Refractories for the Steel Industry

Steel

DSF produce a range of high alumina bricks, both fired and chemically bonded for use in iron and steel ladles, arc furnace roofs, reheat furnaces, coke ovens and tundish nozzle blocks. We also have a complete range of Monolithic Refractories for the Steel Industry including castables, gunning mixes, ramming mixes and mortars, and the ceramic anchors to fix them.
Semi-universal Ladle Bricks



Pre-cast Bottom Blocks being installed 		Ladles - Iron, Steel and Ferroalloys

DSF specialise in ladle refractories, producing bricks in ISO, DIN and other standard shapes including side arch, radial, mini key and semi-universal sizes.

Products in regular use are fired and chemically bonded bauxite bricks with chrome or pure alumina enrichment.

In each case products are carefully graded and heat treated to give optimum strength, porosity and pore size distribution values.

Ladle bottoms can be produced in bricks, or in the form of precast blocks based on bauxite or tabular alumina-spinel. A complementary range of free-flow castables are available to provide a complete ladle bottom construction.


Tundish - Continuous Casting

DSF also specialise in the production of tundish nozzle seating blocks, to tight dimensional tolerances in machine pressed chemically bonded 80% alumina, we also produce the mortar to mount the SEN and ramming material to go around the nozzle block.
Tundish Nozzle Seating Blocks



Arc Furnace Roof in full operation 		Electric Arc Furnace Roofs

Complete roofs or delta sections can be produced in brick or monolithic form. We produce a full range of double taper bricks, normally supplied in phosphate bonded high alumina for tight construction and long life. Low cement castables are available for cast centres or precast delta sections

DSF is a world renowned supplier to the Glass industry, having extensive references with internationally recognised glassmakers for our products giving long campaigns in the float glass, container glass, fibre glass and other speciality glass industries.


DSF have a long history of supply of high alumina products for the steel and aluminium industries. DSF products are used in electric melting furnaces, steel and iron ladles and tundishes.

We also supply direct reduction kilns, aluminium holding furnaces, coke ovens and carbon bake furnaces.
High fired pure alumina and pure magnesia-alumina spinel materials are both used in carbon black reactors.

These are able to withstand the reducing conditions, thermal shock and very high temperatures associated with the process. They can be supplied in standard brick or complex shapes.

DSF products made to tight dimensional tolerances give excellent performance in rotary cement and lime kilns and preheaters, shaft lime kilns and multihearth calcination furnaces.

We also have products for other rotary kilns producing petroleum coke, activated carbon and calcining minerals.
Products are supplied to a wide variety of heat containment applications including incineration, Sulphur recovery, kiln construction and deck tiles, petrochemical burner blocks, hydrogen atmospheres, multihearth furnaces and many more.


A new company has been formed in China; DSF Refractories (Tianjin) Ltd, A wholly owned subsidiary of the UK company.

Production of refractories has now commenced, for supply to the local Chinese market and for export.
