A new concept of "non-carbon metallurgy by solar energy photovoltaic technology" is proposed

according to the research requirement its experimental system structure and parameters are defined and I kg-capacity experimental furnace is designed and manufactured. With defined process parameters and balance-calculated charging mass and heat energy in smelting process

the high temperature smelting test of non-carbon metallurgy by solar energy photovoltaic technology '' has been carried out. Test results show that the designed system meets the requirement of smelting and has better stability and operability. With exergy calculation it is obtained that the utilization of solar photovoltaic technology' is a process to increase itself exergy value.
