Thermal insulation screen transparent to magnetic flux, intended to isolate an electromagnetic inductor with a transverse or pseudo-transverse field, from the radiation of a heated product (1), the thermal screen being made up of a matrix of blocks (7) made of a thermally insulating material and of a plurality of tubes (8) cooled by the circulation of a fluid, these tubes being imprisoned in said matrix of blocks and the tubes and the blocks being held in place by a support. The screen includes, behind the blocks, heat-conducting means (10) placed so as to intercept the heat flux passing through the blocks, these conducting means being thermally coupled to the cooled tubes (8) for discharging the heat flux into the tubes.
