Due to the complex design of the shaft furnaces, special products which are safe and simple to process must be used. Refratechnik uses high abrasion-resistant castables here, as well as slag- and corundum-resistant castables for the smelting and holding.

The close collaboration with furnace manufacturers and plant operators ensures that Refratechnik castables consistently meet high requirements and boast optimum processing properties at all times.
