(54) ИНДУКЦИОН ПЛАВКИ Т 1 Изобретение относитс  к области металлургии . Известна индукционна  печь дл  непрерывной плавки тугоплавких и высокореактивных металлов, содержаща  водоохлаждаемый тигель из металла с высокой электропроводностью и индуктор, расположенный концентрично тнглю(1. Однако известный тнгель имеет большие электрические потери в св зи с высокой электро- и теплопроводностью металла тигл , что снижает электрический КПД печн. Цель изобретени  - повысить КПД печн. Достнсаетс  это за счет того, что верхн   часть тигл  по высоте, равной 80 - от высоты индуктора, выполнена из полупроводникового материала. На чертеже изображена предлагаема  печь, общий вид. Печь состоит из тигл , верхн   часть 1 которого выполнена из полупроводникового материала, нижн   часть 2 из металла с высокой электропроводностью, и индуктора . 3. Работа осуществл етс  следующим образом . ПЕЧЬ ДЛЯ НЕПРЕРЫВНОЙ ЛАВКИХ И ВЫСОКОРЕАКТИВНЫХ ТАЛЛОВ 2 Металл плавитс  в верхней части t тигл , в которую ввод т электромагнитную энергию от индуктора 3. В этой зоне проводитс  процесс плавлени . При выт гивании слит КЗ 4 вниз зона кристаллизации определ етс  нижней частью 2 тигл , в которой расплав контактирует с холодной стенкой тигл  и затвердевает. Формула изобретени  Индукционна  пе дл  непрерывной плавки тугоплавких и высокореактивных металлов , включающа  водоохлаждаемый тигель из металла с высокой электропроводностью , индуктор, концентричный тиглю.отлинающа с  тем, что, с целью повышеии  КПД печн, верхн   часть тигл  по высоте, равной 80-90% от высоты индуктора, выполнена нз полупроводникового материала.

A known induction furnace for continuous smelting of refractory and highly reactive metals, containing a water-cooled crucible made of metal with high electrical conductivity and an inductor located concentrically tnglyu (1. However, the known thgel has large electrical losses due to the high electrical and thermal conductivity of the crucible metal, which reduces the electric Efficiency of furnaces The purpose of the invention is to increase the efficiency of furnaces. This is due to the fact that the upper part of the crucibles, at a height of 80, from the height of the inductor, is made of semiconductor material. The drawing shows the proposed furnace, general view. The furnace consists of crucibles, the upper part 1 of which is made of semiconductor material, the lower part 2 of metal with high electrical conductivity, and inductor. 3. The work is carried out as follows. OVEN FOR CONTINUOUS AIR HIGHLY REACTIVE TALLS 2 The metal melts in the upper part of the crucible, into which electromagnetic energy is introduced from the inductor 3. In this zone, the melting process is carried out. When drawing down the CZ 4 slit down, the crystallization zone is determined by the bottom part 2 of the crucible, in which the melt contacts the cold wall of the crucible and solidifies. Induction ne for continuous smelting of refractory and highly reactive metals, including a water-cooled crucible made of metal with high electrical conductivity, an inductor, concentric crucible. In order to increase the efficiency of the furnace, the upper part of the crucible has a height of 80-90% of the height of the inductor, made nz semiconductor material.
