    摘要: A cupola for the melting of metal is provided with an auxiliary gas generator which supplies through the forehearth hot carbon monoxide rich gas to the bottom of the cupola as a source of heat. The heat of the gases maintains the cupola hearth and forehearth hot. Ordinary coal, or coke breeze or any other carbonaceous fuel may be burned in the generator. Additionally, the cupola may be allowed to go to zero output without cooling off.

    摘要: Apparatus for accurately pouring measured amounts of molten metal using an electromagnetic elevator. The trough of the elevator obliquely ascends from a pool of molten metal to a pouring spout and controls are provided to maintain the pool level at approximately a constant level so that by accurately repeating the time of the electrical energization of the elevator, the same amount of metal may be poured each time.

    摘要: A ladle adapted for treatment of molten iron with a reactant comprises a main chamber having sealed top and bottom ends. A teapot spout communicates with the bottom end of the ladle, and a dividing wall extends upwardly inside the main chamber from the bottom end of the ladle and forms a compartment within the main chamber. The compartment is adapted to contain the reactant. An opening in the top end of the main chamber allows placement of the reactant in the ladle compartment, and an airtight cover is mounted on the top end of the main chamber to cover the opening.

    摘要: A suspension frame for supporting a nose-tilt molten metal ladle includes end-to-end vertically arranged hydraulic cylinders above the ladle and totally protected within an elongated hollow enclosure. One of these cylinders is connected to an overhead carriage and operates to raise the suspension frame and the ladle as a unit. The other cylinder is connected to the ladle such that it raises the ladle relative to the suspension frame, causing the ladle to tilt about a pivotal connection at the ladle spout. The pouring device is completely self-contained with the hydraulic fluid reservoir, the hydraulic pump and motor, and a rechargeable electric storage battery for powering the pump motor all being supported on the suspension frame. Adjustment is provided to permit selection of the basic vertical position of the ladle within the suspension frame.

    摘要: A pilot flame to be positioned close to the charge opening of a cupola which uses carbon monoxide as a fuel in the presence of a fresh supply of combustion air, such carbon monoxide being drawn off from a position on the cupola where the temperature is above the self-ignition temperature of the carbon monoxide. Air preheated to a temperature above the self-ignition temperature of carbon monoxide may also be supplied.
