Abstract
The utility model provides a device monitored is carried out at water base hardening media cooling performance of wire pair PAG, including the cold fast automatic appearance of monitoring, the cold fast automatic appearance of monitoring is connected with the control PC, and control PC control connection has transmission, the last detection sensor that is equipped with again of transmission, detection sensor then places and preheats in the heating furnace, the side of heating furnace still is equipped with detection sensor and detects the mouth, and detection sensor detects mouthful water base hardening media of a corresponding PAG top. The utility model discloses utilize transmission to place detection sensor and preheat in the heating furnace, and then carry out on -line monitoring in placing the water base hardening media of PAG, make its effect that reaches emulation to the authenticity of the result that the assurance was monitored.
Description
Technical field
The utility model belongs to technical field of metal heat treatment, relates to a kind of device monitored PAG water-based quenching medium cooling performance online.
Background technology
Current PAG water-based quenching medium is nontoxic due to it, smokelessly, do not burn, physical property that anti-aging, life-span is long, and its speed of cooling is between water and oil, there are higher stability, defoaming and rustless property, cooling power can carry out with the change of concentration the advantage that adjusts within the specific limits, cooled region between its cooling power overing number to oil, suitability is high; Be widely used in the treatment production of structural carbon steel, carbon tool steel, middle structural low alloy steel, spring steel, converted steel.
In the extensive use procedure of PAG water-based quenching medium, occurred some problems, as after production for some time, the ratio of workpiece hardening crack increases gradually.Trace it to its cause, be that the cooling rate of PAG water-based quenching medium there occurs change and do not identified in time, fail to take appropriate measures in time.Workpiece under quench cooled after, be attached on polymkeric substance on workpiece again can back dissolving in hardening liquid.Back dissolving needs the time, and produce in often wait just workpiece is taken out from hardening liquid completely less than polymkeric substance back dissolving.Like this, in the liquid taken out of of workpiece PAG polymer content often higher than the content in hardening liquid used.For a long time, after a large amount of workpiece quenching, in hardening liquid, the relative concentration of PAG is just inevitable reduce gradually, and the concentration of other additive component raises relatively gradually.Because general factory all adopts refractometer to measure the concentration of hardening liquid, this concentration is the summation of PAG and various additive concentration, fails to reflect truly the concentration of PAG, causes hardening liquid speed of cooling faster, causes workpiece hardening crack to be inclined to and increase.
The cooling performance of PAG quenchant and the concentration of PAG have close relationship.During production, hardening liquid cooling rate measures and may occur the situation that cooling rate is too fast not in time.Cooling rate is too fast, easily makes workpiece deform in quenching process or ftracture.For ensureing workpiece quenching quality, avoiding bulk article to scrap, affecting enterprise and producing, the cooling rate of hardening liquid must be monitored in time.
In existing PAG water-based quenching medium Managed Solution; because cooling rate measures not in time; usually there will be water-based quenching medium and forget multiple situations such as adding or add less; the ill effect that product batch is scrapped can be caused time serious; be tantamount to the normal production having delayed enterprise, add the running cost of enterprise.
Cooling power and the PAG concentration of PAG water-based quenching medium have great relevance, the essence of PAG water-based quenching medium is the cooling power being regulated medium by PAG, to reach processing requirement, and the monitoring of PAG water-based quenching medium cooling power, way traditional in enterprise detects hardening liquid concentration by refractometer, determines hardening liquid whether suitable for producing.And the concentration deviation that this change can not effectively avoiding PAG water-based quenching medium in use to exist and other pollutions cause refractometer to survey, thus have impact on quenching quality, also do not reflect the cooling power that hardening liquid is real in time.
Summary of the invention
The utility model is intended to solve the monitoring management to on-the-spot PAG water-based quenching medium, optimize the management process of PAG water-based quenching medium, by test water-based quenching medium cooling performance, monitoring and reminding is carried out to the cooling performance of on-the-spot PAG water-based quenching medium, a kind of device online PAG water-based quenching medium cooling performance monitored of special proposition.
For this reason, the technical solution of the utility model is: a kind of device monitored PAG water-based quenching medium cooling performance online, comprise cooling rate automatic monitoring instrument, cooling rate automatic monitoring instrument is connected with control PC, it is characterized in that: controlling PC control linkage has transmission mechanism, and transmission mechanism is provided with acquisition sensor again; Acquisition sensor is then placed on preheating in process furnace.
Further improvement is: the side of process furnace is also provided with acquisition sensor and detects mouth, and acquisition sensor detects above the corresponding PAG water-based quenching medium of mouth.
Beneficial effect:
The utility model utilizes transmission mechanism that acquisition sensor is placed on preheating in process furnace, and then is placed in PAG water-based quenching medium and carries out on-line monitoring, makes it reach the effect of emulation, to ensure the verity of the result monitored.
This device does not adopt traditional refractometer to control on-the-spot PAG water-based quenching medium concentration, but carry out the detection of regular timing automaticization by the method (GB/T30823-2014) measuring quenching oil cooling performance by industry to the PAG water-based quenching medium of onsite application, and detected result and existing processing requirement are contrasted, when surveyed PAG water-based quenching medium key index 300 DEG C of speed of cooling are not within the scope of set processing requirement, this equipment will automatic alarm; Remind related personnel add PAG stoste or add water, thus reach the monitoring realized on-the-spot PAG water-based quenching medium, so that better stably manufactured.
Optimize the management process of PAG water-based quenching medium, Aulomatizeted Detect monitoring is carried out to the cooling performance at PAG water-based quenching medium scene, ensure that the normal continuous seepage of PAG water-based quenching medium uses, ensure that its cooling performance meets manufacturing technique requirent, ensure quality product.
By the use of this device, optimize the Managed Solution of PAG water-based quenching medium, ensure that cooling performance when PAG quenchant uses, better ensure that the quality of product, the cooling performance of quenchant can be reflected in time, greatly reduce the product quality problem caused because the control of PAG water-based quenching medium cooling rate is improper.
