Technical field
The utility model relates to smelts kiln field, and particularly a kind of VN alloy closed smelts kiln.
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.
Utility model content
The purpose of this utility model is to provide a kind of VN alloy closed to smelt kiln, only needs a weld seam, can realize integrally-built being connected and fixed in the manufacture process of smelting kiln section; Top cover is fixedly connected with between two wall shoulders; Like this, the connection of two wall shoulders and top cover, can form closed smelting kiln section.
For achieving the above object, the utility model have employed such technical scheme: described VN alloy closed smelts kiln, is made up of grate, preheating kiln section, smelting kiln section, cooling kiln section, filling heat insulating wall, refractory burner hearth; It is characterized in that: the two ends of smelting kiln section are provided with connection wallboard, wherein one end of preheating kiln section and cooling kiln section is provided with connection wallboard; The two ends of smelting kiln section are connected and fixed respectively by wallboard and preheating kiln section and cooling kiln section; Grate is provided with preheating kiln section and smelting kiln section and cooling kiln section, and wherein, preheating kiln section is connected with grate by end support with cooling kiln section; Smelting kiln section is connected with grate with end plate by crossbeam, and the two ends of crossbeam are welded with end plate; Through refractory burner hearth is provided with in preheating kiln section and smelting kiln section and cooling kiln section; Filling heat insulating wall is provided with between the inwall of refractory burner hearth and preheating kiln section and smelting kiln section and cooling kiln section; Smelting kiln section is made up of two furnace walls be symmetrically welded and top cover, and the top of furnace wall is prefabricated with wall shoulder, and bottom is prefabricated with perpendicular base plate; Being welded and fixed by weld seam along portion of two base plates; Top cover is fixedly connected with between two wall shoulders; The side of one of them furnace wall is provided with heating switch board.
After adopting such structure, smelting kiln section is made up of two furnace walls be symmetrically welded and top cover, and the top of furnace wall is prefabricated with wall shoulder, and bottom is prefabricated with perpendicular base plate; Described prefabricated referring to utilizes bending equipment, is inclined-plane by wall shoulder folding, is the vertical plane of 90 ° by base plate folding, being welded and fixed by weld seam along portion of two base plates; Like this, only need a weld seam in the manufacture process of smelting kiln section, integrally-built being connected and fixed can be realized; Top cover is fixedly connected with between two wall shoulders; Like this, the connection of two wall shoulders and top cover, can form closed smelting kiln section.Its good effect is, airtight performance is good, handling ease, and process velocity is fast, good looking appearance.
In addition, the two ends of smelting kiln section are connected and fixed respectively by wallboard and preheating kiln section and cooling kiln section; Arbitrary parts wherein can be convenient for changing, be conducive to maintenance and maintenance that VN alloy closed smelts kiln, improve service life, saved processing cost.
