Kanthal® electrical ladle heaters
Controlled heating for increased productivity

By heating ladles with electricity instead of gas, aluminum producers as well as aluminum and steel foundries
can benefit from lower energy costs and increased
process control.

In Kanthal electrical heaters, the heating elements are
arranged in a reflector. This allows the radiation to
be more accurately directed towards the target area.

Kanthal ladle heater installations offer energy efficient
solutions for heating and pre-heating up to ladle temperatures of 1500°C (2732°F) and ladle sizes from ID
500 mm to ID 2100 mm (19.69 – 82.68 inches).
Kanthal electrical ladle heaters are supplied as complete
installations, comprising heating elements in a reflector casing, control and regulation equipment, commissioning and technical service. The innovative heater
monitoring and control system optimizes performance
and prolongs the lifetime of the heater by eliminating
overheating. The system ensures maximum and consistent power, which reduces process times.

Kanthal electrical ladle heater
advantages

More energy efficient. Net efficiency is 70%,

compared to only 20% for gas.

Multi-purpose. Innovative design enables the same

heater to be used for both heating and holding

Reduced process times

Increased refractory lifetime

Reduced CO2 emissions

• Cleaner working environment
• Complete installation

Optionally, certain models can have the heater automatically raised and lowered hydraulically, and there are
attachments on both sides to minimize heat loss from
the spouts. This goes together with a timer system that
starts preheating automatically at a preset time. Heating
is monitored and controlled by PLC.

Control equipment

Installation and commissioning

Kanthal electrical ladle heaters are delivered together
with control equipment specially designed by Kanthal
to ensure optimal heater operation. We deliver EN/UL/
CSA certified equipment according to your national/
company standards.

Kanthal electrical ladle heaters are supplied as complete
installations, comprising heating elements in a reflector
casing, and control and regulation equipment. Commissioning and technical support are provided on site by
Sandvik heating experts.

This innovative control and regulation system optimizes
performance and eliminates over-heating in order
to prolong the lifetime of the heater. It also ensures
maximum and consistent power. More power reduces
process times and reductions in time mean cost savings.

Technical service

Once the system is installed, we will support you with
preventive maintenance, repairs, replacements, service
and refurbishment. We offer service agreements and
technical team efforts on a global scale in order to keep
your ladle heaters productive for a long time.
Accessories

The Kanthal program includes the following
accessories for ladle dryers and heaters:
• Add-on for ladle pouring sprout
• RHH cable set (5 m / 197 inches)
• Thermocouples
• Lifting device

H

The control system can handle most of today’s common
communication protocols such as Modbus, Profibus,
Profinet and Ethernet IP.
