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. KR238 fast and bright quenching oil, with high cooling speed and stable performance, is especially suitable for quenching large module gear, large section bearing ring, bearing roller, textile workpieces, sewing machine workpieces, hardware tools and other workpieces under protective or controlled atmosphere conditions.
