Description
Technical field
The utility model relates to a kind of quenching oil cooling rate decline Fast simulation device, is applicable to the Fast Evaluation of quenching oil cooling rate stability.
Background technology
By quenching and corresponding Technology for Heating Processing, change metal inside metallographic structure, can make the mechanical strength properties of metal material obtain the lifting of an order of magnitude left and right; Can obtain the hard and tough Good All-around Property of heart portion of appearance, can make shock resistance, anti stickness wearing and tearing and the antifatigue wearing and tearing of component of machine obtain and promote greatly; Make the hundreds of times of even raisings of thousands of times of acquisition in serviceable life of crucial mechanical part.One of quenching technical hardening media used is exactly quenching oil.Quenching oil is widely used in the Quenching Treatment of the key components and parts (as securing member, gear, axle, bearing, axle sleeve etc.) in the fields such as bridge, wind-powered electricity generation, automobile, engineering mechanical device.
The principle of work of quenching oil, is to remove heat from the surface of workpiece of red heat, and workpiece is lowered the temperature rapidly, obtains corresponding metallographic structure, thereby obtains excellent comprehensive mechanical performance.The cooling velocity of quenching oil is the key index that quenching workpiece obtains good metal structure and mechanical property.For the workpiece of a certain specific materials, shape, size, the cooling velocity of quenching oil is had to a critical requirement, the cooling velocity of quenching oil is only higher than this critical value, and quenching workpiece could obtain the mechanical property of rationality; Otherwise by defective, there are substandard products in the mechanical property of quenching workpiece.Because the environment for use of quenching oil is severe, the thermal shock of the workpiece of 800-900 DEG C of high temperature to quenching oil, can make the structure of matter generation cracking decay of quenching oil, thereby the cooling rate of quenching oil is failed.In the time that the cooling rate of quenching oil drops to below Critical cooling speed, will make the metallurgical structure of quenching workpiece and mechanical property defective.The cooling rate stability of quenching oil is the quality of a particular importance of quenching oil.
Have for evaluation method and the evaluating apparatus of quenching oil quality stability at present: 1, SH/T 0219 quenching oil thermal oxidation stability method is quenching oil thermal oxidation stability tester for the experimental provision of simulated annealing oil quality decay accordingly.This device is mainly used for simulated annealing oil under the condition of thermal oxide, generates the decay process of acid, greasy filth, carbon distribution.This and the quenching oil cracking decay situation under red heat metal fever percussive action is inconsistent, the effectively process of the cooling rate of simulated annealing oil decay.2, use I. C. engine oil greasy filth carbon distribution and generate the method that tendency is evaluated, SH/T 0300 crankcase experimental analogic method, is coking tendency test instrument for simulating the experimental provision of oil quality decay accordingly.Quench and generate the generation tendency of negotiating to borrow for evaluating quenching oil greasy filth carbon distribution at some.3, also have in addition acid number tester, carbon residue analyzer, oil product saturation degree test (ultraviolet test, bromine valency and bromine index test).These method and apparatus do not have corresponding relation with the decline of cooling rate above.Relevant with the cracking of quenching oil raw material have thermogravimetric and differential thermal analysis and a relevant device.But be just used for evaluating the cracking temperature of raw material, the single raw material cracking stability of can grading.And can not evaluate the stability of quenching oil compound.For example, the quenching oil compound that same raw material and different oil products form, their cooling rate stability is different.Therefore, judge at present the cooling rate stability of oil product, see exactly on-the-spot effect.Though on-the-spot practical application effect is the final test stone of cooling rate stability, but can not serve as product export measuring means; Whether the output of quenching workpiece, the size of workpiece, the number of quenching oil mass, quenching oil stir, the reuse of rear cleaning waste oil whether, sample time (samples adding before fresh oil, still add sampling after fresh oil) etc. factor, all can affect the data that quenching oil cooling rate detects.Reflect the stability of cooling rate with effect of field application, the cycle needing is very long, the general short several months, long needs the several years; Evaluation as the decline of quenching oil cooling rate needs method and valuator device more efficiently.For the optimization of quenching oil cooling rate stability, the exploitation of the quenching oil of cooling rate excellent in stability, needs a kind of interference that can get rid of the various factors outside oil product, has rapid and convenient, Simulation evaluation method and instrument accurately.According to analysis above, existing various methodologies and equipment tool are all difficult to meet this requirement.
For importance and the urgency of cooling rate estimation of stability, due to the deficiency of existing method and valuator device instrument, the utility model provides a kind of quenching oil cooling rate decline Fast simulation device.Combine with quenching oil cooling rate checkout equipment, can evaluate fast the cooling rate decline performance of quenching oil compound, in order to the judgment basis as quenching oil cooling rate stability, and as the instrument of the Optimal Development of excellent cooling rate stability quenching oil compound.
