IPC: C21C5/46
Filed: 1988-11-17
Abstract: PURPOSE:To efficiently refine a molten steel and to prevent the erosion of refractories in a converter by providing an electromagnetic stirrer to the outside of the furnace body in the inside part of the converter where the molten steel exists and circulating the molten steel. CONSTITUTION:Holes are bored to the shell at plural circumferential points in the lower part of the converter body and coils are embedded thereon. The electromagnetic stirrers 5 to move the molten steel upward are mounted to the coils. Oxygen is blown from a top blowing lance 2 and quicklime is simultaneously charged through the throat into the converter to dephosphorize the molten steel at the time of blowing. Such circulating flow that the molten steel falls is induced in the central part of the furnace by the electromagnetic stirrers 5 at this time, by which the molten steel is sufficiently stirred. The flow of the molten steel toward the furnace wall is eliminated and the erosion of the furnace wall retractories is prevented.

Filed: 1988-11-19
Abstract: PURPOSE:To annunciate it when a broadcast whose reproduction is disabled is received by annunciating the reception of a reproduction disabled radio wave on the condition that an intermediate frequency signal level is a prescribed value or over and the normal reproduction signal of video or audio signal is absent. CONSTITUTION:A conventional satellite broadcast reception circuit is provided with an annunciation circuit 7. There might be a case that a broadcast station of a channel selected by the 2nd converter circuit 2 makes any broadcast but it cannot be reproduced by a satellite broadcast receiver.
