● During the high-temperature cooling phase, it has a fast and uniform cooling rate. During the convection cooling phase, the cooling rate is uniform and slow, which ensures hardening of thick-section workpieces while minimizing quenching deformation.
● Specially treated base oil and compound additive technology ensure stable performance and long service life. Tests show that the cooling characteristics remain basically unchanged after long-term use.
● High flash point and moderate viscosity. Under the same working conditions, oil consumption during quenching is low, reducing operating costs.
● Contains special wetting agents for fast wetting and uniform cooling of the workpiece surface. After quenching, the surface of the workpiece is uniform in color and smooth.
● Low volatility, does not affect the furnace atmosphere when used in protective atmosphere or carburizing quenching.
● Contains unique antioxidants. After long-term use, sludge formation is minimal, and residual oil is easy to clean. The filters, screens, and oil agitation systems in the quenching oil cooling circulation system remain clean and unobstructed.
