Iron sulfide 60#

Special copper smelting sulfur increasing agent generally refer to sulfur enhancing products used to increase the sulfur content of gray cast iron or molten iron. Low sulfur content in gray cast iron molten iron is harmful: poor inoculation effect, poor graphite morphology, and poor cutting performance. 0.07% -0.12%. In this range, sulfur shortens the length of graphite, dulls its ends, and bends its shape, improving its mechanical properties. When the sulfur content is less than 0.05%, sulfur addition treatment must be carried out. Metallographic analysis shows that sulfur in molten iron exists in a special form, so special sulfur adding agents must be used when adding sulfur. Do not use sulfur or other sulfur-containing minerals, as it will greatly damage the internal structure of the casting! When producing an electric furnace, a small amount of iron is added to the furnace, and a sulfur increasing agent 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 increasing agent onto the furnace for melting. The absorption rate is above 99%.Efficient sulfur increasing agent.It is one of the Casting Specific Sulfurizing Agent.
