Abstract: Metallurgical electrode seal may include a body defining a generally circular open interior, the body defining a gas injection port through a thickness of the body. The seals may include an upper sealing element disposed on an inner surface of the body. The seals may include a lower sealing element disposed on the inner surface of the body. The gas injection port may be positioned between the upper sealing element and the lower sealing element.

Abstract: Methods of coupling anode segments of a metallurgical system may include engaging a clamp with a first anode segment of a first anode stack. The clamp may inhibit the first anode segment from moving in a longitudinal direction. The methods may include disengaging a first stem from a support structure positioned above a metallurgical vessel. The methods may include disengaging the first stem from a top end of the first anode segment. The methods may include coupling a second anode segment to the first anode segment. The methods may include coupling a second stem to a top end of the second anode segment. The methods may include engaging the second stem with the support structure. The methods may include disengaging the clamp from the first anode segment.

Abstract: Some aspects relate to a toroidal field (TF) coil for a tokamak. The TF coil includes a first inner leg having teeth on a side of the first inner leg. The corresponds to an interface between the TF coil and a second TF coil. The teeth extend along a direction having a component in a radial direction of the tokamak. The teeth are configured to mechanically engage with second teeth of a second inner leg of the second TF coil.
