Start Your Career with FIRE

The three biggest foundries in Sweden – Volvo, Skania, and SKF – have implemented a new, three-part refractory solution for coreless induction furnaces. Now available in North America, the new CALDE GUARD solution from HWI comprises (1) a boron-free silica-based lining that is paired with (2) a precast top ring as well as (3) specialized installation, service, and aftercare. The result is 25% longer lining life than all other refractory concepts. Read the full article in Modern Casting.
