Abstract
The roll and roller has a core with a threaded on sleeve of differently radially high threads such that the crown or head of one thread reaches the bottom/foot of the thread groove way of the other, but not vice versa so that a spiral channel is established while the abutting foot/crown configuration is welded indirectly as a weld layer is deposited onto the outer surface of the sleeve.
Claims15
Support and transport structure including a roller or roll in a machine for continuous casting, the roller or roll having a core and an outer sleeve, there being a threaded connection between them, the structure further comprising:
- an entire outer portion of the sleeve being a weld-deposit layer;
- said core having an outer threadway with crowns and roots of a particular height, the sleeve having an inner threadway with crowns and roots of a height different from the particular height, the core being threaded into the sleeve so that the crown of one of said inner and outer threadways abuts the root of the other of said inner and outer threadway so that a spiral channel results between the crown of the other threadway and the root of the one threadway;
- the respective abutting crowns and roots being intimately bonded together on account of the placement of said weld deposit layer having caused heat to migrate into zones of the abutting crown and root resulting in a weld bond between the abutting crown and root;
- said core having a central bore;
- bearing pins inserted respectively from opposite ends into the central bore for journalling the roll or roller, there being a gap between the pins and the bore;
- mounting means for stationarily mounting said pins;
- and
- duct means in the pins to conduct coolant to and from the gap and the channel.

- mounting means for stationarily mounting said pins;
- and
- duct means in the pins to conduct coolant to and from the gap and the channel.
