DMK is made of high purity magnesite and high quality chrome ore which are shaped at high pressure and burnt at high-temperature furnaces.
The bricks have good high temperature performance and strong resistance for metallurgical slag erosion.It has been widely used in the main areas of industrial furnaces for ferrous and non ferrous metallurgy.
