Abstract
The utility model provides a device for producing vanadium nitride alloy, which comprises a furnace casing, and is characterized in that a crucible is arranged in the furnace casing, and the circumferential walls and the bottom of the crucible are coated by heat-insulating furnace linings, the upper end portion of the crucible is provided with a heat-insulating furnace cover and a metal furnace cover in turn, the circumferential walls of the heat-insulating furnace lining are provided with a medium-frequency induction coil, and a nitrogen inlet pipe which leads to the crucible is arranged on the lower portion of the furnace casing. The utility model has the effects that CO gas in a furnace can be fully utilized, the quality of product is improved, the linings in the furnace are not easy to deform and be damaged, thereby guaranteeing the stable production, and finally the cost of constructing furnace is low, the maintenance cost is low and the maintenance period is short.
Description
Technical field:
The utility model relates to a kind of modifying device of making alloy in the metallurgy industry, particularly a kind of device of making alloy of vanadium nitride.
Background technology:
Existing device kind of making alloy of vanadium nitride is more, and pushed bat kiln is wherein a kind of.The body of heater of pushed bat kiln is horizontal, with the type of heating heating of resistance.The process that pushed bat kiln is made alloy of vanadium nitride is: pulverous vanadous oxide and graphite are added as briquetting behind the polyvinyl alcohol water solution three mixing of binding agent, moulding, add the material after the moulding in the pushed bat kiln continuously again, feed nitrogen or ammonia simultaneously, made in 2-6 hour in 1000-1800 ℃ of reaction and to contain V77-81%, the vanadium nitride of N1-8%.Pushed bat kiln existing deficiency in making alloy of vanadium nitride has: 1, the body of heater of pushed bat kiln is horizontal, and the CO gas in the stove fails to make full use of, because the CO gas that produces in stove is to walk from lower to upper, its stroke is short.2, the heat-up rate intensification limit unhappy, Heating temperature is 1800 ℃, and this makes the energy consumption of producing than not high its quality that influences of vanadium nitride product apparent density big and that produced.3, furnace lining Yin Gaowen in the body of heater and nitrogenize phenomenon, the normal appearance is out of shape and damages, and causes producing de-stabilising effect output.4, build stove cost height, upkeep cost height, maintenance interval are long.During maintenance, need full stove stop to produce, whole maintenance, this make the upkeep cost height, servicing time is long and greatly influence annual production.
Summary of the invention:
The purpose of this utility model is, at the in use existing deficiency of existing pushed bat kiln, and propose in a kind of quick heating, intensification limit height, stove the utilization of CO gas fully, build that the stove cost is low, upkeep cost is low, the maintenance interval is short, the device of production stable manufacture process alloy of vanadium nitride.
Can realize the purpose of this utility model by following technical proposals, a kind of device of making alloy of vanadium nitride, comprise furnace shell, it is characterized in that, one crucible is located in the furnace shell, and crucible perisporium and bottom are by insulation furnace lining parcel, and the crucible upper end is provided with insulation bell and metal bell successively, the perisporium of insulation furnace lining is provided with the Medium frequency induction coil, is provided with the nitrogen inlet pipe of leading in the crucible in the bottom of furnace shell.
For grasping the pressure and temperature in the stove, be provided with weather gage at the top of furnace shell, be provided with thermoscope in the bottom of furnace shell.
Be the convenient alloy of vanadium nitride of making in the crucible in the stove that takes out, be provided with body of heater is unsettled and can make the turndown device that motor and transmitting gear be made of of body of heater in the vertical surface rotation at the furnace shell middle part.
Effect of the present utility model is: 1, the body of heater of this device is vertical, and it can make the CO gas in the stove be fully used.Because the CO gas that produces in stove is to walk from lower to upper, body of heater is vertical, and its stroke is long, in its stroke can with the V in the stove
2O
5Effectively make it change into V in conjunction with also producing reaction
2O
32, the heat-up rate intensification limit fast, Heating temperature can be increased to 2000 ℃, and this can reduce the energy consumption in the production and vanadium nitride product apparent density is increased to 4000-5000g/cm
3This mainly is the change of type of heating, and existing apparatus is the conventional heating of electric stove wire, and this device is the intermediate frequency coil heating.3, the furnace lining in the body of heater is difficult for deforming and damaging, because be provided with crucible in body of heater, it shields to furnace lining, can make to produce to stablize.4, it is low to build the stove cost, and upkeep cost is low, the maintenance interval is short.The Yin Ben device constitute by several parts and volume little, in the time of keeping in repair, only need to change and can resume production to certain parts, the parts of repairing are repaiied after changing again.This makes, and upkeep cost is low, the maintenance interval shortens dramatically and influence minimum to production.
Below in conjunction with embodiment and accompanying drawing the utility model is further set forth:
Description of drawings:
Accompanying drawing 1 is the utility model synoptic diagram (broken section).
Embodiment:
Referring to accompanying drawing 1, the outside of body of heater is a furnace shell 1, and furnace shell 1 is built-in with crucible 2.Crucible 2 perisporiums and bottom are by insulation furnace lining 3 parcels.The perisporium of insulation furnace lining 3 is centered on by Medium frequency induction coil 4.Crucible 2 upper ends are provided with insulation bell 5 and metal bell 6 successively, are provided with the nitrogen inlet pipe 7 of leading in the crucible 2 in the bottom of furnace shell 1.For grasping the pressure and temperature in the stove, be provided with weather gage 8 at the top of furnace shell 1, be provided with thermoscope 9 in the bottom of furnace shell.Be the convenient alloy of vanadium nitride of making in the crucible 2 in the stove that takes out, be provided with body of heater is unsettled and can make the turndown device 10 that motor and transmitting gear be made of of body of heater in the vertical surface rotation at furnace shell 1 middle part.
