Iron & steel applications

Concepts for electric arc furnaces.


Many well-known steel producers and foundries use Refratechnik Steel products when lining their modern electric arc furnaces.

In many years of practical application, the high-grade and super-grade MACARBON® types (mostly 100% high-purity fused magnesia products) have proved their worth and have helped to extend furnace service life and reduce maintenance. The result is a considerable reduction in costs. Top-quality tapping systems and high-performance refractory adhesives complete the product range.
