Title: Method for controlling solidification segregation of continuous casting steel ingot
Inventor: UEJIMA YOSHIYUKI
IPC: B22D1/00
Filed: 1984-12-28
Abstract: PURPOSE:To control effectively solidification segregation, more particularly the overlap segregation among trees in the stage of solidification and to obtain a product having good quality in continuous casting of a carbon steel having a specific value or below of C concn. by adding a prescribed ratio of Mo into the molten steel. CONSTITUTION:Mo is added at <=2wt% into the carbon steel contg. <=0.53wt%C in continuous casting of said carbon steel. The delta phase (=alpha phase) region in the phase diagram of the carbon steel is thereby expanded. In general, the diffusion speed of the impurities or additive element in solid iron is 10-100 times larger in the delta phase than in the alpha phase. The diffusion speed from the segregated part of a high concn. to the low concn. part at the periphery increases correspondingly and the solidification can be decreased when the quantity and presence time of the delta phase increases in the solidification process of the steel. The delta phase region in the dendrite part increases when the alpha stabilizing element such as P is added to the steel. As a result the co-existence region of the delta phase and alpha phase increases and the sepn. of the alpha, gamma (e.g., Mn) stabilizing elements is accelerated, by which the overlap segregation among trees is decreased.

Abstract: PURPOSE:To prevent secondary failure upon occurrence of ground fault by detecting voltage across a filter capacitor and interrupting a circuit breaker if thus detected voltage does not exceed a reference level upon elapse of a sufficient time after start of charging of the filter capacitor. CONSTITUTION:Under a state where a filter capacitor 8 is not yet charged and the voltage Vf across the filter capacitor 8 is lower than a reference level Vfr while the overhead line voltage Vd is normal and higher than a reference level Vdr, a high speed circuit breaker 4 is turned ON by a high speed circuit breaker ON signal ION to start charging of the filter capacitor 8. When a detection signal Vf of a capacitor voltage sensor 14 does not exceed the reference level Vfr because of ground fault, frequency signal of a logic circuit 33 remains in H level even upon elapse of a delay time and a high speed circuit breaker OFF signal IOFF is outputted from a delay circuit 34. Consequently, the high speed circuit breaker 4 is turned OFF to interrupt current flow to the grounded part thus preventing secondary failure such as burning of charging resistor RC or breakdown of grounded part.
