Abstract
The utility model provides a furnace is exempted from to build by laying bricks or stones by vanadium nitrogen alloy smelting furnace, by the oven top cap, exempt from to build by laying bricks or stones furnace, silicon molybdenum bar, heat preservation stopping, electric heat idol, the end liner brick is constituteed, it includes that a plurality of arranges dome brick and the wall brick and the end brick of butt joint one by one to exempt from to build by laying bricks or stones furnace, during the construction, only need to arrange the butt joint to dome brick and wall brick and end brick one by one, can form a rectangle access structure exempt from to build by laying bricks or stones furnace, need not fill refractory material mud between the seam, can obviously improve construction speed like this and reduce intensity of labour, in the use, the change of very convenient local dome brick or wall brick or end brick also makes things convenient for electric heat even summation silicon molybdenum bar's installation simultaneously. It possesses sealedly and the heat preservation function simultaneously to exempt from to build by laying bricks or stones the peripheral heat preservation stopping of filling of furnace.
Description
Technical field
The utility model relates to VN alloy smelting furnace field, is specifically related to a kind of VN alloy smelting furnace and exempts to build burner hearth by laying bricks or stones.The replacing with convenient local dome brick or nogging or end brick, the beneficial effect facilitating the installation of electroheat pair and Si-Mo rod, sealing and heat-insulating property good.
Background technology
VN alloy and vanadium nitride.VN alloy is a kind of novel alloy additive, can substitute the production of vanadium iron for micro alloyed steel.Vanadium nitride makes an addition to the comprehensive mechanical performances such as intensity, toughness, ductility and the thermal fatigue resistance that can improve steel in steel, and makes steel have good solderability.Reaching under same intensity, adding vanadium nitride and save vanadium addition 30-40%, and then reduce cost.VN alloy can be used for structural steel, tool steel, pipe line steel, in reinforcing bar and cast iron.VN alloy is applied in Aldecor can carry out effective vanadium, nitrogen microalloying simultaneously, promotes the precipitation of carbon, vanadium, nitrogen compound in steel, more effective performance sedimentation strengthening and Grain refinement.VN alloy is the blank be made up of raw material such as vanadic anhydride, carbon dust, activating agents, and under normal pressure, nitrogen atmosphere protection, under 1500 ~ 1800 DEG C of conditions of high temperature, reaction generates VN alloy.Its key processing equipment is continous way atmosphere push pedal high temperature furnace, adopts the heatings such as Si-Mo rod to obtain thermal source.At present, the key processing equipment producing VN alloy is continous way atmosphere push pedal high temperature furnace, and the body of heater of this kiln adopts Plate Welding; The defect existed and deficiency are: 1. weld seam is too much, and manufacturing cost is higher, and service life is shorter, are not easy to maintenance; 2. airtight difficulty, causes poor thermal insulation property, the wasting of resources; 3. the burner hearth of smelting furnace adopts refractory wass to build by laying bricks or stones into, and difficulty of construction is large, is not easy to the replacing of maintenance and burner hearth.
China Patent No. 201220660957.5 discloses a kind of combustion vertical furnace for building element fire resistance test, it comprises body of heater and specimen holder, it is characterized in that: described body of heater is box-like, body of heater foundation adopts the C20 armored concrete terrace of thickness 200mm, trial furnace peripheral region terrace surface smears 1:2 cement mortar, and built-in fitting adopts steel; Combustion vertical furnace sealing property for building element fire resistance test strengthens, and avoids flue gas to leak, and by the state of observation window Real Time Observation testing sample, can ensure that and be conducive to the collection to burning data by the accuracy that combustion furnace is measured.
Utility model content
The purpose of this utility model is to provide a kind of VN alloy smelting furnace to exempt to build burner hearth by laying bricks or stones, the replacing with convenient local dome brick or nogging or end brick, the beneficial effect facilitating the installation of electroheat pair and Si-Mo rod, sealing and heat-insulating property good.
For achieving the above object, the utility model have employed such technical scheme: described VN alloy smelting furnace exempts to build burner hearth by laying bricks or stones, by furnace wall top cover, exempt to build by laying bricks or stones burner hearth, Si-Mo rod, heat insulating stuffing, electroheat pair, end liner brick form; Describedly exempt to build by laying bricks or stones burner hearth and comprise several dome bricks arranging docking one by one and nogging and end brick; It is characterized in that: the top of furnace wall is provided with furnace wall top cover, is provided with heat insulating stuffing in furnace wall, is provided with and exempts to build burner hearth by laying bricks or stones in heat insulating stuffing; Respectively to being connected to nogging between the two ends of dome brick and end brick; The inner side of dome brick is provided with several Si-Mo rods, is equipped with end liner brick in end brick; Several Si-Mo rods are provided with in end brick; The end of Si-Mo rod is arranged on the side of furnace wall by heat insulating stuffing; The opposite side of furnace wall is provided with several electroheat pairs, and the end of electroheat pair is arranged on the inner side at nogging top by heat insulating stuffing.
After adopting such structure, during construction, only dome brick and nogging and end brick need be arranged docking one by one, can be formed rectangular channel structure exempt from build burner hearth by laying bricks or stones; Do not need filling fire resisting material mud between seam, speed of application can be significantly improved like this and reduce labour intensity; In use procedure, the replacing of very convenient local dome brick or nogging or end brick, also facilitates the installation of electroheat pair and Si-Mo rod simultaneously.Exempt to build the heat insulating stuffing of filling burner hearth periphery by laying bricks or stones and possess sealing and heat insulation function simultaneously.
Through practical application, achieve gratifying effect.Its good effect is: significantly improve speed of application, reduce labour intensity; The replacing of very convenient local dome brick or nogging or end brick, also facilitates the installation of electroheat pair and Si-Mo rod simultaneously; Sealing and heat-insulating property good.
