Furnace lining detection device of induction furnace body

Abstract

The invention discloses a furnace lining detection device of an induction furnace body. The device comprises furnace body side sensors and further comprises a control system and a data instrument, wherein the furnace body side sensors are divided into at least two blocks installed in a furnace lining of the induction furnace body side, the sensors in at least one block are connected in series, the sensors in two blocks are are connected with the control system and the data instrument through wires, the control system and the data instrument are arranged outside the induction furnace body, and signals for feeding back impedance changes are transmitted to the control system and the data instrument. The control system comprises a data adjusting resistor VR1, a filtering circuit RC-L, a data comparison circuit K1-R1, an alarming executing circuit and a power-off protection circuit, and the data adjusting resistor VR1, the filtering circuit RC-L, the data comparison circuit K1-R1, the alarming executing circuit and the power-off protection circuit are sequentially connected. The detection device is capable of real-time detection and intelligent control, safe, reliable, low in cost, simple in structure, easy to operate and capable of preventing various potential hazards caused by the phenomenon that high-temperature molten steel penetrates through a furnace.

Description

technical field

[0001] The invention relates to an induction furnace lining detection device, which belongs to the field of electromechanical technology. Background technique

[0002] Induction furnace is a commonly used electromechanical equipment. The structure of the furnace itself roughly includes the furnace shell, coil, upper and lower refractory plates, furnace lining, etc.

[0003] During the working process of the induction furnace, the furnace lining is in direct contact with molten steel, slag and furnace gas during the steelmaking process, and is constantly subjected to physical, mechanical and chemical erosion, so the quality of the furnace lining is extremely important. Furnace lining is generally made of refractory materials directly rammed in the furnace body. The quality of the ramming mainly depends on the uniformity and compactness of the ramming. These two factors mainly depend on the person. Of course, different people will have different effects. On t...
