A valve housing has butt pipes for connection to a pipeline for defining therewith a passage for a flow of a fluid being conveyed, preferably of a slurry. A plurality of ribs are provided along the passage on the lower portion of the wall thereof, each rib extending transversely of the passage. Each rib is of a tear-shaped configuration in its section taken along the longitudinal centerline of the passage, the enlarged portion of the rib facing toward the incoming flow of a fluid being conveyed.

An electroslag remelting and surfacing apparatus having a cooled mould comprising a plurality of superimposed sleeves which are electrically insulated from one another. The top sleeve of the mould, being substantially a non-consumable electrode, has a current lead and a lining of electrically conducting material. If provided with a radial electrically insulating layer, it may also serve as a single-coil inductor adapted to impart a rotary motion to the slag pool.

A tank furnace comprises a first container containing a molten flux and connected with a hoisting mechanism, and a second container containing a molten coating metal. The second container is stationary mounted so as to be placed inside the first container when in its upper position. The mechanism for advancing articles into the coating zone is connected with a device for controlling the depth of immersion of the articles being coated. The first container is fitted with electrodes.
