A continuous caster in a steel plant relies on precise electrical control to maintain the integrity of molten metal flow, while a rolling mill in the same industry uses the same part to ensure consistent pressure application during steel shaping. The NUMTEC-INTERSTAHL injection current source modulates electrical energy to drive critical actuators and hydraulic systems within industrial machinery. In the steel industry, it is commonly installed in hydraulic presses, forging machines, and automated handling systems where controlled current delivery is essential for accurate and repeatable operation. This device enables the precise regulation of hydraulic and pneumatic systems, ensuring stable performance in high-stress environments. Its role is vital in maintaining the efficiency and safety of production lines that require reliable power distribution. In secondary applications, it also supports equipment in metal forming and cutting operations where consistent electrical output is necessary for tool engagement and material processing. The part’s integration into these systems ensures that critical processes remain uninterrupted, supporting the continuous operation of steel manufacturing facilities.
