Definitions
- This invention relates to oil compositions that are useful as quenching oils used in heat treating of metals, particularly ferrous metals such as steel.
- Desired hardness and strength properties of metals are secured by heat treatment of the metal object.
- the properties usually depend upon establishment of certain physical structures in the metal.
- the production of the desired physical structures is obtained by heating the metal to a temperature where the structure is present, then by arresting at the desired point the changes in the internal structure which take place during cooling of the metal from high temperatures. Quick cooling by quenching the heated object in a quenching medium makes it possible to arrest the physical changes at the desired point during cooling.
- Quenching in the quenching medium is carried out in such a manner that the physical changes in the metal are arrested at the desired point, usually at the point at which maximum hardness is obtained. Subsequently, the heat treated and quenched object may be subjected to treatment at lower temperature (annealing or tempering) to provide the desired degree of toughness and ductility.
- mineral oil based quenching fluids have been used. Previously, aqueous quenching media were employed. The aqueous fluids provided extremely rapid cooling setting up excessive amounts of internal stress in the object. Mineral oil based fluids avoided this difficulty, but often did not provide a sufficiently high cooling rate to secure desirable properties in pieces formed of materials having high critical cooling rates to develop maximum strength and hardness or to quench pieces of high mass to surface ratios to develop hardness and strength to maximum depth.
- Durability refers to additive lifetime after being exposed to thermal stressing while consistency relates to constant additive performance over time. Cleanliness is measured using a coker test.
- U.S. Patent 2,340,724 relates to quenching oils comprising a light mineral quenching oil and an oil-soluble, heat stable, high molecular weight iso-olefin polymerization product in a controlled amount adequate to produce a quenching oil composition having an initial 5-second quenching speed of at least 22.0 percent without substantially modifying the stress-reducing characteristics of the oil.

- the quenching oil compositions of this invention typically comprise from about 0.2% to about 10%, preferably to about 5% by weight of the aliphatic polyolefin (2), and a total of from 0.2% to about 10% by weight of a metal salt of hydrocarbyl substituted phenols, salicylic acids and sulfonic acids and alkaline earth metal salts of hydrocarbyl substituted saligenin derivatives, and optionally at least one of hydrocarbyl substituted succinic esters, amides, ester-amides, imides, amine salts, acid-esters, acid-amides, ester-amine salts, amide-amine salts and acid-amine salts, provided that the composition comprises at least one of a metal salt and a succinic derivative.
- the succinic derivatives are present in amounts ranging from about 0.1% to about 5% by weight.
- the composition comprises from about 0.2% to about 5% by weight of the aliphatic polyolefin (2), and (3)(a) from about 0.2%) to about 5% by weight of at least one metal salt wherein the weight ratio of (2):(3)(a) ranges from about 10: 1 to about 1 : 10.
- the composition comprises from about
- This invention also relates to a method of heat treating metals comprising heating the metal to a temperature above its critical temperature and thereafter cooling the metal by immersion thereof into a quenching oil bath comprising the quenching oil composition of this invention.
- the additive components may be incorporated into the base oil as individual components, added thereto in any order.
- the additive components are added to the base oil as a concentrate which comprises the desired additives in appropriate ratios which, when inco ⁇ orated into the base oil, provide a finished quenching oil composition containing the desired amount of each additive.
- compositions of this invention A series of quenching oil compositions is prepared, each member of the series containing 2% by weight of one of additive concentrates 1-5 in Pennzoil/Conoco Excel Paralube 75-HC (75N) oil. A second series is prepared, each member of the series containing 4%> by weight of one of additive concentrates 1-2 and 4-5 in the same oil. A third series is prepared, each member containing 6% by weight of additive concentrates 1-2, and 4-5 in the same oil.
- Each sample is subjected to a one-minute quench test and a 3 hour panel coker test.
- the quench test quantifies the cooling characteristics of the quench oil sample and the panel coker test measures the tendency of the quench oil sample to stain and/or form deposits on hot metal surfaces. Similar results between corresponding heat stressed and unstressed oils samples provide an indication of durability and consistency of the test oils.
- metal ions of, e.g., a detergent
- the products formed thereby including the products formed upon employing the composition of the present invention in its intended use, may not susceptible of easy description. Nevertheless, all such modifications and reaction products are included within the scope of the present invention; the present invention encompasses the composition prepared by admixing the components described above.
