IPC: C21C5/46
Filed: 1983-08-05
Abstract: PURPOSE:To surely separate slag without returning the position of converter vessel and further to prevent the slag in vessel from flowing outside the cooler, by a method wherein just before flushing of slag, the steel transportation truck is transferred from the position for tapping and at the same time, the slag receiving truck is moved to the position for tapping. CONSTITUTION:To steel transportation truck 6 is transferred to the position for tapping of converter 3 and the furnace 3 starts tapping steel into the steel ladle 5 by tilting it. After about 1-2min from the start of tapping, the slag receiving truck 2 is moved near the steel transportation truck 6. As that time, slag receiving truck 2 is waiting at the position so as to lessen the clearance between the ladle 5 and the cooling container 1. Then, just before the slag starts to be mixed into molten steel at the end period of tapping and otherwise, at the same time when the slag starts to be mixed into molten steel, slag is flushed into the container 1 by simultaneously or individually operating and moving the trucks 6 and 2. At that time, it is not necessary to return the position of the vessel of converter 3 and the tilting angle of converter at the end period of tapping is kept. Though the position of converter 3 is returned to the original position after completing tapping steel, the cooling container 1 at that time is so positioned that the slag on returning does not flow outside the cooling container 1.

Title: Cooling device of superconductive coil
Inventor: KURODA KUNISHIGE
IPC: H01L39/04
Filed: 1984-07-12
Abstract: PURPOSE:To enable a forced-cooling system superconductive coil to cool effectively in a short time by a method wherein a coolant path for heat-exchanging which has a smaller flow resistance than a flow resistance of a coolant path inside a conductor is installed and the means to control coolant flow in the coolant path for heat-exchanging is installed. CONSTITUTION:When a coolant 6 from a coolant supply source is sent by pressure with a valve 9 open at the time of initial cooling stage, almost whole coolant 6 is flowed into a coolant path 8 for heat-exchanging and the coil 5 is cooled indirectly, as the temperature of the coil is high and the flow resistance is large. Accordingly, as the temperature of the coil 5 falls and the flow resistance becomes small gradually, the coolant 6 turns to branch to even cooling path 4 side inside the conductor, thus cooling is accelerated. When the coil 5 is enough cooled, the temperature thereof reaches to 50-100K, the valve 9 is closed and the whole coolant 6 is flowed through the coolant path 4. As the result, the temperature of the coil 5 is rapidly fallen and the coil 5 can be turned on conductive that is, superconductive state is attained.
