ABSTRACT:
The invention relates to a method of reheating, storing and conveying metal bars or rounds cast by continuous casting processes whereby uniform bar temperature is achieved, lengthwise and cross sectionally, prior to rolling, cutting and other secondary operations, and discloses apparatus for practicing the novel process concepts. Cast metal bars having varying heat content throughout their length and cross section have their local heat content restored by heaters at a variable rate proportional to the energy required to produce a substantially uniform temperature throughout the bar length end cross section. The reheated bars are stored in a inventory control and soaking furnace for a duration at least sufficient to permit the energy absorbed by the bars during reheating to uniformly dissipate throughout the bars, and and bars of uniform temperature are released from the furnace at a controlled rate for subsequent processing. The method and apparatus of the invention permits uniformly heated bars or rounds to be released and conveyed at controlled and uniform intervals for secondary operations even though the casting production rate is non-uniform and not synchronized with the secondary bar processing operations.
