How to control the scale problem of precision forgings in hot die forging?

The oxide scale on hot forgings seriously affects the accuracy and appearance of forgings. The control methods mainly include: heating with controllable atmosphere, strictly controlling the heating temperature, selecting warm upsetting process and heating isolation film technology (such as heating coating). In addition, the method of removing oxide scale after heating from the electric induction furnace can also be adopted.

The production quantity of oxide scale depends on the steel grade, induction furnace type and heating atmosphere. Forging stock has a great influence on oxide scale. Therefore, the heating time cannot be extended arbitrarily, and the heating equipment and heating mode should be actively improved. The method of roughening the blank once can be used to remove the oxide scale on the press or hammer; Then, after each blow twice, take out the forging and blow off the oxide scale. This helps to reduce the influence of oxide scale on die forging blank. In addition, hydraulic scale removal, scraping, wire brushing and the use of blank making and pre forging groove to break the scale can reduce the wear of the die.

At present, China's forging industry has taken the descaling process as standard in the forging production line. The descaling cleaning machine has been widely used in the Chinese market for 8 years and has received good feedback.

Transmission Drive Shaft Descaling Device

The descaling machine from Descaling technology, the main body of the equipment is composed of a pressure system, a transmission system and a filtration system. The three systems jointly use the principle of high-pressure water descaling to complete the cleaning process of the forging scale.

Drive Shaft Bolts Surface Treatment

The high-pressure water descaling system is adopted, and the high-pressure water generated by the high-pressure water pump enters the descaling nozzle and is sprayed on the surface of the forging (or intermediate billet). The oxide scale has undergone the process of being cut, rapidly cooled and contracted, peeled from the base material, and washed away from the surface of the forging, thereby removing the oxide scale.

The descaling machine is equipped with two water tanks. The water tank has a built-in filter screen and a net basket to form the filter system of the equipment to prevent oxide scale from entering the water pump and affect the service life of the equipment. At the same time, it is equipped with a magnetic shovel to clean the oxide scale in the water tank.

The frequency conversion motor and the chain constitute the transmission system, which is responsible for transporting the forgings for the cleaning process. The transmission speed of the chain can be adjusted to ensure that the temperature of the forgings after cleaning is small, which is conducive to subsequent forging.

1. What kind of forging pieces is descaling machine suitable for?

The descaling machine is applicable to the forging production line. It can clean the oxide scale generated after heating by induction furnace and effectively improve the surface quality of products.
2. How to choose the model of descaling machine? Can it be customized?
You can select the corresponding standard model through the diameter of the round bar and the size of the billet after making. For details, please check the parameter navigation bar of the webpage. If there is a need for customization, we can also provide customized services according to the customer's raw material size and process.
3. How to daily maintain descaling equipment?
We will recommend that customers regularly clean the oxide scale in the water tank. You only need to use a magnetic shovel to remove most of the oxide scale. But also regularly replace the water in the water tank to ensure a normal filtration cycle.
4. Does the principle of high-pressure water descaling change the metallographic structure?
This method has been tested by a third-party organization. The test report shows that there is no change in the metallographic structure before and after cleaning, which has no effect on the later process.
5. How effective is the descaling machine? Is there a reference video for descaling equipment?
Descaling Technology has served more than a thousand forging factories in China, and received a large number of market feedback results. Regarding the on-site use of the equipment, please click into official YouTube account as below for more information.
