Calderys will provide you with tailored recommendations on all options for transport ladle linings, including hot face coating, cold repairs, as well as in-house relinings (deliver your ladle to Calderys for the relining — highest installation efficiency), and even on-the-road ladle solutions for aluminium transport with ultra-low thermal loss. Just contact our refractory experts for our advice and for a dedicated brochure on the Aluminium transport ladle.

The Coreless Induction Furnace, commonly known as CIF, is an effective furnace type for remelting clean scrap and processing difficult aluminium alloys (such as lithium containing alloys) as well as master alloys. Top performing refractory solutions for this equipment need to strike a balance between the speed of relining and refractory performance.

Multiple refractory installation techniques are possible: the best-known are DVM (dry vibrating mix), wet ramming mass, and precast crucible. Calderys can supply full solutions (products and services) for all CIF areas including coil grout, spout, rings, cover, and any patching repairs.

Please contact our refractory experts to request a specific brochure on Aluminium CIF.

The channel inductor furnace for secondary aluminium provides an efficient way of recycling / remelting clean scrap. Calderys monolithic refractory ensures a long lifetime in the vat with excellent resistance to corrosion from aggressive alloys, while also providing good thermal insulation. Calderys experts are also focused on providing you with high mechanical strength in the bottom for resistance against falling scrap when loading the charge.

A particularly sensitive area of this furnace are the channel inductors as well as the inductor joint with the vat, so Calderys supplies a wide range of different monolithic solutions for the inductor: standard DVM (dry vibrating mix), wet ramming mass, cast, and precast solutions. There is also an "in-house service" possible with refurbishment of whole inductor at one of our Calderys sites, delivered ready to use to your plant for maximum efficiency.
