During 1994, the Timken Co. upgraded the rotary hearth billet furnace at the Gambrinus plant. As part of the upgrade, a new furnace supervisory control system was installed. This system includes an on-line thermal model which calculates steel temperatures and gradients while accounting for changing project dimensions and steel grades. Temperature and production rate set points are calculated to consistently produce properly heated pieces. The set point control strategy will reduce fuel consumption, decrease temperature variations between pieces, prevent overheating, and minimize the amount of scaling and decarburization of the steel.
