Description
Technical field
The invention belongs to technical field of metal heat treatment, is related to a kind of device being monitored to PAG water-based quenching medium cooling performances online.
Background technology
PAG water-based quenching mediums are nontoxic due to which at present, smokelessly, do not burn, the physical characteristics of aging resistance, life-span length, and its rate of cooling is between water and oil, there are higher stability, defoaming and rustless property, the advantage that cooling capacity can be adjusted with the change of concentration within the specific limits, its cooling capacity covers water to the cooled region between oily, and the suitability is high；Be widely used in carbon structural steels, carbon tool steel, middle low-alloy structural steel, spring steel, carburizing Heat-Treatment of Steel production in.
During PAG water-based quenching medium large-scale uses, some problems are occurred in that, such as after production a period of time, the ratio of workpiece hardening crack gradually increases.Trace it to its cause, be that the cooling rate of PAG water-based quenching mediums there occurs that change, without being recognized in time, fails to take appropriate measures in time.After quenching cools down, the polymer being attached on workpiece understands back dissolving in quenching liquid to workpiece again.Back dissolving needs the time, and often waits in producing and just workpiece is taken out from quenching liquid less than polymer back dissolving completely.So, the content in the liquid that workpiece is taken out of in PAG polymer contents quenching liquid often higher than used.For a long time, after a large amount of workpiece quenchings, in quenching liquid, the relative concentration of PAG is just necessarily gradually lowered, and the concentration of other additive components is gradually risen relatively.Due to general factory all using refractometer determining the concentration of quenching liquid, this concentration is the summation of PAG and various additives concentration, fails truly to reflect the concentration of PAG, causes quenching liquid rate of cooling faster, causes the tendency increase of workpiece hardening crack.
The cooling performance of PAG hardening medias has close relationship with the concentration of PAG.During production, quenching liquid cooling rate is determined and is likely to occur the too fast situation of cooling rate not in time.Cooling rate is too fast, workpiece in quenching process is deformed or is ftractureed.To ensure workpiece quenching quality, it is to avoid bulk article is scrapped, enterprise's production is affected, it is necessary to monitor the cooling rate of quenching liquid in time.
In existing PAG water-based quenching mediums Managed Solution; as cooling rate is determined not in time; usually occur water-based quenching medium forget plus or it is few plus etc. various situations; the ill effect that product batch can be caused when serious to scrap; it is tantamount to delay the normal production of enterprise, increased the operating cost of enterprise.
The cooling capacity of PAG water-based quenching mediums has great relevance with PAG concentration, the essence of PAG water-based quenching mediums is the cooling capacity that medium is adjusted by PAG, to reach technological requirement, and the monitoring of PAG water-based quenching medium cooling capacities, in enterprise, traditional way is to detect quenching liquid concentration by refractometer, determines quenching liquid whether suitable for producing.And this can not be prevented effectively from change that PAG water-based quenching mediums are present in use and other pollutions cause the concentration deviation that refractometer surveys, so as to have impact on quenching quality, also reflect the real cooling capacity of quenching liquid in time.
The content of the invention
Present invention seek to address that the monitoring management to live PAG water-based quenching mediums, the management method of optimization PAG water-based quenching mediums, by testing water-based quenching medium cooling performance, prompting is monitored to the cooling performance of live PAG water-based quenching mediums, it is special to propose a kind of device being monitored to PAG water-based quenching medium cooling performances online.
For this purpose, the technical scheme is that：A kind of device being monitored to PAG water-based quenching medium cooling performances online, including cooling rate automatic monitoring instrument, cooling rate automatic monitoring instrument are connected with control PC, it is characterised in that：Control PC control is connected with actuating device, is provided with detection sensor on actuating device again；Detection sensor is then placed on preheating in heating furnace.
Further it is improved by：The side of heating furnace is additionally provided with detection sensor detection mouth, above detection sensor detection mouth correspondence PAG water-based quenching mediums.
Beneficial effect：
The present invention is placed on detection sensor in heating furnace using actuating device and is preheated, and is then placed in PAG water-based quenching mediums again and is monitored on-line so as to reach the effect of emulation, to ensure the verity of the result for monitoring.
The device does not adopt traditional refractometer to be controlled live PAG water-based quenching mediums concentration, but regular timing automaticization detection is carried out by the method (GB/T 30823-2014) that industry determines quenching oil cooling performance by the PAG water-based quenching mediums to onsite application, and testing result is contrasted with existing technological requirement, when the 300 DEG C of rate of cooling of PAG water-based quenching mediums key index surveyed not in the range of set technological requirement when, the equipment will automatic alarm；Related personnel is reminded to add PAG stock solutions or add water, so as to reach the monitoring realized to live PAG water-based quenching mediums, in order to more preferable steady production.
Optimize the management method of PAG water-based quenching mediums, Aulomatizeted Detect monitoring is carried out to the cooling performance at PAG water-based quenching mediums scene, ensure the normal continuous production and application of PAG water-based quenching mediums, it is ensured that its cooling performance meets manufacturing technique requirent, it is ensured that product quality.
By the use of the device, optimize the Managed Solution of PAG water-based quenching mediums, cooling performance when ensure that PAG hardening medias are used, the quality of product is ensure that preferably, the cooling performance of hardening media can be reflected in time, greatly reduce and improper and caused product quality problem is controlled because of PAG water-based quenching mediums cooling rate.
