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.

Systematic Analysis of the Submerged Lance
With the vigorous development of China’s steel industry, the country not only maintains its position as the world’s largest steel producer but has also seen a steady increase in the domestic production rate of specialty steels. Steel plants have made significant strides in automating their steelmaking processes, with Baosteel and Wuhan Iron & Steel having successively achieved “one‑button” steelmaking capabilities.
