Problems solved by technology

[0004] At present, the leak detection of the crucible furnace is mainly realized through the open circuit or closed circuit installed in the furnace. When the crucible breaks, the metal solution directly conducts or fuses the circuit, thereby triggering an alarm. In the high temperature state of the furnace, it is easy to oxidize, and the wire is easy to disconnect or be melted. In addition, in the high temperature state, static electricity will be generated, and static electricity will also cause the entire circuit to fail. Therefore, this method is prone to false alarms or failures.

Embodiment Construction

[0018] In order to illustrate the idea and purpose of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Aiming at the problems of false positives or failures in the detection of crucible furnace leakage or metal solution overflow by using open circuit or closed circuit circuit in the furnace during the use of existing electromagnetic metal melting furnaces, this embodiment provides an improved method, which uses non- The contact sensor replaces the circuit installed in the furnace, and uses the change in the quality factor Q value of the load in the coil to determine whether the furnace is leaking. When the current passes through the coil, the change in the quality factor Q value will cause the current to change. When the current When a certain value is reached, an alarm signal is triggered, so as to realize timely and effective processing.

Abstract

The invention discloses a device and a method for checking damage and leakage of a smelting furnace in a non-contact induction manner. According to the invention, a non-contact inductor is adopted to correspondingly sense the change of current in a coil, and since an element is not in contact with a crucible, the element does not need to work in a high-temperature environment. Compared with the prior art, the device has the advantages of being long in service life, safe and reliable and low in cost, and cannot cause the problems of misinformation and failure.

Description

Technical field: [0001] The invention relates to an electromagnetic metal melting furnace, in particular to a non-contact induction detection device and method for leak detection of a melting furnace. Background technique: [0002] The current electromagnetic metal melting furnace mainly includes a crucible and a coil wound on the outer surface of the crucible. After the coil is energized, it sends out a high-frequency signal and generates electromagnetic induction with the crucible, so that the crucible heats up rapidly and reaches the set temperature to melt the metal in the crucible, thereby achieving For the purpose of rapidly melting metals. [0003] During the use of the electromagnetic metal melting furnace, if the crucible breaks or the loaded metal solution overflows, it will cause a fire, ranging from burning items to causing casualties. Therefore, it is necessary to monitor the crucible in real time when it is heated. When the crucible breaks or the metal solutio...
