The research on ladle metallurgy can be dated back to early the 1970s and was carried out by Professor Julian Szekely and coworkers. After 60 years of development, the secondary refining of liquid steel has developed with the evolution and demand for high-quality and clean steel production.
Non-ferrous metallurgy is the science that investigates how to separate associated elements from non-ferrous metal ore, concentrate, secondary resources, or other materials, so as to produce non-ferrous metals or their compounds. The 113 elements discovered include 88 metals, 9 semimetals, and 16 non-metals.

Ferrous metallurgy is a subject which conducts research with iron ore or recycled iron resources as main raw materials to combine into the materials of production steel and iron with multiprocess cooperation through the processes including melting, slagging, smelting, refining, solidification, and plastic working.
Ladle furnaces. The first step of the secondary metallurgical treatment takes place in two ladle furnaces. During this phase a rough setting of the chemical analysis occurs as well as a further heating-up of the liquid steel.
