TRANSPORT LADLES

Transport ladles

The ladles produced by Krown SA are made of perfectly insulated refractories and are equipped with a lid to reduce temperature losses and ensure the safety of operators during the transport of aluminium from the melting furnace to the holding furnace.

We have several models with load capacities from 320 to 960 kg:

PREHEATING SYSTEMS FOR LADLES
KROWN

Pre-heating systems for ladles

To achieve safe transport of liquid aluminium and to maintain its quality, we have two different types of ladle preheating systems: electric and gas. Both types of systems are made of rigid steel frames and lined with high-quality thermal insulation. These systems ensure the correct temperature inside the ladle before the metal is transported.

GAS PREHEATING SYSTEM
The electric preheating system can raise the ladle temperature to 300°C in about 3 hours.

GAS PREHEATING SYSTEM
The gas preheating system allows a maximum temperature inside the transport ladle of 1000 ºC. The normal operating temperature is 660 ºC.
