Abstract
The invention discloses a quenching agent, belonging to the field of heat treatment of metals. The quenching agent comprises the following components in parts by weight: 15-20 parts of polyoxyethylene ether, 5-8 parts of triisopropanolamine, 3-7 parts of polyvinyl acetate, 1-4 parts of sodium benzoate, 0.5-2 parts of a defoaming agent and 70-80 parts of water. By applying the quenching agent to the heat treatment of the metals, the high-temperature cooling speed can be effectively increased, the high-temperature cooling time can be prolonged, and the cracking of workpieces can be prevented; furthermore, the quenching agent is safe and environmental friendly in use, extremely low in environmental pollution and cost, and easy to industrially produce.
Description
Technical field
The invention belongs to metal heat treatmet field, specifically, relate to a kind of quenching medium.
Background technology
In order to obtain the steel of different performance, needing to improve the performance of metallic substance, normally heat-treating the workpiece of metal material, conventional thermal treatment process has the heat treating methods such as quenching, tempering, annealing, normalizing.Wherein, quenching refers to and the workpiece being such as heated to austenitic state is quickly cooled to speed more than critical cooling velocity quenching structures such as forming martensite, after quench treatment, can improve the hardness of workpiece.In the process of quenching, the process of cooling of workpiece is generally divided into three phases, namely the boiling point that metallic substance is surrounded by the steam of quenchant first stage (steam film stage), the subordinate phase (boiling stage) of vapor film breakage boiling, the temperature of metallic substance reach quenchant captures the phase III (convection current stage) of heat below by way of convection current, be then cooled to room temperature.
Conventional quenchant has water-based quenching agent and oiliness quenching medium, the feature of water-based quenching agent all has very high speed of cooling in whole process of cooling, can impel in the speed of cooling that the high temperature cooling stage is high and form the tiny workpiece of crystal grain, be conducive to improving the final performance of workpiece, but at cold stage, too fast speed of cooling makes the internal stress of workpiece excessive, therefore easily causes workpiece to ftracture.Compared with water-based quenching agent, the feature of oiliness quenching medium is that the speed of cooling of whole cooling stages is slow, although can prevent workpiece cold stage due to internal stress excessive and cause cracking, but because hot stage speed of cooling is slower, therefore easily cause workpiece crystal grain comparatively large, reduce the performance after workpiece quenching.In addition, traditional oiliness quenching medium is oil based on the mineral oil with petroleum fractions usually, is equipped with additive and forms.The distinctive performance of mineral oil determines and can produce a large amount of smog when quenching, therefore easy contaminate environment, and environment-friendly function is poor.And, the oiliness quenching medium speed of cooling narrow range based on mineral oil.In addition, mineral oil flash is low, and easy initiation fire uses dangerous.
Summary of the invention
the problem that 1, will solve
There is speed of cooling narrow range for existing quenching medium, contaminate environment, use uneasy congruent problem, the invention provides a kind of safety, environmental protection, can cool fast when high temperature and at low temperature time slow down the quenching medium of speed of cooling, effectively can improve workpiece performance, prevent workpiece from ftractureing.
