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. When quenching with conventional quenching oil, problems such as soft spots, low hardness, poor hardening depth always occur in thick and large workpieces or poor hardenability workpieces. KERUN KR128 fast quenching oil can avoid the above problems and obtain high and even surface hardness and enough hardening depth.
 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.

Product Features:
1.The vapor film stage is short, and the cooling rate is fast in high and medium temperature, with appropriate cooling rate in low temperature.
2.For large and medium workpieces, both high and even surface hardness and sufficient hardening depth can be obtained, meanwhile it can control the workpieces very well from distorsion during quenching.
3.Good thermal oxidation stability can maintain long-term stable cooling characteristics, thus its service life is long.
4.Bright, low oil consumption, and low use cost.
