Plasma process

A cutting head hurriedly makes its way across sheet metal, cutting out samples at speeds of up to 2,500 millimeters per minute. The state-of-the-art cutting unit for the acceptance test accomplishes its job using a plasma process that melts the steel by heating it to approximately 30,000 degrees Celsius.

Another impressive feature is the high degree of automation; every step in the job is automated, from inserting the sheet metal and labeling it to ejecting the finished sample. Cutting takes place under water to keep emissions low and to prevent the sample from getting warped.

Before they go to the customer, the coils are tested at thyssenkrupp Steel to ensure they have the mechanical properties specified in the order, including yield strength, tensile strength, and notch impact energy. The acceptance testing team conducts approximately 25,000 tests per month. Individual labeling prevents each sample from being mixed up with the others. The new unit has shortened the lead time significantly, thereby enabling orders to be delivered to customers sooner and improving how we handle deliveries. The ability to determine parameters quickly is also advantageous when creating and developing new materials.
