FIELD : metallurgy, namely casting processes and equipment.
SUBSTANCE : method provides quick control of melt metal supply to casting machine by pumping it, braking and throttle controlling. Faraday-Ampere electromagnetic principle is used for electric current in single-sign magnetic field. Permanent magnets containing neodymium or similar rare earth high-energy materials provide unique magnetic range. Such neo-magnets usually in the form of cubicles are assembled to high-power configurations for creating intensified single-sign magnetic field in non-magnetic intervals significantly exceeding intervals that may be realized by other methods. Metal conduit is arranged in such magnetic interval for pumping and moving melt metal. In order to produce large number of similar castings, controlled interrupted metal flow is supplied at predetermined flow rate to row of similar separate casting molds. Invention allows eliminate usage of controlled metallurgical shutters or high-cost rotary mechanisms for metallurgical furnaces. Known furnaces whose height is too small for providing gravity supply of metal may be made more effective due to using variants of invention.
EFFECT : enhanced efficiency of processes.
