Title:
DEVICE FOR CHANGING CASTING WIDTH OF TWIN-BELT CONTINUOUS CASTING MACHINE
Document Type and Number:
Japanese Patent JPS6049841
Kind Code:
A
Abstract:

PURPOSE: To change mechanically casting width without the aid of manual labor by driving respectively synchronously a pair of right and left dam guide bars and dam guide assemblies by motors to expand or contract the same.

CONSTITUTION: Slide holes 15 provided with bushings 14 in which a shaft 11 is passed are formed in the lower part of dam guide assemblies 10, 10. Both assemblies 10, 10 slide with respect to the shaft and the space of dam blocks 7, 7 is adjusted to various widths. Two points are required for each one dam guide bar to change the width of dam guide bars 9 in order to stabilize the moving attitude and therefore four driving motors 31 are required. The changing width of the dam guide bars 9, 9 and the changing width of the assemblies 10, 10 correspond to each other and therefore the driving motors 31, 21 are controlled by an electrical circuit so as to be driven at the prescribed corresponding revolving speed by receiving the signals from detectors 34, 24 for revolving speed.
