Tower melting furnaces

Krown's tower melting furnaces ensure the lowest aluminium loss and energy consumption, as well as the best production conditions for aluminium foundries, optimising the process and guaranteeing the metal quality required for the manufacture of even structural castings.

We have several models of tower melting furnaces with holding capacities from 750 to 6,000 kg and melting capacities from 350 to 4,000 kg.

MODELS AND TECHNICAL CHARACTERISTICS

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:

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.
