By suppressing the oxidation of aluminum molten metal and the growth of oxide films, we have developed a hybrid-type (electric heating + combustion) aluminum continuous melting holding furnace based on the Freedom concept, which aims to free you from the daily difficult cleaning tasks of the holding chamber. *Patent obtained. Even after three months without cleaning, a simple cleaning restores it to its original state... Because it is a hybrid method based on the Freedom concept, the electricity consumption of the holding heater is reduced by about 26% (case study). Because it is a hybrid method based on the Freedom concept, the oxidation rate in the holding chamber has decreased from the conventional 0.6% to 0.007% (case study).
