Refractories have been produced at the Friden site since the 1890's. The company has a wealth of experience in refractories technology and the manufacture of refractory products that is almost unrivalled in the UK.
DSF are specialist manufacturers or alumino-silicate refractories, and have a complete range of dense products from 40% to 99% alumina and specialist materials such as magnesia - alumina spinel and zircon manufactured in standard or special shapes.
We also have a complete range of monolithic material including mortars, ramming mixes and conventional and low cement castables.
Blocks are pressed or cast to shape, depending on size and complexity and after forming the products are fired in our intermittent kilns to the ideal temperature to generate the optimum properties. We have the capability to fire up to 1700°C.
DSF have extensive cutting and grinding equipment to accurately machine blocks to create precise assemblies with tight joints, with layout facilities where the blocks can be pre-assembled and inspected.
