Capital Refractories Ltd is one of the leading UK manufacturers of dry vibratable induction furnace steel melting linings used in the modern foundry and steel mini-mills for over 50 years. The spinel forming linings marketed under the “Coral” brand have been specifically developed for use in “typical” and arduous melting environments of the steel making process in induction melting foundries.
We complement this with a full range of ancillary products, including topping, repair/ patching materials, castables for ferrous and non-ferrous applications & installation equipment.
Capital Refractories pioneered the use of the permeable gas diffuser for use in the coreless induction furnace; this allows Argon to be purged directly from the base of the furnace into the molten metal prior to casting. Benefits include reduction of inclusions, gas holes & improvements in refractory life.
Products are manufactured in the UK, USA, China, Taiwan, Indonesia, India and the Czech Republic, details of all distributors, sales offices and product range can be viewed at www.capital-refractories.com
