Litai Technology information: Why still will there be oxidation after using the descaling machine? The forges that have used our descaling machine do not need me to explain this problem anymore, because they all know the reason. Today, I will explain the forges that do not know the reason, so as to dispel their doubts.
Descaling machine used before forging, placed between the electric furnace and the press, the purpose of removing the oxide before the forging is to not let the oxide remain on the surface of the forging, and then there will be no oxide to be brought into the interior of the workpiece, so as to improve the quality of the product.
There is a feedback from the forging factory that it is removed before forging, but after forging out, the surface of the forging still has a layer of oxide! It is said that we are not clean, here to explain to you, because hot forging products, after forging the temperature will not suddenly drop to a very low, so there will be secondary oxidation is very normal, but the secondary oxidation skin is very thin, it is not as hard as the newly heated oxide skin, which is why we recommend that you put the oxidation machine before forging. Not after the workout. If it is removed after forging, the early oxide has been brought to the inside of the forging, which has affected the quality of the forging.
I believe you all understand why we put the descaling machine before forging instead of after? If you have any questions, please contact me!
