Title: Vertical type continuous casting installation for slab having large section
Inventor: SOEJIMA TOSHIYUKI
IPC: B22D11/12
Filed: 1985-03-18
Abstract: PURPOSE:To cast a slab having a large section and good quality by providing electromagnetic stirrers which stir the unsolidified part in a slab descending from a casting mold and stirring said part at the height at which the residual molten steel rate attains an optimum value. CONSTITUTION:The molten steel is poured from a tundish into the casting mold 2 and a dummy bar 3 is fixed to right under the mold 2 to wait for the solidification of the molten steel. The dummy bar 3 is lowered and support rolls 5, 6 are driven and rotated by the slab 1 to support the slab 1 from both sides when the residual molten steel rate in the mold 2 attains about 30%. The in-roll electromagnetic stirrer 5a incorporated into each support roll 5 is started to stir the unsolidified part 1a in the slab 1 at the same instant when the bar 3 starts descending. All of the stirrers 5a are not simultaneously driven but only the stirrers 5a occupying the optimum stirring position are selectively driven according to the descending of the slab 1 in this case.

Abstract: PURPOSE:To control a gas quantity fed into an air bag to be always proper by forming an openable/closable gas passage which connects a gas generating device for air bag to the outside of the air bag and opening the gas passage at the time of the rise in temperature of atmosphere. CONSTITUTION:When the temperature in the casings 12, 14 of an inflator 10 is below a defined value, since the first spring 36 composed of a shape memory alloy of a valve 20 is not deformed, it is balanced with a second spring 38. Hence, as a piston 34 is in an ordinary position closing an introducing port 40, a gas passage from the introducing port 40 to a discharge port 32 through the inside of a cylinder 24 is closed. On the other hand, when the temperature in the casings 12, 14 becomes above the defined value, since the first spring 36 is deformed, a piston 34 is moved against a second spring 38 opening the introducing port 40. As a result, part of gas generated by the inflator 10 at the time of the collision of a vehicle is discharged out of the discharge port 32.
