Abstract

The invention provides a device for monitoring PAG water base quenching medium cooling performance on line. The device comprises an automatic cooling speed monitoring instrument, the automatic cooling speed monitoring instrument is connected with a control PC, the control PC is connected with a transmission device in a control manner, and a detecting sensor is then arranged on the transmission device; the detecting sensor is placed in a heating furnace for preheating; and a detecting opening of the detecting sensor is further arranged on the side edge of the heating furnace and corresponds to the portion above a PAG water base quenching medium. According to the device, the transmission device is used for placing the detecting sensor into the heating furnace for preheating, then the detecting sensor is placed into the PAG water base quenching medium to conduct on-line monitoring, the simulation effect is achieved by the device, and the truth of monitoring results is conveniently guaranteed.

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...
