Bright quenching oil

Abstract

The invention belongs to the technical field of quenching oil, and provides bright quenching oil comprising, by weight, 60%-80% of base oil, 1%-15% of a cooling accelerator, 1%-15% of a brightener, 1%-15% of a high-low temperature antioxidant, 1%-15% of a dispersant and 1%-20% of BS bright oil. The BS bright oil is added on preparation components of the quenching oil, and the BS bright oil has thebeneficial effects of being clear, transparent, high in viscosity, high in density, high in corrosion resistance and the like; because the boiling point of mineral oil rises and the viscosity of themineral oil is increased while the density of the mineral oil is increased, when high-temperature (800-1000 DEG C) workpieces enter an oil pool, boiling is achieved in advance, deposited carbon and other impurities can be effectively prevented from accumulating on the surfaces of the workpieces, and the aim of increasing the brightness degree of the surfaces of the workpieces can be achieved; andby adding 120 BS bright oil or 150 BS bright oil, the bright effect of quenching can be improved, and the quenched workpieces can reach or approach the quenching primary color.

Description

technical field [0001] The invention belongs to the technical field of quenching oil, in particular to bright quenching oil. Background technique [0002] Quenching oil is a kind of process oil, which is used as a quenching medium; there are various kinds of quenching oils on the market, mainly divided into ordinary quenching oil, high-speed quenching oil, bright quenching oil, and vacuum quenching oil; but the above quenching oils all exist One problem is that the bright effect of quenching is not ideal, and the workpiece cannot reach or approach the original color of quenching. Contents of the invention [0003] The invention provides a bright quenching oil, which can solve the problems pointed out in the background technology. [0004] A bright quenching oil, comprising the following components in weight percentage: base oil 60-80%; refrigerant 1-15%; brightener 1-15%; high and low temperature antioxidant 1-15%; dispersant 1-15%; BS bright oil 1-20%.
