Abstract
The utility model provides a novel nitrogenize oxidation furnace, including furnace body, crucible, bell and the work or material rest in arranging the crucible in, wherein, the crucible is placed in the furnace body, and the furnace body inboard is equipped with the resistance wire of heating usefulness, the upper end and the bell fixed connection of work or material rest, the bell lid is in the furnace body upper end, the furnace body includes and smelter body outer wall and furnace inner wall vertically welds the check board that a shape is the same at the smelter body outer wall surface, and it has one deck heat preservation iron sheet to cover outside the check board, the heat preservation iron sheet is divided into and erects two sections shape drums and parallel top caps, it has the heat -insulating material asbestos to erect to fill between shape drum and the smelter body outer wall. The heat preservation design of furnace body has improved heat utilization rate, and the outer surface thermal insulation layer of furnace body can offer the system by make full use of for the effective heat with the thermal energy conversion who scatters and disappears.
Description
Technical field
The utility model relates to a kind of oxidation furnace, specifically a kind of novel nitriding and oxidizing stove.
Background technology
Valve nitrogenize generally adopts liquid tufftriding processing, and the tufftride equipment of employing is well formulaStove, interior with crucible splendid attire nitridation salt, temperature control carries out with thermocouple in crucible. This nitrogenize equipment is depositedDeficiency have: 1, liquid tufftriding salt pair crucible has certain corrosivity, when crucible uses oneAfter fixing time, there will be leakage, and saline solution can directly cause brick, resistance wire etc. in body of heater after leakingOoze salt and can not use again, whole body of heater need heavily be built, in the process of brickwork again, need to grow timeBetween and maintenance cost high. 2, temperature fluctuation is larger.
Utility model content
The technical problems to be solved in the utility model be to provide that one expends time in less, maintenance cost is low andThe accurate nitriding and oxidizing stove of temperature control.
For realizing described object, the utility model provides following technical scheme: a kind of novel nitrogenizeOxidation furnace, includes body of heater, crucible, bell and is placed in the bin in crucible, wherein, and earthenwareCrucible is positioned in body of heater, and furnace body inside is provided with the resistance wire of heating use, the upper end of bin and bellBe fixedly connected with, bell covers in body of heater upper end; Described body of heater comprises furnace body outer wall and inboard wall of furnace body,Longitudinally be welded with at furnace body outer wall outer surface the lattice plate that root shape is identical, be covered with one deck outward at lattice plate and protectTemperature iron sheet, described insulation iron sheet is divided into vertical-shaped drum and two sections of parallel top covers; Vertical-shaped drum and stoveBetween external wall, be filled with heat-insulating material asbestos.
The end of described insulation iron sheet dative plate is welded and fixed.
Compared with prior art, the beneficial effects of the utility model are:
1, the INSULATION DESIGN of body of heater, has improved heat utilization rate, and body of heater outer surface heat-insulation layer canLost thermal power transfer for offering system, effective heat energy is fully utilized.
2, because temperature control system adopts mouthful island proper electricity SR of a company Series Intelligent digital control instrument." PID " controls, and temperature-controlled precision is high. Temperature control adopts double temperature double control, temperature control and anti-overtemperatureReport to the police and adopt two to overlap independently system. A whole heating furnace point San Ge district, upper, middle and lower carries out, controlTemperature system is carried out with three thermocouples in crucible, and overtemperature alarm adopts three independences outside crucibleThermocouple carries out temperature acquisition. By the method control, can effectively prevent that equipment is at runningMiddle race temperature, particularly, in blow-on and fused salt process, can prevent temperature overtemperature scaling loss nitridation salt,Therefore temperature control is accurate.
Brief description of the drawings
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is top view of the present utility model;
Fig. 3 is the sectional view of body of heater in the utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, in the utility model embodimentTechnical scheme be clearly and completely described, obviously, described embodiment is only thisUtility model part embodiment, instead of whole embodiment. Based in the utility modelEmbodiment, those of ordinary skill in the art obtain under creative work prerequisite not makingEvery other embodiment, belongs to the scope that the utility model is protected.
Refer to Fig. 1-3, in the utility model embodiment, a kind of novel nitriding and oxidizing stove, bagDraw together body of heater 1, crucible 3, bell 5 and be placed in the bin 4 in crucible 3, wherein, earthenwareCrucible 3 is positioned in body of heater 1, and body of heater 1 inner side is provided with the resistance wire 2 of heating use, bin 4Upper end is fixedly connected with bell 5, and bell 5 covers in body of heater 1 upper end.
The method of nitriding and oxidizing stove operation is: 1, change salt: nitrogenize/saline oxide is put into earthenwareIn crucible 3, heated and salt is melted by resistance wire 2, liquid level extremely from fire door approximatelyTill 150-200mm. 2,, after fused salt is necessarily processed, be raised to the operating temperature of demand,Product to be processed is put into bin 4 again, and puts into nitrogenize/oxidation after front work step is processedIn stove, after the insulation regular hour, come out of the stove.
Described body of heater 1 comprises furnace body outer wall 12 and inboard wall of furnace body 11, outside furnace body outer wall 12Surface longitudinal is welded with 8 lattice plates 15 that shape is identical, is covered with one layer of heat preservation iron outside lattice plate 15Skin 13, described insulation iron sheet 13 is divided into vertical-shaped drum and two sections of parallel top covers; Vertical-shaped drum withBetween furnace body outer wall 12, be filled with heat-insulating material asbestos 14, insulation iron sheet 13 dative plates 15End is welded and fixed.
The INSULATION DESIGN of body of heater 1, has improved heat utilization rate, and body of heater 1 outer surface heat-insulation layer canLost thermal power transfer for offering system, effective heat energy is fully utilized.
