  • Charging stock for steel production
    Patent number: 5738704
    Abstract: An improved charging stock for steel production which facilitates earlier and more uniform carbon oxidation, and increases the rate of oxygen transport in the melt, comprises and iron-carbon alloy having silicon therein and an oxide-containing material. The iron-carbon alloy preferably has a ratio of carbon to silicon in the range of approximately 4-40:1. The ratio of oxide-containing material surface area to the weight of the iron-carbon alloy is preferably maintained in the range of 5-100 m.sup.2 /ton.

  • Composite charge for metallurgical processing
    Patent number: 5725631
    Abstract: A composite charge for metallurgical processing which reduces the content of non-metallic inclusions in the end product(s) comprises 40-83 wt. % of a metallic agent, 17-50 wt. % of an oxide agent and 0.1-10.0 wt. % of a carbonaceous agent. The carbonaceous agent includes a mixture of metal carbides and free carbon, preferably graphite, having a ratio in the range of 0.1-10.0:1.
