Abstract
The invention provides a medium-frequency induction furnace. The medium-frequency induction furnace comprises a furnace cover, a metal pipe, a refractory material and a crucible, wherein the crucible is positioned in the furnace cover; the diameter of an upper opening of the crucible is greater than the diameter of the bottom of the crucible; the metal pipe surrounds the outer layer of the crucible; a circulating water passage is arranged in the metal pipe; the refractory material is arranged between the crucible and the metal pipe and is laid between the crucible and the bottom of the furnace cover; a gap is reserved between the metal pipe and the side wall of the furnace cover. The metal pipe is a copper pipe. The furnace cover is provided with an observation window. The medium-frequency induction furnace also comprises a furnace cover, wherein the upper part of the furnace cover is provided with a through hole which is concentric with the crucible. The crucible is made of fused magnesite or a refined quartz sand material. The metal pipe is connected with control equipment through a cable. The medium-frequency induction furnace has the advantages and positive effects that an induction coil of the medium-frequency induction furnace with an optimal structure in the technical scheme is made of copper and the circulating water passage is arranged in the furnace, so that circulating water can be used for cooling in an electrification process to prevent over-heating melting of the electromagnetic induction coil.
Description
Technical field
The present invention relates to the melting field, particularly a kind of intermediate frequency furnace
Background technology
In the melting field, major part is carried out melting with coke, coal combustion heat production, the method power consumption is large and seriously polluted, there is fraction to adopt the resistance heating principle to carry out melting, but the equipment imperfection causes the resistance induction coil easily to damage in long-term heating power process, and crucible makes and cylindrically be difficult for to take out, cause operating difficulties after melting.
Summary of the invention
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of intermediate frequency furnace, comprise stove outer cover (4), metal tube (1), refractory material (2), crucible (3), described crucible is positioned at bonnet inside, described crucible upper opening diameter is greater than base diameter, described crucible outer surface spiral is around metal tube is arranged, described metal tube inside has cyclic water channel, there is refractory material between described crucible and metal tube, be covered with refractory material between described crucible and stove outer cover bottom, between described metal tube and stove outer cover sidewall, space arranged.
Further described metal tube is hollow copper pipe.
The further described asbestos cloth (6) that also comprises, described asbestos cloth is between metal tube and crucible
Further described stove outer cover has watch window.
Further also comprise a bell (5), bell is positioned at the bonnet top, bell top have one with the through hole of crucible concentric.
Further described crucible is fused magnesite or is the purity quartzite material.
Further described metal tube is connected with control appliance by cable.
Advantage and good effect that the present invention has are: adopt above technical scheme that a kind of intermediate frequency electromagnetic induction furnace of structure optimization is provided, at its induction coil, adopt copper to make, and wherein there is the circulation water channel, in its galvanization, can utilize circulating water to be lowered the temperature, prevent the electromagnetic induction coil over hot melting, crucible is designed to up big and down small structure, easily takes out.

The specific embodiment
As shown in Figure 1, 2: a kind of intermediate frequency furnace, comprise stove outer cover 4, metal tube 1, refractory material 2, crucible 3, described crucible is positioned at bonnet inside, described crucible 3 upper opening diameters are greater than base diameter, described crucible 3 outer surface spirals are around there being metal tube 1, and described metal tube inside has cyclic water channel, has refractory material 2 between described crucible and metal tube, be covered with refractory material between described crucible and stove outer cover bottom, between described metal tube and stove outer cover 4 sidewalls, space arranged.The temperature that cyclic water channel can reduce metal tube to water flowing prevents the excess molten of being heated.
Further described metal tube is hollow copper pipe.Hollow tube can lead to circulating water, and copper pipe is lowered the temperature.
The further described asbestos cloth 6 that also comprises, described asbestos cloth is between metal tube and crucible.Facilitate the laying of refractory material to make firm by ramming.
Further described stove outer cover has watch window.Can observe at any time the situation of metal tube, the thermolysis of also holding concurrently.
Further comprise a bell 5, bell is positioned at stove outer cover top, bell top have one with the through hole of crucible concentric.The metal that prevents the inside is splashed, and can understand the melting process by through hole.
Further described crucible is fused magnesite or is the purity quartzite material.Two material fusing points are high, meet the requirement of the various carbon steels of melting, steel alloy.
Further described metal tube is connected with control appliance by cable.
Concrete link and working method:
Medium-frequency induction furnace, first, at the two-layer asbestos cloth of copper tube coil the inside paving, laid refractory material to facilitate.Then the refractory material of the various granularities that mix is spread to the 250mm left and right toward bottom, solid with the instrument ramming, put the crucible flue after striking off, flue tube structure is up big and down small, such structure is convenient to extract the crucible flue.Fixing solid after, then put into refractory material between the asbestos cloth in crucible flue and copper tube coil, ramming is solid, can carry out melting, puts into and treats smelting metal, the water flowing of then being switched on, added hot smelting by electromagnetic induction.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the present patent application scope and improvement etc., within all should still belonging to patent covering scope of the present invention.
