“…It is known from the literature that some evaporation losses of approx. 10–20% occur for phosphorus in commercial SiMn production . A limited additional refining effect is therefore achieved.…”

The industrial production of high manganese steel melts with approx. 10-30 wt% Mn makes high demands on the utilized Mn-bearing alloying agents in terms of chemical composition and cost-efficiency. Conventional Mn-bearing alloying agents are reviewed in this regard. A modified process route has been conceived for pyrometallurgical winning of special silicomanganese grades tailored for high manganese steelmaking. For each individual process step, namely manganese slag production, silicomanganese production, and optional desiliconization of silicomanganese, results of lab-scale experiments are discussed.

“…As barium compounds are more expensive, whereas those of calcium are more available, the slags based on CaO-CaF 2 are now mainly considered [1]. Especially the production of FeMnHC in blast furnaces contributes to high phosphorus content [2][3][4][5]. In consequence the further treatment of the prime material to the grades with medium and low carbon contents meets the same task, namely the reduction of phosphorus to contents below 500 ppm.…”

Phosphorus in steelmaking processes is a harmful admixture and at every stage of the production of steel must be removed from the melt. One of the sources are ferroalloys, which are used to introduce alloying element for steel. The paper presents method of dephosphorization of high and medium carbon ferromanganese using mixture based on CaO-CaF 2 , containing in its composition CaSi and CaC 2 . The experimental heats were conducted in an induction furnace with the capacity of 20 kg, in temperature about 1450 °C. While the dephosphorizing mixture was being added, a stream of argon was being injected into the metal bath. Dephosphorization efficiency raged from 21 to 42%. This work has been shown the relationship between dephosphorization, and the amount of inert gas and initial concentration of phosphorus in ferromanganese.
