Unique quarry-to-furnace model

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.

CALDE® SHIELD forms an impervious layer during the sintering phase to keep steam from passing through. This prevents zinc damage to any acidic, neutral or basic DVM refractory materials, as well as increased robustness, reduced coil damage and improved hot face lining reliability when melting zinc-plated scrap.

Your Equipments

Holding Furnace

Holding Furnace

The holding furnace takes a key role in the modern foundry production environment. Containing large amounts of completely alloyed metal ready for transfer to casting stations, holding furnaces are typically the foundry's bottleneck requiring highly reliable refractory lining concepts that exhibit superior properties with respect to both corrosion resistance and thermal insulation. Calderys offers a wide product range for all sizes of holding furnaces for steel, iron, and non-ferrous alloys, including the lining of the commonly used channel inductor. Our main focus lies on the castable and dry vibrating technologies that both allow you to significantly reduce the energy needed per tonne of metal.

Pouring Furnace

Pouring Furnace

Pouring furnaces are found in various sizes and configurations, especially where automated moulding lines are used for large scale serial production. Calderys offers solutions for all sizes of pressurised and unpressurised pouring furnaces, including the lining of channel inductors or coreless inductors as well as completely coreless automated pouring furnaces. Our refractory materials are suitable for all alloys, including steel, iron, and non-ferrous alloys. Taking account for the ever increasing demand for sustainable production processes, we offer advanced insulating solutions for unheated pressurised pouring furnaces.
All Details
Ladles & Receivers

Ladles & Receivers

Calderys offers a variety of refractory solutions for all kind of ladles, receivers, and converters as well as unheated pouring units which usually are all exposed to extreme temperature changes as well as aggressive slag build-up. Versatile products reduce the amount of work needed to keep those vessels clean and ready for their job.
