Among the companies that confirmed for Metalurgia 2020 are the refractory material manufacturers, such as Refrateck and RHI Magnesita. Refractory solutions are essential for processes in foundries, steel mills, forging of metals, and other industries since they ensure the manipulation and containment of materials at the highest temperatures in safe conditions.
Technology in refractories
Refratek will take to the stand at Metalurgia the technology employed in the production and marketing of refractory products, such as concretes, ramming masses, mortars, cements, refractory paints, special refractory parts and insulating materials. The foundry stands out among the satisfied markets, regarded as one of the most demanding markets for this type of product. Besides this, it supplies solutions for thermoelectric, ceramic, juice, paper (boilers), glass, metal forging, steelwork, steel mill and petrochemical industries.
With representation offices in different Brazilian regions and qualified technical team to indicate the best products and application processes, Refratek meets in a personalized way and with agility each customer’s needs. The company further has an adequate logistics to satisfy the specifications and the delivery terms, and centers on the continuous improvement of the supplied materials and in the development of new products and adequate applications for each type of equipment.
Another company from the segment also confirmed for Metalurgia is RHI Magnesita, global leader of the refractory industry with head office in Austria and presence in all continents. The company has the largest number of units in the entire world and is concerned with supplying innovative and reliable products, and wide variety of solutions. It has a vertical structure, from mining up to production, with the intention of supplying complete service solutions. The refractory products of RHI Magnesita are used in all high temperature industrial processes, which ensures the existence of steel, cement, lime, non-ferrous metals, glass, energy, environment and chemical industries.
Refractories challenge the most hostile conditions in order to keep them solid and stable at temperatures that go way beyond 1,200°C, to contain materials safely while they are burned, melted, exploded, casted and molded. And to protect equipment, such as ovens, anti-thermal, mechanical and chemical stress, the work of RHI Magnesita is to provide responses to these extreme challenges, with the best solutions for the customers. For this, it makes available more than 120 thousand products, that vary from bricks and mixes, up to flow control mechanisms, such as gate valves, diverse valves and plugs. The useful life of these products vary from one day up to 10 years and the base materials used to manufacture them are magnesite and dolomite – which require a skillfull handling: the melting point of casted magnesia is higher than 2,800°C.
