3. Add calcium or calcium silicon wire as needed. 4. Stir the bath enough to keep an eye open on top of the ladle. 5. Wire inject the cored wire (100) containing oxides of iron to get the dissolved oxygen up to 5 to 1000 parts per million. 6. Take the heat the
The effective modifiion of spinel inclusions by Ca treatment in …
calcium treatment is possible, and it is even suggested that the modifiion of spinel inclusions by calcium treatment would be easier than alumina inclusions.3,6–8 The work reported in this paper is consistent with these findings, and it will show that complete
Production Technology of Cored Wire Used for Liquid …
Production Technology of Cored Wire Used for Liquid Metal Treatment in Steel Plants: Part Five Abstract: The tool designer uses flower pattern design software to develop the successive stages of work and the design of the CW forming unit (for different profiles different sets of tooling is required).
m-tec wire GH - High Performance Wires
Three major factors of the product design strongly affect the metallurgical performance of Calcium wires: · The thick sheath allows injecting the wire deep enough into the ladle where sufficient ferrostatic pressure is generated by the steel column to keep the Calcium liquid at steel making temperatures.
The calcium level attained at Ladle Furnace with above addition rate after pure calcium cored wire treatment is 1530 ppm. It may be noted that the optimization of wire feeding speed is necessary for achieving the best recovery. The calcium recovery values
between injection and core wire (1) Calcium and calcium alloys cored wires are derivated from the welding techno- logy. Such wires are developed with feeders, generally, for treatment in full ladle (2), in bottom pouring (3) , in tundish of casters (5) , (6). The study

Calcium Carbide – Minex
Calcium carbide reagents are granular sized materials used in the steel industry for specialized processing of steel. These products are added to liquid steel both during and after the melting stage and acts as powerful desulphuriser and deoxidizer during ladle treatment.
MacSphere: Modeling of inclusion evolution in Ladle …
During ladle treatment of aluminum killed steel the inclusions which form initially are typically alumina. As the dissolved oxygen content of the steel is reduced to very low levels magnesium may be reduced from the slag and subsequently react with the inclusions resulting in a shift towards higher contents of MgO and formation of magnesium aluminate spinel.
