PIG IRON MARKET OVERVIEW
The integrated plants are currently present where good-quality raw materials for reduction processes are increasingly scarce and expensive. This context is favorable to the use of ores and fuels with higher contents of contaminants. On the other hand, client requirements for steel quality are increasing, which results in difficulties in manufacturing some types of products, such as nodular and special iron, intended for casting or fine steel plants to supply the market of special pipe plates. But it is not about sulfur only. Phosphorus also causes problems at the Blast Furnace operation.
Tecnosulfur offers a full line of ladle-applied desulfurization, dephosphorization, and desiliconization agents used in the primary refining of pig iron. We customize the products for use in accordance with the requirements of each process. The agents consist of calcium oxide, calcium carbide, metallic magnesium, and others. Tecnosulfur also supplies the equipment required to apply these products, such as agent addition or injection systems. A specialized team makes the operation projects, assembly, start-up, and follow-up.
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, ensuring customer satisfaction.
The primary purpose of the Tecnosulfur line of desulfurization, dephosphorization, and desiliconization agents is to enable the manufacture of the finest pig iron. The products are applied using a deep injection in ladles using refractory spears and carrier gas. Our advantages include lower specific consumption, higher rates of desulfurization and dephosphorization, higher treatment speed, and lower cost per treated ton.
- Removal of sulfur and phosphorus at extremely low levels, which allows for the manufacture of fine steels and demanding applications
- Desulfurization and dephosphorization rates over 90 percent
- The pig iron gets treated with specific, cost-effective, low consumption of the agent, which allows for the use of lower-quality raw materials in the Blast Furnace
- Treatment time tailored to each process
