Forging die refers to a tool that can form blanks into die forgings. Forging die is the key process equipment necessary in the production of die forgings, and it is a tool that needs to be used in every stroke of the equipment. It plays a pivotal role in the production of die forgings. Die wear is common during the forging process. Die wear mainly refers to the relative movement between the two parts in the friction pair. In addition to observing the general laws of the wear of mechanical parts, the wear of the forging die also has its particularity due to its harsh working environment. After the forgings are heated by the heating furnace, they need to be forged with a press, because the hardness of some of the oxide scales is relatively high and the distribution is uneven. At this time, the harder oxide scale will accelerate the wear of the mold, which virtually increases the cost of the enterprise. However, customizing a mold is relatively expensive, not to mention that it is common for the mold to be worn during the forging process. Therefore, many forging plants have been using various methods to remove the oxide scale on the surface of the forging to reduce mold wear. At present, the most commonly used method of forging oxide scale treatment is to use the principle of high-pressure water descaling to remove, and it is also the most feasible method for oxide scale removal at present. The oxide scale can be treated by the high-pressure water generated by the high-pressure pump. The oxide scale cleaning process is very fast, the temperature is very little, and the cleaning is very clean, so that the oxide scale is reduced during the forging process, and the damage caused by the excessively hard oxide scale is avoided. Unnecessary wear of the mold reduces the service life, which increases the service life of the mold and at the same time improves work efficiency. Therefore, the use of a forged oxide scale cleaning machine can not only improve the surface quality of forgings, but also increase production efficiency. And it can greatly reduce the mold wear caused by oxide scale, so the use of forging oxide scale cleaning machine to remove oxide scale before forging is a process worthy of promotion and publicity.

During the heating process of the forging, as the induction heating furnace is processed, the surface of the forging will produce oxide scale. If the oxide scale is not removed in time, it will enter the forging process along with the forging, causing pits on the surface of the forging and uneven forging defects. This is the main reason for the uneven surface of the forging, and some of the oxide scale will be brought into the mold and damage the abrasive tool. Therefore, it is necessary to remove the oxide scale. Forging factories have always been troubled by the problem of oxide scale on forged parts. The earliest way to remove the oxide scale was to brush it off with a wire brush. Later, a peeling machine appeared, followed by a high-pressure water gun flushing, some forging manufacturers do not have high requirements for forgings, and directly use upsetting to remove the oxide scale. However, some of the deficiencies are that some oxide scales cannot be cleaned up and are brought into the forgings, which affects the surface quality of the forgings, and they gradually appear later. Various methods have been adopted, but the problem of oxide scale cannot be removed. In recent years, more and more new energy vehicles are manufactured, and the demand for auto parts has also increased, such as automobile connecting rods, crankshafts, gears and other forgings. The surface quality of many automotive precision forgings is not very good during the forging process, but at the same time The surface quality requirements of forgings are high, and major forging manufacturers are looking for ways to change the surface quality of forgings. In response to the above market demand, Nanjing Descaling Technology has developed a forging scale cleaning machine. After customers who are forging auto parts learned about our equipment, they contacted Nanjing Descaling Technology about the descaling machine and sent for forging tests. The results are still very satisfactory, and they are very satisfied with the extremely small temperature drop after descaling of the forgings. In addition, the scale cleaning machine chooses appropriate nozzles and arranges them reasonably. At the same time, the system pressure fluctuation is very small, which greatly improves the removal rate of the electric furnace oxide scale. After the oxide scale on the surface of the billet is removed, the surface is smooth and the quality of the product is greatly improved. This not only makes the appearance of the product beautiful, but also greatly improves the competitiveness of the product in the market. If you are still troubled by the oxide scale, then contact us soon. For more details, please refer to our YouTube video or contact us.

Manufacturers know that the oxide scale produced by induction furnace heating is very stubborn to adhere to the surface of the workpiece. If it is not processed before forging, it will have a great impact on the quality of the product and waste raw materials. Before the billet enters the forging process, through the high-pressure water descaling process, 99% of the phosphorous skin on the surface of the billet will be removed, which greatly improves the surface quality of the forging and the quality of the forging product, and can reduce the workload of subsequent machining. The machined surface requires a certain degree of dimensional accuracy, and the excess unevenness must be removed. Because the forging production line is equipped with a high-pressure water descaling system, it reduces the machining allowance for subsequent machining and improves the production efficiency of the factory. The potential cost of this part can not be ignored, including the loss of man-hours and materials. Let's analyze in detail through two customer use cases. 1. Removal of scale on automotive gear parts The customer requirements for the production of automotive gear forgings are very high. We have such a customer who produces gears. Before using the descaling machine from Descaling Technology, the net weight of a single blank gear blanking is 1.83kg, and the round bar blanking The required weight is 1.90kg. After using our Descaling machine, the blanking weight of the round bar has been saved to 1.85kg, which is equivalent to saving 0.05kg of raw materials for a product, a single raw material Although the weight is small, if it is mass production of 100 million pieces, we can save 500kg of raw materials. If a gear processing factory needs to produce gears for a long time, it may be 100,000 pieces, 1 million pieces or more, saving What comes down is a very substantial cost of raw materials. 2. Forging connecting rod production line can reduce the energy consumption of forging billet heating The application of the high-pressure water descaling system can help the forging connecting rod production line save more than 530 tons of raw materials every year, which is equivalent to the total amount of raw materials for this production line for 5 days. The power consumption for 5 days is about: 7000KW/HX20H/day X 5 days=700,000 KWH, the application of the high-pressure water descaling system can save about 700,000 KWH of electric energy each year. If the entire factory is calculated based on 5 production lines, 3.5 million billets will be heated to save energy. It can be seen that in the era of rising raw material and labor costs, the descaling machine from Nanjing Descaling Technology not only brings you a forging equipment, but also provides the forging industry with the gospel of the long-term development of the company!
