Novel capacity-enlarging induction furnace body and process

Abstract

The invention discloses a novel capacity-enlarging induction furnace body and a process. The novel capacity-enlarging induction furnace body comprises a crucible, a crucible furnace wall and an induction coil, and is characterized in that: the crucible is a cylindrical straight crucible, and has equal upper and lower diameters; the thickness of the crucible furnace wall on the front of the induction furnace is unequal to that of the crucible furnace wall on the rear of the induction furnace, and the front half crucible furnace wall near a furnace mouth is thinner than the rear half crucible furnace wall; and the bottom surface of the crucible and the lower edge of the first turn of induction coil on the lower part of the induction coil are aligned with each other and positioned on the same horizontal plane. The novel capacity-enlarging induction furnace body has the advantages of improving the electrothermal efficiency and smelting capacity of the induction furnace and reducing furnace rupture accidents, and can be widely applied to various medium frequency and main frequency furnaces.

Description

technical field [0001] The invention relates to a furnace body and a process, in particular to a novel capacity-increasing induction furnace body and a process for an induction electric furnace, belonging to the technical field of metal material smelting and processing. Background technique [0002] Induction furnaces are widely used in my country's metallurgical industry, mainly in the smelting and research experiments of high value-added special alloy steels and non-ferrous metal alloys. The induction furnace body mainly includes three parts: the induction coil, the crucible, and the built crucible furnace wall. At present, the bottom of the crucible of the induction furnace is generally placed above the second-turn induction coil at the bottom of the induction coil to ensure the temperature of the furnace bottom; However, according to the measurement and the principle of electromagnetic field, the magnetic induction intensity at the first and second turns of the inductio...

AI Technical Summary

Problems solved by technology

However, according to the measurement and the principle of electromagnetic field, the magnetic induction intensity at the first and second turns of the induction coil at the bottom of the induction coil is still relatively strong; as the age of the furnace increases, there is a risk that the upper mouth of the inclined crucible will be eroded by the slag and easily penetrate the furnace. The problem that the volume of slag deposition in the lower part is gradually reduced

So a slanted crucible is not safe

The induction furnace body of this design does not make full use of the magnetic field energy, resulting in waste of electromagnetic energy, low electrothermal efficiency, and small furnace capacity
