Off-gas hood for a basic oxygen furnace and method of repair

Abstract: The invention is directed to water-cooled furnace hoods that exhaust gases away from a work area, and in particular, it is directed to an off-gas hood for use with a basic oxygen furnace (BOF). The furnace hood includes an assemblage of panels fastened together to form a flue positioned above a BOF at a location to receive gases generated by the furnace. Each panel includes an inlet header for receiving cooling water, an outlet header for discharging cooling water, and a plurality of tubes, such as a tube-bar-tube membrane, extending between the inlet and outlet headers to distribute cooling water between the headers. Jumper pipes extend between outlet headers and inlet headers located in adjacent panels. The jumper pipes distribute cooling between adjacent panels and thereby provide a continous flow of cooling water along the length of the flue. The invention is also directed to a method of replacing the panels located in the assemblage of panels that make up the flue.

Method and means for corrosion protection of cables exposed to underground environments

Abstract: Stranded cable such as flexible pumping strand used for oil wells is protected from deterioration in corrosive underground and underwater environments by jacketing the cable with a plastic sheath and pumping a corrosion-inhibiting liquid having a specific gravity similar to that of the immediate underground environment from the surface through the strand and out the lower end of the strand while maintaining a slight positive pressure within the strand or cable.

Apparatus and method for vacuum treating molten steel

Abstract: An apparatus for vacuum treating molten steel includes a ladle having a sidewall, a substantially circular closed bottom, and an open top. A first gas injector is operably associated with the bottom for introducing a supply of a selected first gas into the ladle. A barrel degasser is operably associated with the ladle for being introduced into the ladle through the open top. The degasser includes a generally cylindrical shell having a single substantially continuous diameter opening them through defining a treatment space. A second gas injector is radially directed and operably associated with the shell for communicating with the treatment space. A source of the first gas is in flow communication with the first and second injectors. A vacuum source is operably associated with the barrel degasser for applying a vacuum to the treatment space.

As-worked, heat treated cold-workable hypoeutectoid steel

Abstract: Hypoeutectoid steels are worked within a temperature range of between the A 1 temperature to 150° F. below the A 1 temperature. The cross-sectional area of the steels is reduced by not less than 60% during working. After working, the steels can be heated to about the A 1 temperature to obtain the optimum hardness and ductility for cold-working. The as-worked structure and the heat treated structure are also described.
