Capital 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. Capital Refractories also supply magnesia and magnesia-chrome bricks for furnace linings. The dry vibration induction furnace rammables are supplemented by a wide range of topping, ramming and patching refractories and other refractory products.

In 2009 the Penn Refractories castable range was incorporated into the Capital portfolio of products. This combined product range and over 25 years castable knowledge has enabled Capital to offer a more comprehensive range of superior refractories that are specifically designed for use in most heat application industries.

With the addition of the Penn Refractories product range Capital has not only expanded its considerable product base it has enabled them to provide the already approved Penn castables and gun mixes into arduous industries such as petrochemical and combustion industries.

The extensive product range includes medium and low cement products for specific applications and industries. A range of phosphate bonded castables is also available. We can also offer precast shapes in a wide variety of materials, manufactured in our specialised casting facility, mouldables, rammables, refractory jointing cements and basic tundish maintenance materials.
All products are manufactured in accordance to the ISO 9001:2008 quality management system.
