Abstract

FIELD: iron melting. SUBSTANCE: induction furnace includes inductor 1 and refractory crucible 2, having ducts 3 in its refractory wall. Ducts 3 are connected by their inlet portion with cavity of crucible and by their outlet portion with taphole 4. Ducts 3 of refractory wall of crucible are in the form of curved hollow grid or in the form of hollow rings, mutually joined by hollow struts, in the form of hollow sleeves or zigzag shaped hollow struts, in the form of arranged one after another hollow grids or they are in the form of refractory tubes. EFFECT: high efficiency of furnace, simplified design, low labor consumption at remounting for performing continuous charge melting process and superheating melt metal. 7 cl, 10 dwg

Использование: для плавки чугуна. Цель: упрощение конструкции, повышение экономичности, термического коэффициента полезного действия при непрерывности процесса плавки шихты и перегрева жидкого металла. Сущность изобретения: индукционная печь содержит индуктор 1 и огнеупорный туннель 2. В огнеупорной стенке тигля 2 выполнены каналы 3, которые соединены во входной части с полостью тигля, а в выходной части с выпускной леткой 4. Каналы в огнеупорной стенке тигля выполнены или в виде изогнутой пустотелой сетки, или в виде пустотелых колец, которые соединены пустотелыми стойками, или в виде пустотелых втулок, или в виде зигзагообразных пустотелых стоек, или в виде системы следующих друг за другом пустотелых сеток, или выполнены из огнеупорных трубок. Положительный эффект: индукционная печь имеет высокую производительность, простоту конструкции, низкую трудоемкость переоборудования для ведения непрерывного процесса плавки шихты и перегрева жидкого металла. 7 п. ф-лы, 10 ил.Use: for melting cast iron. Purpose: to simplify the design, increase efficiency, thermal efficiency with the continuity of the process of melting the mixture and overheating of liquid metal. The inventive furnace contains an inductor 1 and a refractory tunnel 2. In the refractory wall of the crucible 2 channels 3 are made, which are connected in the inlet part to the cavity of the crucible, and in the outlet part to the outlet notch 4. The channels in the refractory wall of the crucible are made or in the form of a bent hollow mesh, or in the form of hollow rings that are connected by hollow racks, or in the form of hollow sleeves, or in the form of zigzag hollow racks, or in the form of a system of successive hollow grids, or made of refractory pipes side. Positive effect: the induction furnace has high productivity, simplicity of design, low complexity of the conversion for conducting a continuous process of melting the charge and overheating of liquid metal. 7 p. Fs, 10 ill.
