Abstract
The invention belongs to the technical field of metal-material heat treatment, and particularly relates to a novel metal heat treatment method. The heat treatment method includes the steps that a pretreatment channel and a heating channel are formed in a heating cylinder, and a feeding opening and a discharging opening are formed in the heating cylinder; a liquid cavity is formed in the pretreatment channel, and protecting liquid is arranged in the liquid cavity, and is sprayed to workpieces entering the liquid cavity from the feeding opening through a spraying head; the sprayed workpieces are put into the heating channel and heated under protection of nitrogen; the heated workpieces are taken from the heating cylinder to be precooled in air to be at the certain temperature, then put into quenching cooling media and cooled. Under the conditions that the hardness of quenched workpieces and the depth of a hardening layer is not decreased, the heat stress of the workpieces can be greatly reduced, and deformation and cracking can be avoided. The heat stability of the metal can be improved through the protecting liquid, dirt can not be generated in the heating process, and discoloring can not be generated during heating.
Description
Technical field
The invention belongs to technical field of metal material heat treatment, be specifically related to the heat treatment method of a kind of novel metal.
Background technology
During metal heat treatmet, one improves metal material and the technique of goods (such as machine parts, instrument etc.) performance thereof.It refers to metal or alloy be heated to uniform temperature in the solid state, keeps certain time, it is warmed up to uniform temperature again, keeps several processes such as certain time, final purpose brings it about corresponding deformation, become various organizational structure, thus a kind of heat processing technique of the serviceability required for obtaining.Different firing rates, different temperature retention times and the different types of cooling, just constitute different Technologies for Heating Processing, it is seen then that in Technology for Heating Processing, and the control accuracy of temperature is the key determining thermal treatment quality quality.
For what current heat treatment step generally existed, inadequate to uniformity during long and thin metal parts quenching, and often have the problem such as cooling of distortional stress.As expected higher metal parts hardness or enough wear-resisting intensity, need workpiece is carried out heat treatment.The result of heat treatment is the change of part material structure, and the face-centered cube Y lattice of the highest carbon austenitic thin plate changes over the body-centered cube Q lattice of ferrite thin plate.Except temperature and the change of original structure, have impact especially to desired treatment results is the rate of cooling of the part of heating, and the kind of the hardening media used for this.The order risen by rate of cooling is enumerated, and the hardening media of employing mainly has gas, oil or water.
In order to reach to be bordering on identical quenching intensity with oil or water when with gas quenching, it is desirable to higher air velocity.And cause surface of the work to cool down unevenly, and thus tension force occurring, result may deform and even ruptures.First being longilineal workpiece, such as axle, deformation substantially and can make these workpiece not make us full waste product for becoming economically especially owing to most tolerance is the least.
Summary of the invention
For overcoming the defect existing for prior art, the present invention provides the heat treatment method of a kind of novel metal, it is possible to solve above-mentioned technical problem.
The invention solves the problems that its technical problem be the technical scheme is that the heat treatment method designing a kind of novel metal, carry out the most successively:
Step one: provide cartridge heater, arranges pre-processing channel in cartridge heater and adds the passage of heat, arranging feeding mouth and discharging opening on cartridge heater；
Step 2: arrange sap cavity on pre-processing channel, arranges protection liquid in sap cavity, and protection liquid is sprayed to the workpiece entered from feeding mouth by shower nozzle；
Step 3: the workpiece after spraying is put into and added the passage of heat, heats under the protection of nitrogen；
Step 4: after heated parts is taken out from heating bucket, carry out pre-cooling in atmosphere, be cooled to uniform temperature in advance, place in quenching medium and cool down.
As the further prioritization scheme of the present invention, each raw material and the consumption (mass fraction) thereof of the protection liquid described in step 2 be:
As the further prioritization scheme of the present invention, the consumption (mass fraction) of each raw material is:
As the further prioritization scheme of the present invention, the quenching medium described in step 4 is: 10% sodium-chloride water solution, 20 DEG C.
The present invention is had the beneficial effect that
1, the present invention under conditions of the hardness not reducing quenching workpiece and depth of hardening zone, can make the thermal stress of workpiece be greatly reduced, it is possible to avoids deforming and ftractureing.Protection liquid can make metal improve its thermal stability; and dirt will not be produced in heating process, be heated and variable color will not occur, by waterborne acrylic polyurethane surface paint, workpiece be had the strongest adhesive force; meanwhile, quenching will not occur oxidation and decarburization phenomenon.Its rate of cooling can be improved by quenching medium.
