Application

l          HARDUN series coil metal core vacuum gas protection annealing furnaces are used for annealing of EI or step form metal core, Such as circular metal core、mutual induction metal core、metal core of transformer and electric machine and non-metallic magnetic materials. After annealing, the metal core is bright and hasn’t been oxidized, and the inner stress is relieved. The atomics of metal is regular arranged, then the magnetic of silicon steel is increased and metal loss is decreased. 

l          They are used for vacuum gas protection annealing heat treatment of coil metal core、mutual induction metal core. They can completely meet requirements of annealing technology craft and there is no oxidation, the stress is relieved. They are ideal instrument of transformer industry. We can produce furnaces according to specification and dimension of work piece.  

Product characteristics

l          The temperature of HARDUN series coil metal core gas protection annealing furnaces are controlled by procedures, these furnaces can automatically finish the heating-heat preservation-reduce temperature process according to the set values; the temperature is controlled is three areas in furnace gall; There is solid relay to adjust power. 

l          HARDUN series coil metal core gas protection annealing furnaces are convenient for operation, and the technology is reliable、efficient and save energy. They are  ideal instruments of magnetic material、transformer industries.

l          Their temperature showing and limiting differences between ordinary furnaces are that they increase directional radiant, their economy energy effect is obvious and their lives are longer.

l          HARDUN series coil metal core gas protection annealing furnaces inherit merit of practical、reliable and convenient of indirect heated vacuum gas protection pit-type annealing furnaces, and they are new economy and efficient furnaces that meet annealing requirement of certain work piece. The capacity of furnaces is large and can discharge 3-10t annealing work piece and temperature uniformity is fine. There are three zones for temperature control and it can heating – preservation-reduce temperature according to set temperature and automatically controls and records technology craft.
