TEMPCORE®, the most convenient process to produce low cost high strength rebars from 8 to 75 m


The "Tempcore" process, a quench and self-tempering process initiated in the seventies, is designed for the manufacturing of high quality concrete reinforced bars. A specifically adpated cooling box is located near te exit of the finishing stand to quench the bar surface with a high cooling rate during a limited time. The thickness of the external layer is transformed in a hard martensitic phase, later reheated and tempered by the core of the product during the final slow cooling. This process is largely implemented in the World with more than 80 licenses mainly located in Europe, Asia and India.
