Abstract: An electrode case used to make a self-baking electrode that is consumed in a reducing arc furnace and the electrode made therefrom is described. The electrode case comprises an outer sleeve and a plurality of fins. The outer sleeve is divided into multiple sleeve sections made from a first metal, such that each sleeve section has an outer and inner surface, the multiple sleeve sections capable of being stacked together to form the outer sleeve. The plurality of fins is divided into multiple fin sections made from a second metal, such that each fin section is mechanically coupled to the inner surface of one sleeve section along its length and project radially therefrom along its width. Each fin section has an upper interface region, a central support region, and a lower interface region; the upper, central, and lower support regions having a lattice structure with at least 10% open area.

Abstract: A clamp comprising a band (10) having, at one end, a pair of axially spaced jaws (16, 18) comprising an upper jaw (16) and a lower jaw (18) and, at the other end, a tongue (28) that can be inserted between the jaws. The tongue has an upper surface and a lower surface and the top jaw (16) has a lower surface that includes a single engagement tooth (20). The upper surface of the tongue includes an engagement tooth (29) having a cavity (30) behind it that can accommodate the engagement tooth (20) of the upper jaw to hold the clamp in a closed position. The lower surface (48) of the tongue is provided with a recess (40) that accommodates the lower jaw (18) when the clamp is in the said closed position.
