The recarburizer is high-carbon and low-sulfur, which can fully absorb without slagging, reduce the cost of spheroidization and slag removal, shorten the smelting cycle, save energy consumption, not only meet your requirements for carbon content, but also effectively control sulfur The amount of the element makes the carbon element in the casting most of the microscopic form appear as A-type graphite, obtaining fine and uniform graphite, promoting the spheroidization process, and effectively improving the production of iron graphite.
The many benefits of using recarburizers have made more and more manufacturers purchase them. When the amount of carbon is not enough to adjust the carbon content, the slag in the furnace is cleaned first, and then the recarburizer is added, heated by the molten iron, electromagnetic stirring or Manual stirring can dissolve and absorb the carbon, and the recovery rate can be about 90%. If the low-temperature recarburization process is adopted, that is, only a part of the charge is melted. When the molten iron temperature is low, all the recarburizers are added to the molten iron at one time. At the same time, it is pressed into the molten iron with a solid charge to prevent it from exposing the surface of the molten iron. This method can increase the carbon content of molten iron by more than 1.0%.
