Magnesium is also used in the ductile iron production to promote the nodularization of graphite and also as an alloying element in the production of magnesium-based ferroalloys.
• Magnesium Alloys
Magnesium Alloys are used in a variety of foundries, mainly in diecasting production for automotive industry, tools, electronic equipment such as computers and mobile phones, when light weight is important.
• Magnesium for the desulfurization of pig iron.
In a powder form and mixed with other materials, Magnesium is commonly used as a desulfurizer in many metallurgical applications and offers the best performance and cost benefit in the following cases:
1 - Iron requiring low levels of Sulfur, below 0.010%
2 - Limited time for desulfurization in steel making
3 - Heats with low temperatures.
4 - Heats with high initial levels of Sulfur
The most common desulfurizing mixture is pulverized lime and Magnesium powder (below 1 mm in size). The Magnesium content in the mixture varies from 5% to 20% depending on the type of injection equipment and the available time for desulfurization
• Desulfurization Equipment
Rima manufactures and supplies sophisticated injection and co-injection equipment for desulfurization of pig iron. The company maintains a specialized group of trained technicians and engineers that provide the best available technical support and assistance.
