There are many kinds of carburizers on the market. Carburizers are widely used in the market because they can be used as anode conductive materials in aluminum electrolytic cells. Many customers have a lot of doubts when choosing the carburant. They don’t know which is better and which is suitable for their own use. Here is a detailed introduction of how to choose the high-quality carburant.
For carburizer, the higher the treatment temperature is, the better the degree and effect of graphitization will be. Here we suggest to choose the carburizer of high temperature graphitization treatment, because a good carburizer has high absorption rate and fast dissolution speed, which is conducive to reducing energy consumption, effectively increasing the core of molten iron and improving the metallurgical quality; choose the carburizer with low impurity elements such as sulfur and nitrogen. In addition, the nitrogen content of carburizer with high sulfur content is also high. When the nitrogen content of gray iron is higher than the equilibrium concentration, it is easy to produce cracks like nitrogen pores, while that of nodular iron is easy to produce shrinkage defects in the thick wall, and when the impurity content is high, it increases the tendency of slag inclusion. According to different furnace sizes, we can choose a reasonable size of carburizer, which can effectively improve the absorption rate and absorption speed of high-speed liquid iron. In the final selection, it should be noted that the material quality of graphitized carburizer after high temperature treatment is relatively good. If it is not tested, it can be used for hand feeling, eye view, and good marks can be drawn on the paper.
