Title: Device for supporting roll in continuous caster
Inventor: UESHIMA YOSHINORI
IPC: F16C33/34
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To prevent the development of flaking even in the case of developing the difference caused by thermal expansion of a roll and to extend the service life of the whole apparatus by using cylindrical roller bearing to the bearing positioned at the passage of a cast slab and using the bearing for supporting loading to the axial direction of the roll and fixing while deciding the position of the roll to the bearing positioned at out of the passage. SOLUTION: Mutually adjacent sides (free sides) of a long and a short rolls 16 concentrically arranged in a roll supporting device, are supported with the cylindrical roller bearings 10 to both. The opposite sides of the long and the short rolls 16 are supported with automatic aligning roller bearings 11. These bearings are acted so that the elongation caused by thermal expansion of the rolls 16 is set free to the inside while fixing to the outside as the fully reverse way as the conventional way. Since the roller and the inner and the outer rings in the cylindrical roller bearing 10 are brought into linear contact and the peripheral speed is the same speed over the whole length of the roller, the slipping friction is difficult to develop and the flaking is not developed.  Further, even if the automatic alignining roller bearing 11 is substituted into the cylindrical roller bearing or a double row conical roller bearing, any trouble is not developed.

Abstract: PROBLEM TO BE SOLVED: To cancel an alarm display state more appropriately by considering the driving condition of a stepping motor where the stepping motor is driven for a fixed amount of time by a normal drive pulse with a certain capacity as well as the voltage of a secondary battery, and canceling the alarm display state. SOLUTION: An oscillation circuit 4 outputs a signal with, for example, 32,768 Hz due to the vibration of a crystal vibrator. A dividing circuit 5 divides the signal and outputs it to a needle-handling pulse creation circuit 6 and an alarm display control circuit 8. The creation circuit 6 creates a normal drive pulse and a correction drive pulse and outputs them to the control circuit 8. A voltage detection circuit 3 detects whether the voltage of a secondary battery 2 is equal to or less than 1.2 V or exceeds 1.3 V and outputs the obtained information to the control circuit 8. A normal drive pulse is amplified by a drive circuit 9, is outputted to a coil 12a of a stepping motor 12, and rotates a coil 12b.  A detection circuit 3 judges that voltage of the battery 2 is equal to or less than 1.2 V and transfers the result to the control circuit 8, and the circuit 8 performs output with an interval that differs from each 1 second for the interval of the handling of the needle of the drive pulse, and displays a warning by 2-second handling of the needle.
