Description
Technical field
The invention belongs to technical field of metal material heat treatment, and in particular to a kind of heat treatment method of novel metal.
Background technology
A kind of technique improving metal material and its product (such as machine parts, tool) performance when metal heat treatmet.It
Refer to and metal or alloy is heated to certain temperature in the solid state, is kept for certain time, then is warming up to certain temperature, keeps a timing
Between etc. several processes, final purpose bring it about corresponding deformation, become various institutional frameworks, to obtain required for
Performance a kind of heat processing technique.Different heating speeds, different soaking times and the different types of cooling, with regard to structure
At different heat treatment process, it is seen then that in heat treatment process, the control accuracy of temperature is to determine the pass of thermal treatment quality quality
Key.
For generally existing in current heat treatment procedure, uniformity is inadequate when to long and thin metal parts quenching, and passes through
Often there is the problems such as cooling of distortional stress.Such as expect higher metal parts hardness or enough wear-resistant strengths, needs
Workpiece is heat-treated.Heat treatment the result is that the change of part material structure, such as high carbon austenitic thin plate the center of area
Cube Y lattices are changed to the body-centered cube Q lattices of ferrite thin plate.In addition to the change of temperature and original structure, at heat
Reason result have especially influence be heating part cooling velocity, and the type of hardening media that uses thus.By cooling speed
The order that degree rises is enumerated, and the hardening media of use mainly has gas, oil or water.
Identical quenching intensity is bordering on with oil or water, it is desirable that higher gas velocity in order to reach when with gas quenching
Degree.And workpiece surface is caused unevenly to cool down, to tension occur, it as a result may deform and even be broken.It is elongated first
The workpiece of shape, such as axis, deformation can be particularly apparent and since most tolerance very little make these workpiece become economically
For do not make us full waste product.
Invention content
To overcome the defects of present in the prior art, the present invention provides a kind of heat treatment method of novel metal, can solve
Certainly above-mentioned technical problem.
The invention solves technical solutions used by its technical problem to be：Design a kind of heat treatment side of novel metal
Method carries out successively as steps described below：
Step 1：Cartridge heater is provided, pre-processing channel and heating channel are set in cartridge heater, are set on cartridge heater
Material mouth and discharge port；
Step 2：Sap cavity is set on pre-processing channel, and the setting protection liquid in sap cavity, protection liquid is by nozzle to from entering
The workpiece that material mouth enters is sprayed；
Step 3：Workpiece after sprinkling is put into heating channel, is heated under the protection of nitrogen；
Step 4：Workpiece will be heated after being taken out in heating bucket, be pre-chilled in air, be cooled to certain temperature in advance, then
It is put into quenching medium and is cooled down.
As a further optimization solution of the present invention, each raw material and its consumption (matter of the protection liquid described in step 2
Amount number) be：
As a further optimization solution of the present invention, the consumption (mass fraction) of each raw material is：
As a further optimization solution of the present invention, the quenching medium described in step 4 is：10% sodium chloride water
Solution, 20 DEG C.
Advantageous effect possessed by the present invention is：
1, the present invention can make the thermal stress of workpiece under conditions of not reducing the hardness and depth of hardening zone of quenching workpiece
It greatly reduces, can avoid deforming and cracking.Protection liquid energy enough makes metal improve its thermal stability, and heated
It not will produce dirt in journey, it is heated to change colour, have to workpiece by waterborne acrylic polyurethane surface paint very strong attached
Put forth effort, meanwhile, oxidation and decarburization phenomenon will not occur in quenching.Its cooling velocity can be improved by quenching medium.
