Inventor: SHIMIZU MASAMI
IPC: B22D41/005
Filed: 1986-01-31
Abstract: PURPOSE:To prevent the erosion of the refractory body at the hot spot part of an LF ladle by blowing an inert gas from a porous plug while under refining a liquid metal with its heating. CONSTITUTION:A molten steel 6 and slag 7 are melted in an LF plate and the heating is performed by an electrode 4 with blowing an inert gas from the lower part porous plug 5.

Filed: 1984-02-06
Abstract: PURPOSE:To make buffer memory accumulating input data unnecessary by recording (reproducing) data in bubble memory by writing continuous data having a variable speed at every bit and dummy bits in bubble memory and a defective loop, respectively. CONSTITUTION:When an input clock is sent to a drive part 1 based on a command E, a drive magnetic field of a bubble memory 2 is caused to be rotated, and data are recorded. Then defective loop information D is received from a memory 3, and its contents are investigated. If the contents of the memory 3 are zero, an input is waited until the next clock.
