Description
Technical field
The present invention relates to a kind of multi-functional quenching assay dresses of the two-way hydrojet of technical field of metal heat treatment more particularly to top bottom
It sets and method.
Background technology
As the progress of science and technology and industrial development, every profession and trade are all to the demand of quality plate and day
Increase, the quenching-and-tempering process that acquisition quality plate is quenched by immersion liquid is generally used by every profession and trade.In general, high-temperature steel plate exists
When parallel liquid level carries out immersion liquid quenching, surface can continue to generate a large amount of bubble formation vapor membranes, and the vapor membrane that can not be discharged is tight
The heat exchange of high-temperature steel plate surface and coolant liquid is affected again, and then influences entire steel plate cooling velocity and quenching degree.To eliminate
Influenced caused by surface vapor membrane when high-temperature steel plate quenches, in the prior art frequently with increase in quenching tank at a certain angle,
Spacing and the mode of pressure injection quenching liquid break high-temperature steel plate surface hardening vapor membrane, however for unlike material and thickness
Steel plate, the parameters such as spray angle, spout spacing and hydrojet pressure mostly without accurate data standard as reference, can only rely on
The experience of scientific research personnel is set, and then makes the high-temperature steel plate of unlike material and thickness in same quenching apparatus or same material and thickness

Equidimension factor limits, and experimental sample size is smaller, and quenching each surface strength of sample is nearly at the perfect condition of indifference, nothing
Method simulation steel plate really quenches situation, therefore its experimental result data is to the reference value of the practical quenching process parameters in the scene of formulating
It is very limited.
Application No. is 201210253418.4 Chinese patents to disclose " a kind of metal material end hardening testing machine ", leads to
Cross the induction coil of radio-frequency generator and be evenly heated to cylindrical sample is made, at the same on sample center be provided with blind hole with
Thermocouple collects the temperature change of sample, and sink form is made in heating part and water jet is arranged below sample, top is set
Cooling water pipe is set, the jet hardening time is controlled by the water spraying control valve on water pipe among water jet, by being mounted on
The water discharging time of cooling water control valve control cooling water in cooling water tank on cooling water pipe, and used water resource is received
Collection is recycled in cyclic water tank using water pump.The experimental facilities will heat, quenching and cooling integration, and in automation
Realize, have the characteristics that heating time it is short, it is easy to operate and ensure that quench continuity.But the disadvantage is that quenching sample needs to process
For standard-sized cylinder, and end hardening experiment can only be carried out, make the equipment that can not be obtained to plank class sample effectively real
Data are tested, it is even more impossible to simulate live practical quenching situation to provide effective laboratory reference number to change field quenching technological parameter
According to.
Patent disclosed above is all simulated annealing process and obtains the experimental facilities of corresponding data, but each patent is to simulating steel
The process that plate is quenched all haves the shortcomings that different degrees of and deficiency.Therefore, it is relatively strong and being capable of root to develop a kind of versatility
According to requiring the factor for influencing steel plate quenching effect is adjusted or to the experimental provision that quenching mode is adjusted, to studying not
Phase transformation law, inherent mechanism when the steel plate quenching of same material and different-thickness and formulate energy saving and effective big batch life
Produce quenching process parameters and improve product quality etc. is very necessary.
