Aluminium holding furnaces
The Krownmatic is a furnace for aluminium holding without crucible, heated by means of electrical resistances of silicon carbide that includes an electronic dosing system. The furnace housing is thermally insulated and it is manufactured in carbon steel. The furnace lining is made of refractory concrete resistant to aluminium; this concrete has great toughness and hardness. Due to the refractories high quality and with proper maintenance being carried out, the furnace can reach a more than 10 year useful life.
The Krown dosing furnace has been developed to obtain high quality castings with minimum consumption, notwithstanding all the required safety measures to be taken into account.
