Abstract
The utility model belongs to the technical field of an intermediate-frequency electric furnace, which particularly relates to an intermediate-frequency electric furnace for smelting metals. The intermediate-frequency electric furnace for smelting metals of the utility model is composed of a crucible, a furnace body, an induction coil and a pedestal, wherein, after the pedestal of the furnace and a fire-proof plate on the periphery of the lower part of the crucible are mixed by fire-proof cement and high alumina sands, iron wires are used for fire-proof materials which are made of frameworks in the middle and the upper part of the crucible is provided with a circulating cooling water pipe. Therefore, the utility model has the advantages of low cost, convenient maintenance, uniform cooling and no transverse cracks on the top.
Description
(1) technical field
The utility model belongs to the technical field of middle frequency furnace, particularly a kind of Metal Melting middle frequency furnace.
(2) background technology
Usually, the refractory material of middle frequency furnace furnace bottom adopts asbestos board, and refractory brick is adopted on crucible top.There are two big defectives in this structure: 1, the expense height, be difficult for maintenance operation.2, the crucible inhomogeneous cooling is even, and the top is easy to generate transversal crack.
(3) summary of the invention
The purpose of this utility model be to provide a kind of expense low, for ease of maintenaince, cooling even metal melting middle frequency furnace.
The purpose of this utility model is achieved in that
Metal Melting middle frequency furnace of the present utility model is made up of crucible, body of heater, induction coil, base, after the peripheral refractory slab in furnace base and crucible bottom adopts refractory cement and high alumina sand to mix, and the middle refractory material of making as skeleton with iron wire; The top of crucible is circulating cooling water pipe.
Metal Melting middle frequency furnace of the present utility model, crucible top circulating cooling water pipe adopts waste and old induction coil.
After furnace base and crucible bottom peripheral employing refractory cement and high alumina sand mixed, the middle refractory slab of making as skeleton with iron wire replaced asbestos board, and expense is low, and is easy to maintenance.Circulating cooling water pipe is adopted on crucible top, replaces existing special-shaped special-purpose fire-resistant brick, and crucible is evenly cooled off, and prevents that crucible from producing transversal crack, is convenient to maintenance operation.
Therefore, the utlity model has that expense is low, easy to maintenance, cooling evenly, the top do not produce transversal crack.
(4) description of drawings
Accompanying drawing is a cross-sectional view of the present utility model
Among the figure, 1. cooling water pipe, 2. asbestos board, 3. crucible, 4. body of heater, 5 induction coils, 6. refractory slab, 7. base
(5) specific embodiment
Be further described below in conjunction with accompanying drawing:
Crucible 3 places in the body of heater 4, and the bottom of crucible 3 is that base 7 is isolated with body of heater, and periphery, bottom be refractory slab 6, base 7 and refractory slab 6 adopt prices low, buy refractory cement and high alumina sand mixing easily, the refractory material that the centre makes as skeleton with iron wire.The periphery, middle part of crucible is an induction coil 5, and induction coil 5 is used for heating.The circulating cooling water pipe 1 that the top of crucible adopts waste and old induction coil to make replaces existing special-shaped special-purpose fire-resistant brick, like this, crucible is evenly cooled off, and prevents that crucible from producing transversal crack, is convenient to maintenance operation.
Claims (2)
1. Metal Melting middle frequency furnace, form by crucible (3), body of heater (4), induction coil (5), base (7), it is characterized in that: after the peripheral refractory slab in furnace base (7) and crucible bottom (6) adopts refractory cement and high alumina sand to mix, the middle refractory material of making as skeleton with iron wire; The top of crucible is circulating cooling water pipe (1).
2. Metal Melting middle frequency furnace according to claim 1 is characterized in that: circulating cooling water pipe (1) is waste and old induction coil.
