Abstract

------18/06/2018------(OCR) Page 1 of 1 Page Summary of Invention Sensing devices for measuring the surface level of liquid metals include lower and upper excitation windings and air intake windings. The excitation winding is perpendicular to the top face of the casting rod and is powered by the magnetic field. The magnetic wave lines propagate along the upper nominal away from the cast ingots and along the lower field lines covering the top and molten metal surfaces. The lower air coil is parallel to the excitation coil. where the induced voltage is generated by the field line below. The lower pitch is modified by varying the level of the metal surface. The top air coil is parallel to the excitation coil. vertically attached to the air coil below It has the same shape and characteristics as the air coil below. The upper field line creates an induced voltage and is free of significant interference generated by the metal surface. ------------ This invention involves the sensing device (1). For measuring the surface level of metal status Fluids in continuous foundry, including casting rods with a top face. where the opening (4) is filed lead to that where liquid metal is fed to it that has a unique feature that the detection equipment includes The excitation winding (7) is perpendicular to the top face of the molded rod and is positioned near the opening. that is powered by a current for generating a magnetic field. which its field line spreads along the field above, away from the formwork and along the field below which the stain covers the top surface of the model.
