Background technology
VN alloy is a kind of novel alloy additive, and can substitute vanadium iron is used for the production of micro alloyed steel.Vanadium nitride
The comprehensive mechanical performances such as intensity, toughness, ductility and the thermal fatigue resistance of steel can be improved by making an addition in steel, and it is good to have steel
Solderability.In the case where reaching same intensity, addition vanadium nitride saves vanadium addition 30-40%, and then reduces cost, and vanadium nitrogen is closed
Golden sintering kiln is then a kind of device for producing VN alloy.
Patent No. CN201220251204.9 utility model is added there is provided a kind of VN alloy production with microwave continuous
Hot ejection plate kiln, it mainly include body of heater, charging aperture nitrogen isolating and protecting device, feed conveying device, discharging opening nitrogen every
From protection device, go out material conveying device, conveying frame, microwave source system, water pipe and nitrogen tube, the furnace interior by mutually passing through successively
Logical electrical heating heating zone, microwave heat temperature raising area, microwave heating thermal-insulation area, natural cooling area and forced water cold-zone is constituted；Institute
Microwave source system is stated at microwave heat temperature raising area and microwave heating thermal-insulation area.
Such scheme is complicated, by the use of cooling water as coolant have certain the drawbacks of, it is cold when water pipe bursts
But water can be flowed into kiln, may trigger the danger of fryer；And when producing VN alloy, nitrogen needs in reduction reaction
Heat absorption, therefore need the heat for providing a part to be used for the heating heating to nitrogen in such scheme.
Utility model content
To solve problem above, the utility model is achieved through the following technical solutions：
Heating is from left to right followed successively by inside a kind of vanadium-nitrogen alloy sintering kiln, including kiln body, the kiln body
Area, reaction zone and cooling area, and the heating zone, reaction zone and cooling area be sequentially communicated；The preceding furnace wall of the cooling area is with after
Coiled pipe is provided with the wall of furnace wall vertically；The coiled pipe lower end is connected with nitrogen charging device, and upper end is connected with conduit；It is described to lead
Pipe level is fixedly connected on the side wall of the kiln body, and the other end is stretched into the heating zone.
It is preferred that, the conduit includes inner tube, thermal insulation layer and anticorrosive coat；The thermal insulation layer is wrapped in outside said inner tube；
The anticorrosive coat is wrapped in outside the thermal insulation layer.
It is preferred that, it is additionally provided with valve on the conduit.
Beneficial effect：The utility model is simple in construction, with nitrogen substitute cooling water as coolant can be good to
Kiln is cooled, i.e., nitrogen will absorb a part of heat energy in coiled pipe internal circulation flow, so that cooling down effect is played,
For cooling water, the danger that will not also trigger kiln to burst even if pipe bursting nitrogen；Nitrogen also rises while heat absorption
To the effect heated in itself for nitrogen, it is heated after nitrogen flow into heating zone reaction zone successively by conduit, so as to
Reduce the heat energy of heating heating before a part is reacted nitrogen.In this way, the utility model can greatly save the energy, substantially reduce
Production cost.
Brief description of the drawings

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples, it will be appreciated that this practicality is new
The structure of type is not limited in following examples：
As Figure 1-3, a kind of vanadium-nitrogen alloy sintering kiln described in the utility model, including kiln body 1, kiln body
Heating zone 11, reaction zone 12 and cooling area 13, and heating zone 11, reaction zone 12 and cooling area 13 are from left to right followed successively by inside 1
It is sequentially communicated；Coiled pipe 2 is provided with the preceding furnace wall of cooling area 13 and rear furnace wall wall vertically；The lower end of coiled pipe 2 is connected with nitrogen charging
Device 3, and upper end is connected with conduit 4；The level of conduit 4 is fixedly connected on the side wall of kiln body 1, and the other end stretches into heating
In area 11.
Conduit 4 includes inner tube 41, thermal insulation layer 42 and anticorrosive coat 43；Thermal insulation layer 42 is wrapped in outside inner tube 41；Anticorrosive coat 43
It is wrapped in outside thermal insulation layer 42.Thermal insulation layer 42 can effectively reduce a part heating after nitrogen before heating zone 1 is flowed into
Distributing outside kiln body.Anticorrosive coat 43 can effectively prevent the corrosion of conduit 4, increase the service life of conduit 4.
Valve 5 is additionally provided with conduit 4.Valve purpose is set to be the circulation for timely and effectively controlling nitrogen, in reaction knot
The nitrogen reflux in kiln body 1 is prevented after beam.
Operation principle:Nitrogen at room is filled with into coiled pipe 2 by nitrogen charging device 3, when nitrogen circulates in coiled pipe 2,
The heat in kiln body 1 is absorbed, and heat will be absorbed to for oneself heating heating, the nitrogen after heating heating passes through conduit again
4 flow into heating zone 11 and reaction zone 12.Cooling water is substituted with nitrogen to can be good at carrying out to kiln body 1 as coolant
Cooling, i.e., nitrogen will absorb a part of heat energy in coiled pipe internal circulation flow, so that cooling down effect is played, compared to cooling
For water, the danger that nitrogen will not also trigger kiln body 1 to burst is burst even if coiled pipe 2；Nitrogen also rises while heat absorption
To the effect heated in itself for nitrogen, it is heated after nitrogen heating zone 11 is flowed into by conduit 4 successively, reaction zone 12, from
And the heat energy of heating heating before a part is reacted nitrogen can be reduced.In this way, the utility model can greatly save the energy, greatly
Big reduction production cost.
