The secondary lance is the primary equipment for computer‑based dynamic control of the converter.
The secondary lance is the primary device for computer‑based dynamic control of the converter. It consists of a water‑cooled, three‑layer steel pipe and is equipped at its lower end with an electrode holder that accommodates probes for temperature measurement, carbon determination, oxygen measurement, and liquid‑level sensing. By integrating with the metallurgical model, it enables automated control of the smelting process.
