Your Equipments

Twin Chamber Furnace

The twin chamber furnace is a double-chamber furnace used to melt solid aluminum. It’s a key equipment for aluminum regeneration.

All Details

Dosing Furnace

Dosing furnaces are used to dispense an accurate amount of molten metal into the die casting machine. The process requirements of these furnaces require high quality refractories.

All Details

Tilting Rotary Furnace

The tilting rotary furnace is used for melting aluminum scrap of all types, such as dirty scrap, borings, etc.

All Details

Runners & Treatment Box

Runners are connected channels that convey the molten metal to different parts of the mold. Calderys provide various refractory solutions for this critical equipment in the aluminum production process.

All Details

Transport Ladle

The aluminum transport ladle's primary focus is to safely transport the molten metal around in a foundry. This ladle is critical for the rest of the process and require a good understanding of the foundry' processes.

All Details

Coreless Induction Furnace

The coreless induction furnace (CIF) is an effective furnace type for remelting clean scrap and processing difficult aluminum alloys and master alloys.

All Details

Secondary Holding Furnace

The secondary holding furnace is used for continuous and batch-type pyro-metallurgical processes in non-ferrous metals, such as aluminum, production lines.

All Details

Top Charging Furnace

The top charging furnace, also called as top loading or round melting furnace is a furnace which is loaded with scrap from the top of the furnace.

All Details

Sidewell Melter

Sidewell melters are advanced melting & alloying reverberatory melting furnaces. They are named sidewell because they are charged through the sidewell parts of the furnace, rather than from the top.

All Details

Channel Inductor Furnace

The channel inductor furnace for secondary aluminum provides an efficient way of recycling or remelting clean aluminum scrap.

All Details

Reverberatory Melting Furnace

The reverberatory melting furnace is used for smelting or refining aluminum. In this particular furnace, the fuel is not in direct contact with the ore but heats it by a flame blown over it from another chamber.

All Details

Casthouse Holding Furnace

The casthouse holding furnace keeps the molten metal at the right temperature, and homogeneity before the aluminum travels further to the casting operations.

All Details

Anode Baking Furnace

The anode baking furnace bakes anodes to produce carbon which is then used in the production of aluminum.

All Details

Potcells With Metal Transfer Ladle

Potcells are crucial in the process of primary aluminum making. Calderys has the refractory experience necessary for this equipment.
