The so-called
carburant is to effectively increase the carbon content in the molten steel after being added, so the fixed carbon content of the
carburant must not be too low, otherwise to achieve a certain carbon content, you need to add more factors in the carburant, which undoubtedly increases the amount of other unfavorable elements in the carburizer, so that the molten steel can not get a better income.
Low sulfur, nitrogen, and hydrogen elements are the key to preventing nitrogen holes in castings, so the lower the nitrogen content of the
carburant, the better. Other indicators of carburant, such as the lower the amount of moisture, ash, and volatile matter, the higher the fixed carbon content, so the higher the fixed carbon content, the content of these harmful ingredients must not be high.
According to different smelting methods, furnace types and sizes of smelting furnaces, it is also very important to choose the appropriate
carburant particles, which can effectively increase the rate of absorption of carburant by molten steel. The particle size of
carburant for the induction furnace is 0.2-5mm, others need to be judged and selected according to specific details.
