Manufacturing process of intermediate frequency furnace liner

Abstract

The invention relates to a manufacturing process of an intermediate frequency furnace liner, and belongs to the technical field of a sintering process of an electric furnace liner. The manufacturing process of the intermediate frequency furnace liner sequentially comprises the steps of forming a furnace liner core by pouring red copper water, placing the furnace liner core, manufacturing a furnaceliner blank body, knotting a furnace burden, adding a copper material into the furnace liner core for sintering for the first time and the second time, guiding out and collecting copper water formedby the molten copper material and the furnace liner core, and knotting a furnace mouth. The manufacturing process of the intermediate frequency furnace liner provided by the invention has the beneficial effects that the copper material in the furnace liner core are molten together with the furnace liner core so as to be guided out, collected and reused, the damage on the furnace liner caused by the secondary take-out of the furnace liner core is avoided, the production efficiency is improved, the production cost is reduced, an effect on protecting an intermediate frequency furnace body is achieved, a copper material smelting effect is ensured, a furnace liner filler is ensured to be tamped sufficiently, and the service life of the furnace liner is prolonged.

Description

technical field [0001] The invention relates to the technical field of sintering process of electric furnace lining, in particular to a manufacturing process of intermediate frequency furnace lining. Background technique [0002] The intermediate frequency electric furnace uses the intermediate frequency power supply to establish the intermediate frequency magnetic field, so that the induced eddy current is generated inside the ferromagnetic material and heats up, so as to achieve the purpose of heating the material. The intermediate frequency furnace is mainly composed of a power supply, an induction coil and a sintered furnace lining made of refractory materials in the induction coil. The furnace lining is filled with metal charge. When the induction coil is connected to the AC power supply, an alternating magnetic field is generated in the induction coil, and an induced electromotive force is generated in the charge. Since the charge itself forms a closed loop, an induced...
