Abstract: A shell (10) acts as a transporting shoe for steel ingots, which are pushed through a preferably tubular induction furnace for inductive heating for the purpose of producing seamless tubes by the extrusion process. The shell (10) is formed in such a way that it partially reaches around the contour of the steel ingot to be heated. The shell is provided at one end leading in the pushing-through direction or transporting direction, with a shoulder (12), which extends at an angle to the transporting direction, against which the steel ingot rests in such a way that the pushed-through steel ingot takes the shell (10) along with it. A method for inductively heating steel ingots uses a shell (10) as described.
