Abstract

The invention discloses a front box liquid level control system and a using method thereof. The control system comprises a manual operation box, an on-site operation box, an industrial personal computer, a PLC (programmable logic controller), a secondary instrument, an eddy current sensor at a front box, a driver, a servo motor and a stopper actuator. According to the invention, the eddy current sensor at a front box is arranged and is used for detecting a liquid level height of molten aluminum in the front box; the eddy current sensor generates an electromagnetic signal to generate eddy currents on the surface of molten aluminum; an induction signal is generated at an eddy current sensor coil at the front box by the eddy current and the signal intensity changes with a distance between thesurface of the molten aluminum to the bottom of the eddy current sensor at the front box, so that the liquid level of the molten aluminum can be accurately measured and the test precision can reach + / -0.3 mm.

Description

technical field

[0001] The invention relates to the technical field of front tank liquid level control, in particular to a front tank liquid level control system and an application method thereof. Background technique

[0002] Casting and rolling refers to the process of rolling deformation of molten metal while continuous casting and solidification. The liquid metal is directly poured into the roll gap, and the roll not only acts as a crystallizer but also rolls and deforms the metal at the same time. This process is also called liquid rolling or ingotless rolling.

[0003] During casting and rolling, it is necessary to use the front liquid tank to add aluminum liquid to the casting and rolling machine, but the aluminum liquid is a high-temperature liquid, and the liquid level is inconvenient to measure, and the measured value of the existing measurement technology is not accurate, which is prone to misjudgment.
