From;    Author:Stand originally
International Organization for Standardization (ISO) TC28 subcommittee offerred lube of ISO/DIS 6743/14 lubricant, industry and related goods 1993 (L kind) classification - the 14th part: U group (heat treatment) . Our country consults cost JIS - the classified level that K2242-80 standard raised SH0564-93 heat treatment oil. Method of international standard classification is below:

1, heat treatment uses oil: The oil of some breed is very easy by water rinse out, because broken emulsion was joined in oily recipe, these oil are tasted can call " solubility is oily " , manufacturer can ask to decide this kind of oil according to the user.

(1) Leng Cuihuo (< 80 ℃ ) : A fast quenching oil, UHA; B is common (normal) quenching oil, UHB.

(2) half heat quenchs (30 ℃ - 130 ℃ ) : A fast quenching oil, UHC; B is common (normal) quenching oil UHD.

(3) heat quenchs (130 ℃ - 180 ℃ ) : A fast quenching oil, UHE; B is common (normal) quenching oil, UHF.

(4) high temperature quenchs (180 ℃ of > ) : A fast quenching oil, UHG; B is common (normal) quenching oil, UHH.

(5) vacuum quenchs, UHV.

(6) other, UHK.

2, heat treatment uses water:

(1) the surface quenchs: A water, UAA; B quenchs quickly used hydrous liquid, UAB; C is slow fast quench used hydrous liquid, UAC.

(2) whole quenchs: A water, UAA; B quenchs quickly used hydrous liquid, UAD; C is slow fast quench used hydrous liquid, UAE;

(3) other: UAK.

3, processing uses melt salt:

(1) 150 ℃ - 500 ℃ : Frit salt (150 ℃ - 500 ℃ ) , USA;

(2) 500 ℃ - 700 ℃ : Frit salt (500 ℃ - 700 ℃ ) , USB;

(3) other: USK.

4, heat treatment uses gas: A air, UGA; B neuter gas, UGB; C reductive gas, UGC; D oxidation gas, UGD.

5, fluid-bed: UF.

6, other: UK.
