Capital Refractories is one of the largest independent refractory
companies in the UK. Capital Refractories has been manufacturing, supplying and installing high quality refractory products
to metal melters for almost 50 years. Today, Capital Refractories' services to the metallurgical and thermal process
industries operate on a global scale, with clients in over 40 countries worldwide.
Induction furnace linings
Refractories specialises in supplying refractory linings and associated products to metal melting, foundry and cement industries around the world. Capital Refractories manufactures a wide range of dry vibration rammable
products for lining coreless induction furnaces, vacuum coreless induction furnaces and channel induction furnaces for the
melting of steel and high temperature alloys, iron, copper, bronze, aluminium and masteralloys. These dry vibration induction
furnace linings include refractories based on alumina-magnesia spinel-forming systems, fused and dead-burnt magnesia-based
systems, alumina and alumino-silicate-based formulations. The dry vibration induction furnace rammables are supplemented by
a wide range of topping, ramming and patching refractories and other refractory products.
also has an extensive range of castables, which can be supplied pre-cast and fired, for the metal melting, cement and other heat-processing
industries. The castables range include dense, insulating and gunnable medium cement castables, low cement castables and free-flow
(self-flow) castables. Capital Refractories also has a comprehensive range of non-wetting, aluminophobic and insulation castables
specifically designed for primary and secondary melting of aluminium.
Capital Refractories, from its state of the art factory in the Czech Republic, produces a wide range
of specialist shaped ceramics including iso-pressed crucibles and vibro-cast crucibles in alumina, chrome-alumina, magnesia,
mullite, zircon and zirconia. Capital Refractories also produces slip-cast one-shot liners based on silica or alumina for
investment foundries. The product range is further supplemented by a range of specialist shapes for a range of applcations
such slide gate inserts, ceramic core setters.
Gas diffusers and bottom pour ladle
Capital Refractories provides a range of products to improve cast quality such
as the Unibore/Multicast stopper and nozzle bottom pour system for ladles and auto pour which improves metal flow and quality
as well as offering a quick change nozzle for improved cleanliness or to easily change nozzle diameters. Another product to
improve metal quality is Capital Refractories' gas-permeable diffuser (also known as a porous or purge plug) which can significantly
improve the quality of both ferrous and non-ferrous metal in melting furnaces and ladles.
