Description
Technical Field
[0001] The utility model belongs to the technical field of ferroboron production, in particular to an electric heating furnace for ferroboron production. Background Art
[0002] Ferroboron is an alloy consisting of boron and iron. Ferroboron alloys are often used to make magnetic materials, such as permanent magnets, because of their good magnetic properties and wear resistance. The smelting process of ferroboron alloys usually involves mixing boron and iron in a certain proportion and then melting them at high temperature. Subsequently, through appropriate cooling and treatment processes, the desired ferroboron alloy products can be obtained.
[0003] Ferroboron smelting requires mixing raw materials such as boric anhydride, boron concentrate, steel scraps, and charcoal, and then slowly adding them into an electric furnace for smelting. Electric furnaces mainly work by converting electrical energy into thermal energy. The furnace is equipped with electric heating elements. When current passes through these electric heating elements, a large amount of heat is generated, thereby heating the ferroboron raw materials in the furnace. The furnace body of the electric furnace is usually made of refractory materials to withstand high temperatures and maintain the sealing of the furnace. The interior of the furnace is designed with reasonable heating areas and material flow channels to ensure that the raw materials are heated evenly and to facilitate operation and removal of products.
