Intermediate frequency furnace tilting control system and method and intermediate frequency furnace

Abstract

The invention provides an intermediate frequency furnace tilting control system and method and an intermediate frequency furnace. The system comprises a driving circuit and a limiting controller, wherein the driving circuit is used for driving a furnace body of the intermediate frequency furnace to be tilted or reset, and the limiting controller is used for disconnecting the driving circuit from apower supply when the furnace body is tilted to a preset position, so that the furnace body stops tilting or resetting. According to the system, the limit position of tilting of the intermediate frequency furnace can be effectively controlled, sudden stop of a tilting mechanism at any position can be realized, the phenomenon that the tilting action of the intermediate frequency furnace is causedto be out of control due to operation errors or equipment faults, so that accidents are caused is avoided, and the operation safety of the intermediate frequency furnace is improved.

Description

technical field [0001] The invention relates to the technical field of aluminum electrolysis anode assembly, in particular to a tilting control system and method for an intermediate frequency furnace and an intermediate frequency furnace. Background technique [0002] During the assembly process of aluminum electrolytic anodes, the intermediate frequency furnace tilting system is used to dump the molten iron in the intermediate frequency furnace into the pouring ladle on the pouring trolley. The current tilting system of intermediate frequency furnace mainly has the following problems: [0003] 1. There is no limit position limit for the tipping of the furnace body. If there is negligence in the process of dumping molten iron, the furnace body may exceed the limit position, resulting in splashing of molten iron, breaking of the water-cooling cable or crashing of the induction coil. Both are huge, and therefore, not very secure. [0004] 2. The tipping system cannot realize...

AI Technical Summary

Problems solved by technology

[0003] 1. There is no limit position limit for the tipping of the furnace body. If there is negligence in the process of dumping molten iron, the furnace body may exceed the limit position, resulting in splashing of molten iron, breaking of the water-cooling cable or crashing of the induction coil. Both are huge and therefore, not very safe

[0004] 2. The tipping system cannot realize emergency stop. If the contacts of the contactor are stuck or the button of the operating handle is stuck during the process of dumping molten iron, the tipping action will not stop, and the only measure to take is to cut off the power of the control cabinet. The process is cumbersome and will delay too much time, therefore, the security is not high
