Kiln furnitures produced by Estiva Refratários, besides the intrinsic qualities of cordierite and cordierite-mullite, presents an excellent dimensional stability, very good thermal shock performance and high resistance to hot deformation in conventional and fast firing cycles. Operating temperatures can reach up to 1350 ° C, with high performance and creep

Estiva Refratários low mass car kiln perimeter blocks can be used in tunnel and shuttle kilns, operating at temperatures up to 1350 ° C. The concept of using air as a thermal insulation is widely used in the production of the cast and/or drained parts, bringing to the product excellent

Generally, the production of structural ceramics is very aggressive towards the refractories, considering the type of fuel, atmosphere of the furnace, heavy load on the parts, high soaking times and firing cycles. To solve a large part of these problems, Estiva is a partner of Resco/Paco (USA) for supplying of

Main refractory product used in the production of ceramic articles, Estiva batts are manufactured in cordierite and cordierite-mullite through the extrusion, slip casting and pressing processes. Regardless of how they are made, our batts have excellent dimensional stability, high flexural strength under normal and application temperature, and excellent thermal shock

Besides batts, columns, firing supports, lavi rings and other refractory products produced by Estiva, there is also the possibility of manufacturing taylor made parts for different purposes, with direct alignment between customer need, product properties and exclusive designs. As an example of some special parts, we can highlight: pins, burner

Estiva Refratários is Latin America leader in the manufacture of ceramic rollers and has an updated technology and strict process control to guarantee the best quality to the rollers. The use of Estiva refractory rollers guarantees optimum performance for ceramic kilns, resulting in higher productivity, reduction in maintenance costs, shutdowns

In addition to the great ease of assembly, Estiva Refratários suspended roof systems and kiln linings have a lighter weight per area and, combined with insulating fibers, result in a significant reduction in fuel consumption. Its use in intermittent furnaces as a protection element of the ceramic fibers is also

Designed to meet the process characteristics of each of our customers, Estiva saggars and trays are manufactured through slip casting and with variations in formulation to support the process specifications. The design can be from a simple box to more complex formats on demand. Related Markets Pigments and Coloring Suppliers

Refractories based on silicon carbide (SiC) are widely used in ceramic applications due to high refractoriness, excellent mechanical strength, high thermal conductivity and good resistance to thermal shock. As result of these characteristics, the use of this type of material, besides the inherent durability of the products, has as main
