Capital Refractories: Primary & Secondary Melting of Metals: Aluminium

Aluminium

Capital Refractories has developed a range of castables uniquely formulated to give exceptional service in various parts of aluminium furnaces: both melting and holding furnaces. Capital does not believe in a one size fits all approach, rather we put the right refractory in the right area. This improves operation performance in terms of both longevity and operating costs.
