Desulphurization of the high-alloy and middle-alloy steels under the conditions of an EAF by means of synthetic slag based on CaO-Al2O3
Karel Michalek, Libor Čamek, Karel Gryc, Markéta Tkadlečková, Tomáš Huczala, Vladimír Troszok
Strokovni članek
Oznake: steel;desulphurization;synthetic slag;basicity of slag;
The article deals with the results of the experimental heats performed in the electric steel plant of TŘINECKÉ ŽELEZÁRNY, a. s. (TŽ, a. s.). The aim was to verify the possibility of deep desulphurization of steel in the basic 10-t electric arc furnace. Experimental procedures making use of the indus ...

A study of the high-temperature interaction between synthetic slags and steel
Karel Gryc, Karel Stransky, Karel Michalek, Zdeněk Winkler, Jan Morávka, Markéta Tkadlečková, Ladislav Socha, Jiří Bažan, Jana Dobrovská, Simona Zlá
Strokovni članek
Oznake: synthetic slag;stell;interaction;saturation;
The paper is devoted to selected aspects of the current issues of the high-temperature interaction of the synthetic multicomponent oxidic systems and selected grades of steel. Analysing the consequences of the interaction between slag and molten steel is an integral part of modern research that can ...

Ladislav Socha, Jiří Bažan, Karel Gryc, Jan Morávka, Michal Pivko, Petr Styrnal, Václav Pilka, Zbygněv Piegza, Karel Michalek, Markéta Tkadlečková
Strokovni članek
Oznake: steel desulphurization;slag;fluxing agent;corundum;secondary metallurgy;steel;
This paper presents the experience obtained from plant experiments specialized in the usage of three types of fluxing agents for slags based on Al[sub]{2}O[sub]3. Proper experiments took place during the steel treatment by secondary metallurgy. The objective of the plant experiments was to assess th ...
