Intermediate frequency heating process in crankshaft forging production line, after the crankshaft blank is heated, the oxide scale produced on the surface of the blank is a major cause of the surface quality defects of forged products，for precision forgings with relatively large non-machined surfaces, oxide scale has more significant impact on the surface quality of the products. This requires Descaling machine to be used in crankshaft forging production line.

High-pressure water jetting is a common method of descaling in many countries, due to the high investment, relatively few applications in China, not much used in the forging industry, what we can see is the ultra-high pressure equipment customized by Descaling Technology for our old customers. The pressure of the water pump used in the traditional high-pressure water descaling device is very high, frequent start and stop use of pumps and nozzles are easy to wear, in addition to the high cost of imported pumps and nozzles, So it is extremely difficult to promote in China’s forging industry.
