NSF Partner Calderys

Calderys is a one-stop shop for all aspects of metal processing for ferrous and non-ferrous foundries, from melting, treating and transferring to the casting process. 


Our people have gained a wealth of knowledge and experience through working on local and international projects. We offer unique engineering expertise as well as state-of-the-art products, project management, and customized installation services. We have developed successful partnerships with hundreds of Foundry clients around the world and work closely with them to deliver high-performance, reliable, bespoke solutions. 


We supply refractory solutions for coreless induction furnaces (CIF), cupolas, ladles, receivers, converters, and holding and casting furnaces, as well as special bricks and insulating materials.

Our range of silica-based refractories produced from our own Swedish quartzite is made from the highest grade of raw material in the world.

Its excellent thermal stability and chemical resistance make it the perfect lining for DVM (dry vibrating mix) and inductors. The Spinel-forming DVM product line is a longstanding industry benchmark for steel CIF and uses raw materials with high refractoriness and all-round corrosion resistance.

This unique quarry-to-furnace model ensures high reliability and quality. Calderys also benefits from dependable, consistent access to other essential raw materials for foundry refractories.
