SUE SUA SUB chamotte bricks were developed by us to provide a chamotte product with increased resistance to sudden changes in working temperature, known as thermal shocks. They are especially suitable for use in furnace cars.

Product lines A65, A70
These include typical mullite refractory products based on fused mullite. They are manufactured from pure raw materials, which results in low porosity of the products.

When designing refractory casting paths, flexibility and the ability to adapt the shape and size to the working conditions, specific technological equipment, and procedures play a key role. Thanks to our versatile molding department, we can handle both large-scale production in the thousands and small series, including a few pieces of complex ceramic shapes.

We participate in the design and manufacture of all necessary molds. We prepare a detailed production drawing for each shape. Over more than 135 years of operation, our specialists have developed documentation and a database of parts that allows us to produce more than 5,000 shapes on demand without the need to manufacture new molds.
