Abstract

The invention provides a method for producing boric anhydride by adopting a cored medium-frequency induction furnace. The method comprises the following steps that: when the cored medium-frequency induction furnace is used for producing boric anhydride, an iron core or a metal cylinder core arranged in the cored medium-frequency induction furnace is heated to become a heat source for melting boricacid; the cored medium-frequency induction furnace is filled with boric acid, and when the temperature in the cored medium-frequency induction furnace reaches 400 DEG C, a discharging opening plugging object is opened; when the temperature in the cored medium-frequency induction furnace reaches 450-1000 DEG C, boric acid is decomposed with heat so as to form molten boric anhydride and water vapor, the flowing boric anhydride is allowed to flow out of a discharging opening, filling of the boric acid is conducted as a material surface descends, and the height, set for production, of the material surface in the cored medium-frequency induction furnace is maintained; and manual or mechanical drilling and deflation are needed in time. The cored medium-frequency induction furnace is adopted forproducing the boric anhydride, chemical products are produced through metallurgical technical equipment, production process or equipment is simple, production efficiency is high, product purity is high, energy utilization rate is greatly increased, and the method is applied to the technical field of the chemical industry.

Description

technical field [0001] The invention relates to a method for producing boric anhydride using a cored intermediate frequency induction furnace in the technical field of the metallurgical industry. Background technique [0002] At present, the cored intermediate frequency induction furnace is a power supply device that converts power frequency 50HZ AC power into intermediate frequency (above 300HZ to 1000HZ). The electric current supplies the medium-frequency alternating current flowing through the capacitor and the induction coil, generates high-density magnetic force lines in the induction coil, and cuts the metal material contained in the induction coil, generates a large eddy current in the metal material, and transfers the electric energy converted into heat energy. The cored intermediate frequency induction furnace is widely used in non-ferrous metal smelting, forging heating, heat treatment and tempering, etc. The smelting speed is fast, the power saving effect is goo...
