Description
Technical field
The utility model belongs to copper and Alloy Processing field thereof, particularly relates to a kind of channel structure reducing disconnected ditch risk.
Background technology
Operating efficiency is high, working condition good, alloy melt stable components, be easy to the advantages such as automated job to have core line frequency furnace (under be called for short main frequency furnace) to have, and is the capital equipment of copper and alloy processing strand thereof.But existing have core line frequency furnace always by the channel ditch that breaks is perplexed, after new brickwork to open stove running first slightly improper, channel will be caused to scrap because of disconnected ditch, its main cause is that the gas that the pore of channel cast-internal and ramming mass are discharged when baker cannot be discharged outside channel smoothly, after the lower part that channel cross section is less melts prior to upper part, the melting zone that gas accumulation significantly changes in channel cross section, easily cause material spray and cause disconnected ditch, cannot be formed closed circuit to induced-current, and then cause main frequency furnace channel and ramming mass to scrap.
Utility model content
The problem that the utility model solves is to provide a kind of channel structure reducing disconnected ditch risk, baker and open the gas that stove produces for the first time and discharge outside channel by air discharge duct, prevents channel from causing material spray, the continuous ditch of guarantee main frequency furnace channel.
For solving the problem, the utility model embodiment provides a kind of channel structure reducing disconnected ditch risk, comprise: channel both side surface has first row air drain, or on the end face of described channel structure, have second row air drain, described first row air drain or second row air drain fill up combustible material and bond.
Optionally, the both side surface of described channel structure has first row air drain, and the end face of channel structure has second row air drain.
Optionally, described combustible material is timber.
Optionally, the depth bounds of described first row air drain, second row air drain is 3 ~ 5mm.
Optionally, the width range of described first row air drain, second row air drain is 6 ~ 10mm.
Optionally, described first row air drain is initial from channel top, extends on the arc surface of channel side.
Optionally, described second row air drain is initial from channel top, and the line extended between adjacent two induction coil installing hole centre points stops.
Compared with prior art, the technical program has the following advantages:
The described channel structure reducing disconnected ditch risk, at both side surface or the end face processing air discharge duct of channel.After processing air discharge duct, with timber air discharge duct filled up and bond.In sintering process, timber is carbonized or is burnt, the air discharge duct be originally filled is made to occur gap, make the gas that ramming mass produces in sintering process, discharge outside channel by air discharge duct, the gas that in Starting-up process, channel fusing is discharged, also can discharge outside channel by air discharge duct, prevent material spray and cause disconnected ditch, ensureing the continuous ditch of main frequency furnace channel.
Accompanying drawing explanation
Fig. 1 is the structural representation reducing the channel structure of disconnected ditch risk of the utility model embodiment;
Fig. 2 is the part section structural representation reducing the channel configuration vent groove of disconnected ditch risk of the utility model embodiment.
Detailed description of the invention
Fig. 1 is the structural representation reducing the channel structure of disconnected ditch risk of the utility model embodiment.Fig. 2 is the part section structural representation reducing the channel configuration vent groove of disconnected ditch risk of the utility model embodiment, and the other parts in fig. 2 beyond air discharge duct, prescind with the circular arc of bottom.
Below in conjunction with accompanying drawing, by specific embodiment, clear, complete description is carried out to the technical solution of the utility model.
Please refer to Fig. 1 and Fig. 2, is a kind of channel structure reducing disconnected ditch risk of the utility model embodiment.What adopt in the present embodiment is the channel of holes, the first row air drain 14 of straight shape is processed in the center of the both side surface 12 of channel, described first row air drain 14 size as shown in Figure 2, the span of groove depth A is 3 ~ 5mm, the span of width B is 6 ~ 10mm, in the present embodiment, the value of described groove depth A is 4mm, and the value of width B is 8mm.Described first row air drain 14 is processed from channel top 13 initial, extends on the arc surface of channel side 12.
In the present embodiment, the both ends of the surface 11 of channel are processed with the second row air drain 15 of straight shape, its size is consistent with the first row air drain 14 that both side surface is processed, be positioned at the position of the axis of symmetry between two induction coil installing holes 16, second row air drain 15 is processed from channel top 13 initial, and the line extended between adjacent two induction coil installing hole centre points stops.In other embodiments, when channel has three or more induction coil installing hole, between every two adjacent induction coil installing holes, the position of the axis of symmetry is provided with described second row air drain, when channel only has 1 induction coil installing hole, then without second row air drain.
In the present embodiment, described channel structure has the second row air drain 15 of the first row air drain 14 being positioned at channel side 12 and the both ends of the surface 11 being positioned at channel, in other embodiments, described channel structure also only can have the second row air drain of the first row air drain being positioned at channel side or the both ends of the surface being positioned at channel.
After processing described first row air drain and second row air drain, with timber or other combustible materials, first row air drain and second row air drain filled up and bond, making up the removed metal because of processing air discharge duct, make channel structural outer surface smooth.The kind of described timber, other combustible materials and glue is without particular/special requirement, and combustible material only needs burn, carbonize or gasify during baker, and glue then can good bond.
Due to channel structure melt time, first bottom is melted, then slowly up melt, in fusion process, be present in air wherein or impurity can flock together gradually, and form gases at high pressure, not only make the risk that there is disconnected ditch between molten metal liquid and unfused channel, once unfused channel somewhere and the external world are melt through, then high pressure gas knows from experience the metal charge ejection channel of sweeping along partial melting, make channel that disconnected ditch occur, disconnected ditch generally there will be the position of A, B, C in FIG.And in the present embodiment, in sintering process, timber is carbonized or is burnt, the air discharge duct be originally filled is made to occur gap, make the gas that ramming mass produces in sintering process, discharge outside channel by air discharge duct, in first Starting-up process, channel can melt, in fusion process, the pore existed during channel casting, loose in gas also can discharge outside channel by air discharge duct, prevent channel from causing material spray, and then ensure that disconnected ditch situation does not appear in main frequency furnace channel, thus ensure main frequency furnace steady operation.
Although the utility model with preferred embodiment openly as above; but it is not for limiting the utility model; any those skilled in the art are not departing from spirit and scope of the present utility model; the Method and Technology content of above-mentioned announcement can be utilized to make possible variation and amendment to technical solutions of the utility model; therefore; every content not departing from technical solutions of the utility model; the any simple modification done above embodiment according to technical spirit of the present utility model, equivalent variations and modification, all belong to the protection domain of technical solutions of the utility model.
