Nitriding, oxidation all are steel-iron components process of surface treatment commonly used, and these two kinds of technologies are carried out in nitriding furnace, oxidized still respectively usually.Nitriding method is a lot, can adopt different medias such as gas, fused salt, plasma that steel-iron components is carried out nitriding.After nitriding was handled, workpiece surface had higher hardness, intensity and stable stress, makes workpiece have better wear resistance and use properties.Oxidation technology has obtained application in the twentieth century middle period on speedy steel cutting-tool, have good chemical stability based on the oxide film of Z 250, plays antirust, oil storage and reduce the effect of cutting temperature on cutter, increases substantially the life-span of cutter.The beginning of twentieth century end is applied on hot-work die, reducing the mould temperature rise, stores cooling fluid, releasing agent, and improving the anti-seam aspect of performance of mould has good effect.
Steam oxidation is the surface oxidation technology that is usually used in steel-iron components, and steam oxidation is considered to the technology of optimum oxidation at present, and traditional steam treatment stove adopts Boiler Steam.Evaporation forms steam also can directly splash into water in stove after, but steam instability, inhomogeneous in this technology stove has reduced the oxide mass of being produced.
It is the novel process that development in recent years is got up and is applied in industry member that oxygen nitrogen is handled, and its advantage comprehensive and oxidation and nitrogenize is mainly used in cutter, cutlery neighborhood.
Tradition steam treatment stove can not be used for nitriding, and can carry out oxygen nitrogen Combined Processing in nitriding furnace, and two kinds of methods are arranged at present: evaporation forms steam the first splashes into water in gas nitriding furnace after, carries out steam oxidation.It two is to utilize the low-pressure gas nitriding furnace, puts into little air by low-pressure oxidized generation oxide film.But the oxide film that these two kinds of technologies obtain is all relatively more loose, quality is not good, and the former manufacturability is poor.
The utility model content
The purpose of this utility model provides a kind of novel oxygen nitrogen surface heat treatment unit, makes it can carry out gas nitriding, steam oxidation and the thermal treatment of oxygen nitrogen compound surface.
Another purpose of the present utility model provides the intasome device that a kind of compact construction, technology are simple, integrate nitriding and steam oxidation.
The purpose of this utility model realizes by following proposal and means: the utility model oxygen nitrogen surface heat treatment unit mainly includes oxygen nitrogen and handles stove, Steam generating furnace, nitrogen pot and auxiliary equipment, arranged superposed is integrated into one about it is characterized in that oxygen nitrogen processing stove and steam preheating stove, and besieged being arranged in the whole housing case.The steam preheating furnace interior is provided with spiral coil and is positioned at the sweating room at top, and sweating room directly is connected with the furnace chamber that the airtight oxygen nitrogen above it is handled stove; The upper entrance place of steam preheating stove, the ingress that is spiral coil is connected with pipeline, be connected by the outlet of pipe passage with nitrogen pot and Steam generating furnace, on nitrogen pot and exit, the vapour generator top pipeline regulated valve is housed respectively, nitrogen and steam can enter in the steam preheating stove respectively or simultaneously jointly by valve; Near the intersection of both outlet conduits, be provided with control pressure by air pressure table; Oxygen nitrogen processing stove and steam preheating stove are respectively equipped with the thermopair of monitor temperature; Handle furnace roof portion at oxygen nitrogen and be provided with vapor pipe and tensimeter and exhaust gas treating device, the stove inner exhaust gas can be discharged through this exhaust gas treating device; Described device also is provided with the electric control cabinet of control body of heater Heating temperature and gaseous tension.The steam preheating stove adopts Electric heating, and comes control current and temperature by electric control cabinet.
The operating process of oxygen nitrogen surface heat treatment unit of the present utility model is as follows: will carry out surperficial heat treated steel-iron components or workpiece and be positioned in the oxygen nitrogen processing stove, the initial steam that is about 160 ℃ from the temperature of vapour generator enters the sweating room that spiral coil in the electric-heating steam preheating oven arrives the top by pipeline, this moment, steam was preheated to 500-600 ℃, enter oxygen nitrogen then and handle stove, carry out steam oxidation.For guaranteeing the coating mass of mould steel, the ideal temperature of steam oxidation is 500-600 ℃, and impelling it to generate fine and close Z 250 is main oxide film, helps improving the performance that tool and mould uses, and prolongs the life-span of tool and mould.According to arts demand, can carry out oxygen nitrogen Combined Processing simultaneously, can open the valve on the pipeline of nitrogen pot simultaneously, nitrogen by the piping pipeline, is entered steam pipe oven, and then enter oxygen nitrogen and handle stove, carry out nitriding and handle.Tail gas in the stove is discharged through vapor pipe and exhaust gas treating device.
The advantage and the effect of the utility model oxygen nitrogen surface heat treatment unit are described below:
1. the utility model is owing to be integrated into a body of heater with steam preheating stove and oxygen nitrogen heat treatment furnace, compact construction,
Work simplification, and, can further be preheated to steam required owing to be provided with the steam preheating stove
500-600 ℃ of temperature of superheat helps the formation of oxide film, avoided using boiler tubing simultaneously in the past
The calorific loss of the transmission pipeline that steam causes can reduce energy consumption.
2. adopt electrically heated steam preheating stove, steam further be heated to 500-600 ℃ of ideal temperature of superheat,
Can generate fine and close oxide film with this understanding, help improving tool and mould based on Z 250
Use properties, the life-span of prolongation tool and mould.
3. device of the present utility model can carry out nitriding and oxidation in the same heat treatment furnace, oozes as only carrying out gas
Nitrogen then can feed nitrogen; As only need advance steam oxidation then can feed superheated vapour; Can successively feed or with
