Description

technical field

[0001] The invention belongs to the technical field of metal heat treatment, and relates to a device for monitoring the cooling performance of a PAG water-based quenching medium on-line. Background technique

[0002] At present, PAG water-based quenching medium has high stability, defoaming and anti-foaming properties due to its non-toxic, smokeless, non-combustible, anti-aging, long-life physical characteristics, and its cooling rate is between water and oil. rust performance, the cooling capacity can be adjusted with the change of concentration within a certain range, its cooling capacity covers the cooling area between water and oil, and its applicability is extremely high; it is widely used in carbon structural steel, carbon tool steel, Heat treatment production of medium and low alloy structural steel, spring steel and carburizing steel.

[0003] During the large-scale use of PAG water-based quenching medium, some problems appeared. For example, after a...
