Demanding Cowper designs lead to higher temperatures in the area of the hot blast stove, especially in the dome area. This increases the demands on the quality of the refractory lining and the extremely stressed grate bricks.

The solution: our Suprath and Silrath grades, as well as pre0fired concrete molded parts.
They ensure very good heat storage, good resistance to alkalis and abrasion, and a smaller change in length.

Our refractory bricks - in Porrath grades - in a wide variety of formats round out the product portfolio.
Long-term partners confirm that RATH products last up to 20 years in ideal cases.
