Description
Technical field
The present invention relates to a kind of channel, and in particular to a kind of horizontal casting duplex channel of not easily broken ditch.
Background technology
In current coloured industry, there is the application of core induction channel furnace more and more, be widely used in melting copper and copper closes
The smelting furnace and holding furnace of gold.It is characterized in heating fast, efficiency high, that iron loss is few, environment friendly and pollution-free, site environment is good etc. is excellent
Point.
Wherein it is individual it is most commonly used be exactly horizontal casting induction furnace, it is to utilize electromagnetic induction and heating effect of current principle,
The melting of the non-ferrous alloy of progress.Basic functional principle be using power frequency supply and by melt composition channel as secondary
Coil.During work, it is passed through in induction coil after alternating current, alternating magnetic field is produced in iron core.Induced current, which is concentrated, to be produced
In the melt of secondary coil, the electric current that channel is formed heats to channel itself, first melts channel, then melts body of heater
The cathode copper of interior addition.
But the disconnected ditch time occurs in use, when channel is broken, sensing channel fails to form closed loop, can not
Induced-current is produced, dead stove accident is finally directly contributed, body of heater will be made entirely to scrap after there is dead stove, so as to cause to be produced into
This increase.Find that channel can all occur in channel channel in new stove starts heating, normal productive process by studying
Fracture accident.
The content of the invention
Goal of the invention：It is double the invention provides a kind of horizontal casting of not easily broken ditch in order to solve the deficiencies in the prior art
Disjunctor channel, by the improvement to channel structure, it is reduced the risk of disconnected ditch, and can be kept after channel blowing out existing
Shape, it is used repeatedly so as to realize, increases body of heater service life.
The purpose of the present invention realizes that a kind of horizontal casting duplex of not easily broken ditch melts by such technical scheme
Ditch, the duplex channel is by top, bottom, and the fusing rib of middle interconnecting piece and both sides forms two channels, and two molten
The symmetrical formation Type B of ditch, the duplex channel top exterior walls are planar structure, and the top inner wall of two channels is V-shaped,
And horizontal tilt angle is 6 °, the bottom is that arc structure has inner ring and outer shroud, the fusing rib inwall and inner ring phase
Point of contact is located at circular arc level and offsets up 20 °, and the points of tangency of outer wall and outer shroud is located at circular arc level and offsets up 14 °, described
The points of tangency of middle interconnecting piece inwall and inner ring is located at circular arc level and offsets up 15 °.
Preferably, be arc transition between the top inner wall and fusing rib inwall, and arc radius is 40mm,
It is arc transition between top inner wall and middle interconnecting piece inwall, and arc radius is 50mm.
Preferably, the top exterior walls size is 914mm.
Preferably, the inner ring radius of the bottom is 227.5mm, outer shroud radius is 262.5mm.
The horizontal casting duplex channel of disclosed a kind of not easily broken ditch, in order to ensure that it can repeat to make
With, it is desirable to the channel that is formed and new channel shape keep preferable uniformity after copper water solidification during blowing out, therefore by top
Inwall designed using the V-type of level of approximation, be easy to copper water to form backflow, so as in blowing out, copper water in centre in stirring
Top is horizontality under gravity, it is ensured that the changes of section of annular channel is smaller, and grading resistance change also compared with
It is small, when smelting furnace is once again powered up keeping preferable synchronism in fusion process.
Find that the place of disconnected ditch easily occurs in channel blow-on first or using after above time half a year by long term test
Positioned at the channel upper left corner and the side in the upper right corner, for this problem, the region in practical structures thickening transition position has been subjected to
Reason, is adjusted for the points of tangency of bottom inner ring and outer rings, and the points of tangency of inner and outer ring is in same position, so that it is guaranteed that
The area thickness increased.
In addition in order to ensure the quality on made-up belt surface, both sides channel must be in symmetrical structure, and also inside unilateral channel
Relative symmetry, although top inner wall tilts 6 ° in this structure, the power deviation of both sides is in prescribed limit during actual stirring, not shadow
Ring normal quality requirement.
Compared with prior art, the horizontal casting duplex channel of disclosed a kind of not easily broken ditch, by right
Structure is improved so that channel keeps existing shape after blowing out, it is ensured that synchronism when being once again powered up, so as to realize repeatedly
Reuse, and then increase body of heater service life, and by carrying out structure improvement to both sides frangible zone, reduce the wind of disconnected ditch
Danger, and then reduce production cost.
Brief description of the drawings
Fig. 1 is the physical dimension schematic diagram of the present invention.
Embodiment
Below in conjunction with the accompanying drawing of the present invention, clear, complete description is carried out to the technical scheme of the embodiment of the present invention.
As shown in figure 1, a kind of horizontal casting duplex channel of disclosed not easily broken ditch, by two channels 1
