A billet pushout system is provided for an electric induction billet heating line with long length revolute jointed pushout rods forming a non-jamming pushout rod assembly that is stored in a linear enclosure connected to an arcuate enclosure that deploys and retracts the pushout rod assembly to and from the electric induction billet heating line.
SYSTEM AND METHOD FOR HEATING METAL BLANKS
A method of adjusting a position of a blank entering a furnace includes measuring a position of a heated blank exiting the furnace, recording one or more offset values from a nominal value of the heated blank exiting the furnace, calculating a revised position of a subsequent blank entering the furnace as a function of the one or more offset values, and adjusting a position of the subsequent blank entering the furnace as a function of the one or more offset values. The position of the heated blank exiting the furnace can be measured with an electronic vision system, a robot can adjust the position of the subsequent blank, and offset value(s) can be an elapsed furnace operation time, a number of heated blanks that have exited the furnace, and a physical dimension between an actual position of the heated blank and the nominal value of the heated blank.
