Background technique
Many heat treatment process are completed in continuous cooling process, such as the cold annealing of furnace, air-cooled normalizing, water hardening
Deng.In continuous cooling process, overcooling austenite can be carried out perlitic transformation, bainite transformation and martensite transfor mation etc..
It is not in new transformation unexistent in isothermal cooling transformation in continuous cooling process.But austenite
Continuous cooling transformation be different from isothermal transformation.Because continuous cooling process will successively pass through each transformation temperature ranges, therefore can
Several transformations can successively occur.Moreover, cooling velocity is different, it may occur however that transformation it is also different, the relative quantity of various transformations
Difference, tissue and performance because obtained from are also different.The rule of overcooling austenite isothermal transformation can be represented with C curve
Come.Similarly, the rule of continuous cooling transformation can also be showed with another C curve, and here it is " continuous coo1ing C is bent
Line " is also called " thermomechanical curve ".According to English name prefix, also known as " CCT (Continuous Cooling
Transformation) curve ".
To make steel-casting during heat treatment, good metallographic structure, Jin Erti are obtained by cooling velocity appropriate
The mechanical property of high steel-casting, therefore design heat treatment multifunction changable speed cooling system.
Utility model content
The purpose of the utility model is to provide a kind of heat treatment multifunction changable speed cooling systems, by adjusting cooling system
System structure increases variable-ratio blender in tank for coolant, and connection circulation storage liquid case, passes through pump and quenching in tank for coolant outward
Fiery medium is exchanged, and can achieve the effect of cooling speed change cooling and strength cooling, outside setting mobile overhead crane and overhead crane orbit, can
So that steel-casting moves upward or downward, front or back, left or right in a cooling system, steel-casting can be made uniformly to cool down in hardening media, simultaneously
The effect for abolishing steam blanket is improved, to obtain ideal metallographic structure, achievees the effect that improve steel-casting mechanical property.
To achieve the above object, the utility model is implemented with the following technical solutions:
A kind of heat treatment multifunction changable speed cooling system, including tank for coolant, storage liquid case, overhead traveling crane, charging basket, stirring

Suspension hook hang oneself charge basket, steel-casting is placed in charging basket；The blender is mounted in tank for coolant.
The storage liquid case is equipped with cooling device, stores liquid level in liquid case and is lower than outlet tube.
Compared with prior art, the beneficial effects of the utility model are:
1) the utility model can make the steel-casting after heating by overhead traveling crane handling steel-casting, and entrance rapidly and accurately is quenched
In fiery medium.After overhead traveling crane handling steel-casting enters hardening media, it can move upward or downward, front or back, left or right, make steel-casting in hardening media
In can achieve the purpose that it is uniformly cooling.
2) blender is installed in tank for coolant bottom, makes cooling medium in tank for coolant according to a certain direction and speed
It is rotated, so as to destroy in quenching process, the steam blanket generated around steel-casting prevents steel-casting in hardening media
Middle cooling rate is lower than critical cooling rate.Steel-casting is cooled down in quenching process lower than critical cooling rate, can be balanced
Tissue (similar soft tissue).
3) the utility model will store cooling medium and coolant liquid in liquid case using liquid case, inlet tube, outlet tube and pump is stored
Cooling medium in case is interchangeable, and is discharged to the cooling medium of overheat in quenching process and is stored in liquid case, then by low temperature
Cooling medium is input in tank for coolant from storage liquid case, and the cooling medium in tank for coolant is made to keep controllable temperature state at any time.
4) different types of cooling medium, Ru Shui, oil, quenching liquid etc. can be replaced in tank for coolant, in order to allow
Steel-casting is cooled down with cooling velocity appropriate, the metallographic structure for needing steel-casting, to improve the power of steel-casting
Learn performance.
