Description

Technical Field

[0001] The utility model relates to the technical field of medium frequency furnaces, in particular to a lining cover plate structure of a medium frequency furnace in spheroidizing agent production. Background Art

[0002] A medium frequency furnace is a power supply device that converts 50HZ industrial frequency alternating current into medium frequency (300HZ to 1000HZ). It rectifies three-phase industrial frequency alternating current into direct current, and then converts direct current into adjustable medium frequency current to supply the medium frequency alternating current flowing through the capacitor and induction coil, generating high-density magnetic lines in the induction coil, cutting the metal material contained in the induction coil, and generating large eddy currents in the metal material.

[0003] When heating and melting some materials, it is necessary to surge the medium frequency furnace, such as the processing of spheroidizers. The lining cover of the medium frequency furnace is in contact with the lining, and the lining will expand during long-term high-temperature use, causing the cover to warp. In addition, there is a high-temperature liquid in the furnace for a long time. During some operations, the high-temperature liquid will splash to the inner edge of the cover, causing the inner edge of the cover to be burned by the high-temperature liquid. Eventually, the cover can no longer be used and is scrapped. The new lining cover needs to be machined and the processing and production cost is high. Utility Model Content
