Product Description

Product introduction:
With the development of automobile, tractor manufacturing industry and large-scale mining equipment, the size and weight of heat-treated parts are increasing. In order to improve production efficiency, the quenching amount of primary parts is increasing, and continuous quenching automatic line is emerging, which leads to the development of high speed quenching oil. Fast quenching oil is quenching oil with additives added, and the cooling speed is faster than ordinary quenching oil. Kerun's fast quenching oil has strong cooling capacity, high temperature cooling speed and moderate low temperature cooling speed, which can not only make the workpieces obtain high and uniform surface hardness and enough hardening layer depth, but also can better control the quenching deformation, and the surface of the workpieces after quenching is easy to clean, with good thermal oxidation stability and long service life. Workpieces of big or thick shape always get soft points on surface, low hardness, thin hardness layer if quenched in common quenching oil. But questions above would be improved or avoided If quenched in fast quenching oil KR115, workpieces will get high and uniform surface hardness and enough hardness layer.

Product Features:

1.Short vapor film stage, fast cooling at high and medium temperature stage, and has an appropriate cooling at low temperature stage.
2.For medium and large workpieces, high and uniform surface hardness and enough hardened depth can be obtained, and the deformation of workpiece can also be well controlled.
3.Good thermal oxidation stability and long service life with stable cooling character.
4.Nice brightness, low oil consumption and low use cost.
