuits, and the both rectifier circuits for the output which rectify the output of the secondary winding. SOLUTION: In the period of a half wave of the polarity in which the current flows from the commercial alternating current power supply 1 to the primary winding T21p, when the switching element TR10 is electrified, the current which is proportional to the instantaneous value of the voltage waveform of the AC power source 1 flows to the primary winding T21p of the transformer T21. In the normal course of operation, the diode D22 is in the condition of the reverse bias because the terminal voltage of the condenser C11 is charged higher than this induced voltage, and so the current does not flow. The voltage of the reverse polarity is induced in the secondary winding, when the switching element TR10 is cut off, and charged in the condenser C11 through the diode D21.  At this time, the induced voltage exceeds the terminal voltage of the condenser C11 without relating to the size of stored energy.
