Sulfurizing agent
Principle of sulfur addition agent (ferrous sulfide): Low sulfur content in gray cast iron molten iron is harmful: poor inoculation effect, poor graphite morphology, and poor cutting performance. The appropriate range is 0.07% -0.12%. In this range, sulfur shortens the length of graphite, dulls the ends, changes the shape, and improves mechanical properties. When the sulfur content is less than 0.05%, sulfur addition treatment must be carried out. According to metallographic analysis, sulfur in molten iron exists in a special form, so it is necessary to use professional manufacturers to produce sulfur addition agents when adding sulfur. Remember not to use sulfur addition products indiscriminately, as it may damage the inner wall of the furnace, produce unqualified products, and greatly increase costs. May cause an explosion. The special sulfur additive for cast gray iron produced by Hengkai Metallurgical Materials Sales Co., Ltd. in Luanchuan County is convenient, safe, and reliable to use. It produces very few impurities, has a high absorption rate, and a recovery rate of over 95%. During electric furnace production, a small amount of iron is added to the electric furnace, and a sulfur additive with a particle size of 8-25mm is added to the furnace according to the sulfur demand. Then, iron is added to press the sulfur additive up for melting. For ductile iron, low sulfur content (less than 0.008%) in the original molten iron is also unfavorable. The normal range of 0.010% -0.014% is better. However, for electric furnace melting, sulfur oxygen inoculants need to be used in this range for micro sulfur addition to improve the activity of molten iron
