摘要： An improved process for treating a body of molten metal is disclosed wherein a rotating impeller is used to disperse treatment media in the body. The process comprises the steps of providing a body of molten metal to be treated, the body having an upper region and a lower region, and providing an impeller on a shaft in said body. Treatment media is added to the body and the impeller is rotated to disperse the treatment media in the body. During the process of treating the body, the impeller is moved periodically between the lower portion and the upper portion of the molten metal body to reduce vorticity therein and to improve dispersion of the treatment media.

摘要： Disclosed is a pyrometallurgical reactor for entraining a low density particulate solid (e.g., coal) in a high density liquid (e.g., slag) in order to promote and accelerate reactions dependent upon contact between the solid and the liquid. The present disclosure develops interrelationship between the dimensions and rotation rate of a mechanical stirrer and the dimensions of the reactor vessel in order to achieve, simultaneously, good entrainment of the particulate solid which is delivered to the surface of the liquid, minimal entrainment of gasses along with the particulate solid, and minimal erosion of the vessel walls.

摘要： A method of adding a metallic additive to a molten metal having a temperature higher than the boiling point of the metallic additive comprises introduction of the metallic additive into the molten metal while the pressure within a double-walled ladle structure is adjusted to a value substantially equal to 70 to 85% of the vapor pressure evolved by the vaporization of the metallic additive. The method employs the double walled ladle structure having an adiabatic space formed between inner and outer containers which constitute the ladle structure together with a lid adapted to close the top opening of the ladle structure to enable the pressure within the ladle structure can be adjusted to the predetermined value.

摘要： A protective alloy addition apparatus is suitable for installation on a refractory lined rod positioned in a pouring ladle. The apparatus comprises a base member adapted for positioning on the rod and an outer sleeve and inner concentric sleeve positioned on the base member so as to form a first chamber between the sleeves and a second chamber radially inward of the inner sleeve. A protecting first addition agent is positioned in the first chamber and an alloy addition agent to be protected is positioned in the second chamber. The addition agent to be protected is also topped and bottomed with the protecting addition agent in the second chamber.
