The new advanced quench-and-temper facility (AQTF) heat-treatment line supplied by SMS group to TimkenSteel at its Gambrinus Steel Plant in Canton, Ohio, commenced full commercial production. Extensive testing was successfully completed in November 2017. The line is able to treat 10 tons per hour of bars and heavy-walled tubes up to 13 inches in diameter.
The compact line is characterized by a combination of induction preheaters and combustion furnaces for austenitizing and tempering processes. Subsequent cooling takes place in the newly developed quenching shell, an advanced OD/ID water sprayer, characterized by high-quench severity.
