A skeleton structure for the induction coil of the embedded molten steel level sensor

Abstract

The invention discloses a framework structure for an induction coil in an embedded molten steel liquid level sensor. The framework structure comprises a barrel encircling wire carrier frame and a convex fastening plug mounted at one end of the barrel encircling wire carrier frame; the barrel encircling wire carrier frame and the convex fastening plug are both arranged in an outer protection body of the sensor; the barrel encircling wire carrier frame comprises a core middle column used for winding a primary coil subjected to eddy current regression, a first tile-shaped body used for winding asecondary coil with a judging and deviation compensation capability, and a second tile-shaped body used for winding an ultimate coil for emitting an electromagnetic signal; the first tile-shaped bodyand the second tile-shaped body are coaxial and connected in an up-down manner, and form a barrel-shaped structure; and the core middle column is arranged in the barrel-shaped structure. The frameworkstructure has the beneficial effects that non-filtered data acquisition and analysis are carried out on the signal of the induction coil inside the embedded molten steel liquid level sensor, and structure design is carried out on the framework of the induction coil of a core measurement part, so that the high-temperature resistance and the anti-interference performance of an electromagnetic coilassembly of the sensor and the matching property of original preamplifier and signal processor are ensured.

Description

technical field [0001] The invention relates to the technical field of molten steel level detection, in particular to a skeleton structure for an embedded molten steel level sensor induction coil. Background technique [0002] In modern continuous casting production, 80% of domestic and foreign continuous casting machine platforms use embedded (electromagnetic) molten steel level sensors, and the market share is very high. As one of the key equipment of the continuous casting machine, the embedded (electromagnetic type) molten steel level sensor is a non-destructive and non-contact liquid level sensor based on electromagnetic induction. Continuous casting production in steel mills. The magnetic induction coil is the core component of the liquid level sensor. The specification parameters, structure and materials of its skeleton directly affect the quality of the magnetic induction coil, the control accuracy of the electromagnetic induction, and the effective signal and signa...
