Electric furnace waste heat boiler system with molten salt overheating function

The utility model provides an electric furnace waste heat boiler system with a molten salt overheating function, and relates to the technical field of waste heat power generation. The electric furnace waste heat boiler system with the molten salt overheating function comprises a low-temperature molten salt tank (1) and a high-temperature molten salt tank (2). A molten salt flue gas heat exchanger (4) and a molten salt steam heat exchanger (8) are arranged between the low-temperature molten salt tank (1) and the high-temperature molten salt tank (2) in parallel. One end of the fused salt flue gas heat exchanger (4) is connected with the electric furnace (3) through a flue, and the other end of the fused salt flue gas heat exchanger (4) is connected with the electric furnace waste heat boiler (5) through a flue; the electric furnace waste heat boiler (5) is also connected with a deaerator (6) and a heat accumulator (7) at the same time; steam generated by the heat accumulator (7) is subjected to heat exchange t
