Calderys launches CALDE GUARD: a state-of-the-art solution designed to improve the service life and efficiency of foundry furnaces

CALDE GUARD is a comprehensive concept comprising a combination of products – a lining based on a boron-free, quartzite dry ramming mix and a prefabricated top ring – as well as their manufacture, installation, maintenance and after-sales support. Whilst the boron-free SILICA MIX lining supports healthier manufacturing processes, the prefabricated ring is designed for the upper section of induction crucible furnaces to reduce mechanical abrasion.

Calderys supplies and installs the lining and the prefabricated upper ring at its own foundry service centre. This approach is designed to extend the service life of furnaces, whilst reducing downtime and increasing plant availability. Full control over this process ensures that Calderys can supply high-quality products for every delivery and all areas of the furnace lining.

In addition to ensuring optimum product quality by manufacturing the furnace rings in-house, Calderys offers comprehensive on-site support at the customer’s premises to achieve the best possible results.

Håkan Andersson, Calderys EMEA Sales Manager, says: “CALDE GUARD was born out of environmental concerns and has ultimately developed into a comprehensive solution that improves the service life of furnaces across all sectors. Calderys is unique in this respect, as it is able to provide a complete proof of concept covering the materials, their installation and their maintenance. Furthermore, as we know that every customer is different, we offer the necessary customisation, installation and training to ensure that everyone has the right knowledge of CALDE GUARD and can fully exploit its potential.”

Aurélien Cadars, Senior Vice-President EMEA at Calderys, adds:

“Calderys is proud to introduce CALDE GUARD as a premium solution for our customers. Although a higher initial investment is required, foundry operators can expect a significant return on investment within a short period of time. As a trusted partner to the industry, Calderys remains committed to supporting customers in their pursuit of greater sustainability.

By reducing downtime during installation, increasing the number of melts per lining and enhancing plant availability, CALDE GUARD enables customers not only to improve their efficiency in terms of environmental sustainability, but also to achieve greater cost and operational efficiency.”
