How do you choose a recarburizer


A black object with a high carbon content or a follow-up product of coke after passing through gray particles (or lumps), participating in the Chinese metal smelting furnace to improve the carbon content in the molten iron. On the one hand, we can effectively reduce the molten iron Oxygen content, another important aspect is to improve the performance of smelting metal materials or the mechanical system performance of castings.
There are many sources of carburizers and different shapes. The price varies greatly depending on the processing technology and composition. The traditional method is similar to the traditional condensing cupola, using iron, returning scrap steel, ferroalloys, etc. as the charge of the metal; the new synthetic cast iron consumption process: using scrap steel as the charge, and applying a carburizing agent to adjust the carbon equivalent of the molten iron. The latter social consumption lifestyle makes it easier to ensure high-quality iron liquids for enterprises, and at the same time, it can reduce the management cost by using less or replacing pig iron and using scrap steel. To put it plainly, we can refine the best castings with scrap materials using carburizers.
Foreign carbon-reinforcement technology companies have become increasingly mature, and this new process in China has only been launched from time to time in recent years. Many people in the industry have not fully understood the quality and quality of carburizers, and some founders can choose to use carbonizers. Some misunderstandings. For example, in order to mix the meaning of the fixed carbon content and the carbon content of the carbon reinforcement, the fixed carbon value is calculated based on the moisture, volatility, ash, and sulfur content of the sample, and the carbon content is directly obtained through a carbon meter. Some carburizers have high ash carbon content, but their fixed carbon value will not be ideal. Some casting technicians stop unilaterally judging whether they can provide high quality from the fixed carbon content of the carburizer and its material and cultural properties. As a result, it is likely to buy one-sided, which will cause the carburizer purchased by the enterprise to be worthless.
