The invention discloses a blast furnace superconductive cooling waste heat power generation system based on a bias adjustable current source. The system is mainly formed by a blast furnace body (1), a power generation system (12), a steam utilization device, more than one superconductive annular heat transfer ring (2) in layered encircling arrangement along the side wall of the blast furnace body (1), pouring solidification bodies (10) made of wear-resisting heat-shock-resistant anti-permeability coal elastic refractory castables and arranged on each superconductive annular heat transfer ring (2), and lower conduits (32) connected in series with a lower circulation port of each superconductive annular heat transfer ring (2). According to the system, hot water obtained after heat transfer is exported in a concentrated manner through the superconductive annular heat transfer rings embedded in the side wall of the blast furnace body and annular pipeline systems corresponding to the superconductive annular heat transfer rings, so that heat transfer intensity is enhanced, heat transfer efficiency and cooling efficiency are improved, and cooling water temperature is improved from the original 40 DEG C to 250 DEG C; and then, the water is overheated to a temperature of 400 DEG C through twice applications of the superconductive annular heat transfer rings, and thus the cooling waste heat is allowed to be utilized for power generation.
