Heat treatment of steel is crucial for the material properties of the final products. Two steps are important in this process: annealing, and hardening and tempering.
For the annealing of special grades and for spheroidise annealing CDW uses HICON batch-type annealing furnaces by Ebner, which were conjointly developed with the manufacturer and are specifically designed to meet the requirements of our company. With these batch furnaces, spheroidise annealing with temperatures of up to 850 degrees is possible.
As an alternative to the more static batch annealing we also have continuous annealing lines for treating cold rolled high carbon steel strip. Thus individual and special property combinations can be achieved.
The entire heat treatment procedure is controlled by means of modern process management, which leaves nothing to chance. The material reaches the necessary treatment temperature in the shortest possible time or in fine-tuned steps. In any case, process management controls heating and cooling in an absolutely exact and reliable manner.
CDW has five wide strip and three narrow strip lines for the hardening and tempering of steel strips. They are used for hardening and tempering of heat-treatable steel, spring steel and non-corroding martensite steel grades.
Electrical steel strip is treated in two continuous annealing lines, and the strip is heated up to temperatures of more than 1,000 degrees centigrade. Varnishing equipment for surface coating is integrated in these lines.
