M-tec wire GmbH is a part of the group m-tec. The group, with head-office in Töging am Inn and production facilities in Voerde, Germany, is specialised in additives for the steel mills and foundries and cored wires. m-tec wire is the business unit specialised in cored wires. We provide a complete range of injection core wires to the global steel industry and foundries: CaSi, CaFe, FeNb, FeTi, FeB, S, C…
Our focus is on high performance cored wires for Calcium treatment:
- Max-Cal®: welded thick sheath pure Calcium cored wire produced with extruded Calcium rod
Sufficient quantity of Calcium has to be added, with good calcium distribution in the melt, to avoid that high-melting-point calcium aluminate inclusions remain in the steel. If this is not the case, the aluminate inclusions remain solid at steel making temperatures and may affect casting and rolling performance as well as the steel properties. The Calcium shall be added progressively to reach a ratio 12 CaO-7 Al2O3 to modify the solid inclusions into liquid state with lower melting point (ca. 1400 °C).
M-TEC WIRE will provide sufficient technical support and optimize your Ca injection practices with well experienced technical support team.
