Abstract
The invention discloses a water-soluble quenching liquid, and relates to the technical field of metal heat treatment in mechanical industries. The water-soluble quenching liquid comprises, by weight, 20-70% of polyalkylene glycol, 8-10% of sodium benzoate, 0.1-10% of a PH regulator, and the balance being water. The water-soluble quenching liquid can overcome the problems of workpiece quenching deformation and cracking or soft point appearance caused by too fast low temperature cooling speed when steel components are cooled by quenching.
Description
Technical field
The present invention relates to technical field of metal heat treatment, especially a kind of water-soluble quenching liquid for carbon steel and alloy steel parts quench cooled.
Background technology
At present, the most frequently used in machinery industry heat treatment step quenchant has water-based quenching agent and oiliness quenching medium; Oiliness quenching medium is easy contaminate environment in quenching process, produces a large amount of smog, impacts the health of operator, and in addition, low, the easy presence of fire of mineral oil flash, uses dangerous; Water-soluble quenching agent is by soluble in water for organic polymer solvent, is met the cooling performance of quenching medium by the concentration and temperature adjusting solution.Water-soluble quenching agent possesses high speed of cooling in whole process of cooling, grain refining, crystal formation rule can be impelled in the high temperature cooling stage, be conducive to the use properties of raising work, but at cold stage, there is too high speed of cooling and easily cause workpiece cracking, quenching strain, occur the problem of soft spots.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of water-soluble quenching liquid, and when it can solve steel-iron components quench cooled, subcooling excessive velocities causes workpiece quenching to be out of shape the problem even ftractureing or occur soft spots.
In order to solve the problem, technical scheme of the present invention is: this water-soluble quenching liquid, and the weight percent of each component is:
Polyalkylene glycol 20-70%,
Sodium Benzoate 8-10%,
PH conditioning agent 0.1-10%
All the other are water.
In technique scheme, more specifically technical scheme is: described PH conditioning agent is trolamine.
Owing to adopting technique scheme, the present invention has following beneficial effect:
Speed of cooling of the present invention, between oil and water, which overcomes water slow in middle temperature cooling stages speed of cooling, can form " soft spots " at workpiece surface, and very fast in the cooling of subcooling stage, makes the yielding problem even ftractureed of workpiece.
Embodiment
By embodiment, the present invention is described in further detail below:
Embodiment 1: prepare this water-soluble quenching liquid double centner, gets polyalkylene glycol 20 kilograms, Sodium Benzoate 10 kilograms, trolamine 10 kilograms, and 60 kilograms, water, after above-mentioned substance mixes.
Embodiment 2: prepare this water-soluble quenching liquid double centner, gets polyalkylene glycol 70 kilograms, Sodium Benzoate 8 kilograms, trolamine 1 kilogram, and 21 kilograms, water, after above-mentioned substance mixes.
Embodiment 3: prepare this water-soluble quenching liquid double centner, gets polyalkylene glycol 45 kilograms, Sodium Benzoate 9 kilograms, trolamine 5 kilograms, and 41 kilograms, water, after above-mentioned substance mixes.
