Recognized nationally and internationally for excellence in solutions for the treatment of liquid metals, Tecnosulfur presents its technologies, with emphasis on the innovative MT (Multi-Treatment) line of cored wire. The encapsulated cored wire technology, known as cored wire, integrates in a single step, the operations of desulfurization, nodularization and pre-inoculation in cast iron.
This solution eliminates the need for multiple manual additions, reducing variability, rework, and process time. With this, foundries of different sizes can achieve greater standardization and productivity in their liquid metal treatment processes, in addition to operational safety and economic efficiency.
MT cored wire is a cored wire specially developed for applications in foundries that want to optimize the treatment of liquid metals. Its differential is in how it acts. Through automatic feeders, the wire is introduced in a controlled manner into the metal bath, ensuring precision in dosing and consistency in results.
By integrating three critical steps of liquid metal treatment into a single application, desulfurization, nodularization and pre-inoculation, the process eliminates waste and minimizes failures common in traditional methods. This results in better quality parts, with less variation in magnesium and sulfur and with more consistent metallurgical characteristics.
The MT line is seen as a paradigm shift, allowing companies that produce only gray cast iron to migrate to nodular iron, adding value to their portfolio and increasing competitiveness in the market. The automation of liquid metals treatment also ensures traceability, which is essential for foundries seeking international quality standards and process certifications.
LIQUID METALS TREATMENT WITH COMPETITIVE ADVANTAGE
The MT line presents itself as a strategic differential in the treatment of liquid metals by offering a reduction in process variability ensured by automated dosing, improved productivity with shorter treatment time and less rework, flexibility with the possibility of expanding the portfolio of alloys produced and operational safety by reducing the exposure of operators to chemical products.
This innovation, already used in the United States and Europe by Affival (a company of the Opta Group), now arrives in Latin America adapted to the needs of the regional industry, with Tecnosulfur leading its practical application in Brazil and neighboring countries.
With this technology, there is less generation of slag and solid waste, in addition to a reduction in the consumption of alloys and granular materials, eliminating excesses typical of manual processes. This means lower smoke and dust emissions, ensuring a cleaner and safer work environment for employees. Another positive impact is the possibility of environmental certifications, since foundries that adopt MT cored wire are able to prove sustainable practices in line with the requirements of the global market.
