Welded integral tube wall for electric steel-smelting furnace

Abstract

A tube wall for forming the heating chamber of an electric steel-smelting furnace is comprised of a plurality of generally parallel tubes each closely juxtaposed with at least one adjacent tube of the plurality and forming therewith an outer groove open away from the chamber and an inner groove open toward the chamber. Welds extend the full length of and substantially fill at least the bases of the outer grooves and each form a gas-tight connection between the respective tubes. In addition tubular transverse reinforcing members are welded to the outside of the wall formed with these tubes, and a coolant is circulated through the reinforcing members through the tubes. Finally lining anchors in the form of hooks have inner ends conforming to the space between adjacent tubes and engage between these tubes to the weld securing them together. The wall is therefore formed simply by the tubes and the welds, and no further gas-tight wall need be provided.
