IRON FOUNDRY OVERVIEW

With the increasing demand of the automotive and machine industry, foundries have been serving a highly demanding market concerning the mechanical properties of cast iron. Stronger and harder products are required to extend the life of components.

TECNOSULFUR SOLUTION

To serve the primary cast iron refining process, Tecnosulfur offers a complete line of desulfurization agents for application in the melting processes performed in cupola furnaces. They are manufactured on a customized basis to operate per the requirements of each step. The products consist of calcium oxide, calcium carbide, calcium fluoride, and others.

In addition to its recognized quality, Tecnosulfur provides its clients with enhanced products that comprehend a precise technical diagnosis, follow-up of the application by specialized technicians, and after-sale services that ensure customer satisfaction.

TECNOSULFUR ADVANTAGES

The primary purpose of the Tecnosulfur line of desulfurization agents is to remove sulfur from metal, resulting in fine steel. Applied through the Gasal system, they consist of the desulfurization agent in coinciding streams of metal/slags in a siphon ladle with stirring by inert gas. Advantages include lower specific consumption, high rates of desulfurization, high treatment speed, and low cost per treated ton.

OUTCOMES

• Removal of sulfur at low levels allowing for the manufacture of finer irons
• Desulfurization rates over 90 percent
• The cast iron is treated with a low specific consumption of agents, ensuring more cost-effectiveness that enables the use of lower-quality raw materials in the Cupola Furnace
• Tailor-made treatment time for each process

STEEL FOUNDRY OVERVIEW

With the increasing demand of the automotive and machine industry, foundries have been serving a highly demanding market concerning the mechanical properties of cast iron. Stronger and harder products are required to extend the life of components.

TECNOSULFUR SOLUTION

To serve the primary cast steel refining process, Tecnosulfur offers a complete line of customized sintered synthetic slags, with specific performance in each process. Such products consist of calcium aluminates, calcium and magnesium silicates, pseudo silicates and aluminates, and others.

In addition to its recognized quality, Tecnosulfur provides its clients with enhanced products that comprehend a precise technical diagnosis, follow-up of the application by specialized technicians, and after-sale services that ensure customer satisfaction.

TECNOSULFUR ADVANTAGES

The primary purpose of the Tecnosulfur line of sintered synthetic slags is to remove undesired elements in the steel (S, P, nonmetallic inclusions) and prevent hydrogen pick-up. They are used in electric furnaces or ladles with excellent spreadability while performing other important functions in the secondary refining of steel, such as:

• Protecting the hot metal by avoiding its contact with the atmosphere and, consequently, minimizing thermal losses
• Preventing the exposure of the electrode electric arc during the heating and melting in the EAF (Electric Arc Furnace) and reducing the wear of the refractory lining and the vault
• Reducing the tap to tap and consequently the consumption of electricity
• Forming a coating in the ladle that extends the service life of the refractory linings
• Reducing the flicker effect due to higher stability of the electric arc and improve the process operating conditions

OUTCOMES

• Deep removal of nonmetallic inclusions that allows for the manufacture of special steels
• Significant increase in the service life of ladles
• Reduction in the consumption of electrodes
• Reduction in the consumption of electricity
• Better control of basicity
• Tailor-made treatment time for each process
