Description

Intermediate frequency horizontal continuous casting furnace

Technical field

The utility model belongs to metallurgical technology field, relates to a kind of apparatus for melting metal, especially a kind of intermediate frequency horizontal continuous casting furnace.

Background technology

Induction melting furnace is one of the most effective technological equipment of modern casting industry melting, insulation.At present, induction melting furnace is mainly divided into mains frequency coreless induction melting furnace (referred to as main frequency furnace) and intermediate frequency induction melting furnace (referred to as intermediate frequency furnace).

Intermediate frequency furnace is a kind of metal smelting device of fast and stable, it is to change three-phase main-frequency alternating current into single-phase mid-frequency alternating current by converter plant, and in induction coil, produce the highdensity magnetic line of force, and make to produce very large eddy current in metal material, reach the object of heating, molten material; Have that speed of melting is fast, power savings good, scaling loss is few, energy consumption is low, metal ingredient evenly and the features such as labour intensity that reduced workman, is mainly used in the melting of the non-ferrous metals such as copper, aluminium.Existing intermediate frequency furnace is generally comprised of intermediate frequency power supply, capacitor box, body of heater (by furnace shell, induction coil, furnace lining, turndown reduction box), mechanical dumping furnace device (or hydraulic pressure turndown device), crucible etc.When melting, rise and melt soon, do not needed melt, electromagnetic agitation is effective, can allow all liquation to be gone out only, easily changes and is melted metal species, but be subject to the impact of furnace construction, can only cast by toppling over mode, and the daily output is not high, belongs to batch (-type) melting; And topple over mode and cast due to employing, product specification and length are restricted.

Main frequency furnace is mainly used in ferrous and nonferrous metals melting and insulation, and its capacity is large, can realize serialization and produce; But when smelting, every stove melt can not go out only, need to retain 30%～50% melt in stove, bad adaptability, can only be applicable to the continuous smelting of the single trade mark, when needs are changed trade mark production, need to expend large content of starting materials and time and carry out prepurging, cause unnecessary waste.And main frequency furnace frequently plays stove and pass stove will make furnace life greatly shorten, it is unfavorable for actual production, to arrange.

Summary of the invention

Technical problem to be solved in the utility model is that a kind of intermediate frequency horizontal continuous casting furnace simple and reasonable, that produce applicable to serialization is provided for the above-mentioned state of the art.

The utility model solves the problems of the technologies described above adopted technical scheme: a kind of intermediate frequency horizontal continuous casting furnace, comprise the body of heater with fixed mount, and in body of heater, be provided with crucible, on the skin of crucible, be wound with induction coil, characterized by further comprising:

One graphite base, is located at the bottom of crucible, and the left end of this graphite base is placed in crucible, and right-hand member is connected with crystallizer, and in graphite base, is provided with the endoporus that Gong the melt that is connected with crystallizer passes through;

One for controlling or regulate the stopper of melt flow, is plugged in crucible, and the lower end of stopper and the endoporus of graphite base plug.

As improvement, described endoporus is that level is opened in graphite base and through the right-hand member of graphite base, and the left end of endoporus upwards runs through and forms the Plug Division of pegging graft for stopper.

As improvement, described crystallizer is arranged on the sidewall of body of heater, and the inner end of crystallizer is connected with the right-hand member of graphite base, in the arranged outside of crystallizer, has cooling system.。

Improve, the junction of described graphite base and crucible is is convenient to the cone angle of 5～10 ° that melt flows out again.

Improve, described induction coil is to adopt copper pipe as winding wire again, at induction coil, around the home time, reserves the position of placing for graphite base in the bottom of crucible.

Compared with prior art, the utility model has the advantage of: in intermediate frequency furnace, increased graphite base, crystallizer, stopper, melt is realized horizontal casting by crystallizer, change original melt and toppled over the mode of casting, simple and reasonable, integrate intermediate frequency furnace and horizontal continuous casting furnace advantage, can realize serialization and produce.
