Study of Oxidative Processes in a High-Temperature Two-Phase Carbon-Containing Gas Flow.

A laboratory study was made of the effect of the rate of introduction of pulverized coal additives on their reactivity in an oxidative gas flow, including the flow during the blowing of an iron-carbon melt. It was found that controlling the relative quantity of pulverized coal fuel in the blast air flow makes it possible to switch over easily from conditions of nonoxidative heating and carburization of materials and bath to conditions of oxidative action on the melt with partial replenishment of the carbon in the melt for more rapid completion of the melting and dissolution of the remaining scrap.
