The use of resistance furnace transformer

Resistance furnace transformer for mechanical parts heating, heat treatment, powder metallurgy sintering, non-ferrous metal melting and other resistance furnace and salt bath furnace. Since the resistance of the heating element is too small, or the resistance of the heating element changes too much during the heating process, it is necessary to equip the furnace and the power grid with a resistance furnace transformer to reduce and adjust the input voltage of the electric furnace.
Small capacity, low voltage resistance furnace transformer and salt bath furnace transformer are mostly dry type transformers, with case, natural cooling; medium capacity (hundreds to thousands of volts) resistance furnace transformer Mostly oil-immersed self-cooling transformers; large-capacity is forced oil circulating water-cooled transformers.
