초록 ▼

An improved molten metal spray forming atomization ring converter adapted for the spray forming of a refined molten metal from a molten metal refining or melting chamber wherein the molten metal is atomized into tiny molten droplets by gas impingement in a stream of molten metal and to the structure by which the molten metal droplets are preferentially directed to and deposited on a target surface. The molten metal spray forming atomization ring converter is adapted to control the flow of liquid metal droplets and to avoid a backflow of such droplets during the gas atomization by providing structure, such as small apertures to the inner diameter of the ring, by providing large holes through the inner diameter and adding a porous metal filter to cover the large holes or by providing a gas supply system independent from the atomization system gas supply, such that a pressure or diffused source of gas is provided at the inner bore. These modifications produce a relatively small mass flow of gas sufficient to feed the entrainment requirement of the high speed jets, but sufficiently low enough to avoid preatomization of the liquid metal wherein backsplash of the metal is reduced and/or prevented.

대표청구항 ▼

A spray forming converter for atomizing a molten metal comprising: a manifold for receiving a gas therein and for passing a stream of molten metal therethrough; at least one primary gas directing structure, including at least three jets about the periphery of the manifold, operatively positioned in the manifold, for directing the gas through the at least one primary gas directing structure such that the gas engages the molten metal stream after passing through the manifold for converting the metal stream into a spray pattern of molten metal droplets; and at least one secondary gas directing structure, operatively positioned in the manifold, for providing a gas pressure magnitude sufficient to prevent backsplash but not of sufficient magnitude that the gas from the secondary gas directing structure interferes with the flow of the stream of molten metal as the stream passes inside the manifold.
