How to save costs and reduce consumption for metal descaling machines
The forging industry knows that the process of descaling is generally carried out after the billet is made. Of course, the process requirements of each forged part are different. Some will remove the scale directly after the round bar comes out of the intermediate frequency furnace, and some will be removed after precision forging. Oxide skin such as the gear industry. So why is there a process of dephosphorization (deoxidation) in the forging process? And why choose descaling equipment to remove the phosphorus?
The descaling equipment mainly uses the heat change, impact, vibration, scouring and other effects generated on the surface of the forging billet by high-pressure water jet. Expanded, and partially warped, the deformed iron oxide scale is easily broken under the impact of high-pressure water jet; high-pressure water enters between the iron oxide scale and the forging billet to generate a water wedge, which plays the role of peeling off the iron oxide scale, and at the same time, enters The water between the iron oxide scale and the forging billet will explosively evaporate into steam at high temperature to accelerate the detachment of the oxide scale; the residual flow of the water jet will wash the broken and peeled iron oxide scale from the surface of the forging billet to realize the phosphorus removal on the surface of the forging billet. Skin removal. This is why the phosphorus skin must be removed during the forging process, and why it is necessary to choose the benefits of descaling equipment to remove the scale.
