Title: Method for preventing clogging of submerged nozzle for continuous casting
Inventor: MIZUKAMI YOSHIMASA
IPC: B22D41/50
Filed: 1995-03-17
Abstract: PURPOSE: To prevent a nozzle from being clogged by providing a plurality of holes whose diameter is not greater than the inner diameter of the submerged nozzle in the refractory to which the inclusions are attached to make the position of the holes variable, and feeding the molten steel passing through the holes to the submerged nozzle. CONSTITUTION: Holes 3, 4, 5 whose diameter is not greater than the inner diameter of a submerged nozzle 10 are provided in the refractory 2 to which the inclusions are attached. The molten steel 6 is fed to the submerged nozzle 10 through the hole 4. The inclusions are attached to the hole 4 and removed, and the molten steel 6 with small amount of the inclusions 12 is fed to the submerged nozzle 10. No inclusions 12 are attached to the submerged nozzle 10, and clogging is not generated. A lot of inclusions 12 are attached to the hole 4, and then the flow rate of the molten steel 6 is reduced, the refractory 2 to which the inclusions are attached is moved to the position of the hole 3 to achieve the switching to the new hole 5. This realizes the improvement of the quality of the slab, and the stabilization.

Filed: 1989-03-15
Abstract: PURPOSE:To improve a working accuracy by constituting a grinder so as to feed a moving body in a trace quantity with the reaction force generated at the time of actuation of an exciting part. CONSTITUTION:In the case that a moving body 2 is positioned with its screwing in a direction A, for instance, when a residual feeding in a small amount is generated because of the observation value of the moving body 2 being not filled against the feeding quantity found from the azimuth of a motor 3 by the backlash and deflection of a feeding screw 4, a detection part detects this residual feeding to transmit a contracting actuation signal to a piezoelectric element 51, which is abruptly elongated. When the piezoelectric element 51 is elongated and a weight 52 is moved in a direction B, the reaction is propagated to the moving body 2, this reaction eliminates the backlash and deflected of the feeding screw 4 and executes the trace quantity feeding of the moving body 2. After completion of the trace quantity feeding, when the moving body 2 does not fill the feeding quantity of the motor 3 side, the screw feeding stage of the motor 3 and a trace quantity feeding stage are repeatedly performed until the feeding quantities of the both coincide.
