Abstract
The invention discloses a kind of high-performance quenching oils, belong to quenching medium field.Oil base quenching oil raw material prepared by the present invention, is influenced by benzene ring substitution group form and with carbon atom number, and the linear chain structure pour point having is low, thermostability is more preferable, and due to the polarity phenyl ring of introducing, the lubricity and dispersion performance of oil base are improved；The cooling adjustment additive of preparation reduces the sub-cooled speed of water, reduce deformation and the cracking of workpiece, and when temperature drops to cloud point or less, the cooling adjustment additive of precipitation is redissolved in water, and reach the temperature condition in quenching process, it prevents from overheating the damage to workpiece；The flash-point adjustment activating agent of preparation prevents from forming gel and quenching oil being made to lose effect so that the viscosity of oil base is adjusted, and improves the heat resistance of oil base to improve flash-point and burning point, increases quenching oil service performance.The present invention solves the problems, such as that current quenching oil poor cooling performance, flash-point are low.
Description
Technical field
The present invention relates to quenching medium technical fields, and in particular to a kind of high-performance quenching oil.
Background technique
Thermo-chemical treatment is that metal or alloy workpiece will be placed in the active medium of certain temperature to keep the temperature, and is made a kind of or several
Kind element penetrates into its surface layer, to change its chemical component, tissue and the heat treatment process of performance.Thermo-chemical treatment utilizes chemistry
Reaction, sometimes dual-purpose physical method change steel part surface layer chemical component and institutional framework, more better than homogeneous material to obtain
The metal heating processing technology of technical economic benefit.It all sprouts since the failure and destruction of machine components are most of in superficial layer, it is special
Not may cause the part to work under the conditions ofs abrasion, fatigue, metal erosion, oxidation etc., the performance of superficial layer is particularly important.Through
The steel-iron components for crossing thermo-chemical treatment need to cool down by quenching, i.e., under high temperature red heat state, austenite structure quickly immerses
In hardening media (oil) with suitable cooling velocity, it is just able to achieve every comprehensive mechanical performance that part reaches needs, from
Austenite structure is transformed into martensite, and part does not crack and keep the deformation of very little.Water ancient is quenched as a kind of
Fiery medium there is the disadvantages of workpiece size deformation after quenching is larger, workpiece surface is oxidizable, be not suitable for precise measure, small
The mass of type component quenches operation.Some good steel alloys of harden ability often require that the hardness for improving surface layer after quenching
And wear-resisting property, while the core toughness of workpiece need to be kept, such requirement is then not achieved using the stronger water of hardening power.Changing
It learns heat treatment and is widely used current, use water as hardening media, there is easily evaporation, easy to damage be heat-treated set under high temperature
It is standby, easily lead to the factors such as disastrous accident occur under enclosed environment, use water gradually decreasing as the occasion of hardening media.Oil
The boiling point of fundamental mode hardening media is much higher than water, and 100 DEG C of whens will not generate a large amount of steam bubbles, at quenching workpiece chilling initial stage, is easy to
Heat exchange and reduction quenching workpiece surface soft spots, not volatile characteristic are suitble to the thermo-chemical treatment quenching of workpiece, even if micro-
Amount volatilization, volatile matter are also easy to burn, and serious oxidation behavior, therefore oil type quenching oil will not be generated to quenching workpiece surface
It is the main cooling medium of current heat-treatment quenching.In course of industrialization, between past decades, many quenching oils used are still
Using machinery oil, such as No. 15 machinery oil, No. 32 machinery oil seldom use special quenching oil as cooling medium.Due to machinery
Oil is complex in composition, and the inside, which is contained, does not remove the undesirable substances such as clean nitride, sulfide, phosphide, oxygen compound, a side
Face, at high temperature, machinery oil service life can shorten, and use cost can rise；On the other hand, under different hardening heats,
It may result in quenching cooling rate to have greatly changed, influence quenching workpiece quality；The machinery oil of additive is not added for third,
It is only suitable for the not high workpiece quenching of simple shape, performance requirement, for requiring the quenching miniature workpiece of core high rigidity, Huo Zheyao
The quenching large-scale workpiece of high surface hardness is sought, machinery oil is not enough to reach this requirement；4th, mechanical oil flash point is lower, in high temperature
When quenching, a large amount of smog easily occur, deteriorate operating environment and endanger operator's health, therefore, at more and more heat
Reason company has eliminated machinery oil, uses professional quenching oil instead and is quenched.Oil type quenching oil is broadly divided into cold oil and hot oil
Two kinds, conventional quenching oil, vacuum quenching oil, fast quenching oil are lower than 100 DEG C, normally referred to as cold oil because of using temperature, and
Isothermal quenching oil, tempering oil are higher than 100 DEG C, normally referred to as hot oil using temperature.The function of cold oil and hot oil, purposes
It is different, cold oil is selected primarily to meeting the needs of quenching workpiece high rigidity, selects hot oil primarily to control quenching
The deformation problems of part workpiece.The purposes of cold oil determines that its cooling rate function is cooling down continuously and healthily in quenching process, isothermal point
Grade quenching oil is mainly used for the quenching of martensite, in order to obtain martensite, isothermal after effectively controlling quenching workpiece deformation and quenching
Hierarchical quenching oil must satisfy two conditions: 1) having certain rapid cooling ability, overcooling austenite is enable to be converted into horse
Family name's body；2) two aspect of the influence of thermal stress or more is reduced to the greatest extent to require to seem contradiction, rapid cooling means the rapidly increase of thermal stress,
And reduce thermal stress, and cooling rate must be alleviated, and therefore, taking into account both sides requires, for comparing fast quenching oil, isothermal point
The formula constituent of grade quenching oil can be more difficult, in terms of being generally only the workpiece quenching for being used in some precision sizes.Cooling performance
It is the important performance of hardening media, its quality directly influences the quality of quenching part, and good cooling performance, which can guarantee, to be quenched
Part after fire has certain hardness and qualified metallographic structure, can prevent part deformation and cracking.When quenching, oily temperature
Degree can be increased instantaneously, if the flash-point and burning point of oil are lower, it may occur however that Ignition Phenomena.Therefore quenching oil answers sudden strain of a muscle with higher
Point and burning point.Quenching oil uses under high temperature and the harsh conditions worked continuously for a long time, it is desirable that oil product have it is good it is anti-oxidant,
Heat resistanceheat resistant is decomposed and the performances such as anti-aging, to guarantee the cooling performance and service life of oil product.The viscosity of oil product and it adhesion amount,
Carrying loss and cooling performance has certain relationship.Under the premise of guaranteeing oil product cooling performance and flash-point, the viscosity of oil product is answered
It is as small as possible, carrying loss can be not only reduced in this way, but also is cleaned convenient for workpiece.Excess water in oil product will affect the heat of part
Quality is handled, causes part soft spots, hardening crack or deformation, it is also possible to cause oil product to splash, accident occurs.But quenching currently on the market
Kerosene flash-point and burning point are low, viscosity is high, poor cooling performance, are not able to satisfy the requirement of people.
