ABSTRACT:
In a continuous casting and rod rolling system, the production rate is generally limited by the capacity of the slowest element. The present invention is directed to changes in the rod coiling station portion of the system, and particularly to modifications to the flyer tube and loop forming portions which enable higher production capacity. According to these changes, the prior art flyer tube is shortened to eliminate the constant radius end portion thereof, and the circle forming function is performed by adding an annular cylinder coaxial with the flyer tube axis to shape the rod into a nearly perfect circle. The flyer tube according to the invention has a continuously changing angular relationship from its axis; the curved longitudinal path of the tube redirects rod from its vertical path to discharge the rod from the flyer tube in a generally horizontally direction. The circular loop forming cylinder forms the rod into circular loops which fall freely from the cylinder onto a turntable surface.
