The mathematical and physical modeling of turbulent recirculating flows

Abstract: A physical model has been constructed to represent turbulent recirculating flows that occur in argon-stirred ladles. By using a mechanically driven circulating system including a moving tube it was possible to generate flow fields such that all the boundary conditions could be defined unambiguously. The velocity fields developed in the system and the spatial distribution of the turbulent kinetic energy were measured experimentally using a laserdoppler anemometer. The experimental measurements were found to be in good agreement with predictions based on theK-W model for turbulent recirculating flows, provided appropriate wall functions were used. A simplified model was also described in the paper, for representing the transient decay of turbulence in teemed systems or in bubble stirred vessels after the agitation had been terminated. This model, which in essence involved the use of a simple algebraic relationship, gave semiquantitative agreement with measurements.

Low carbon high yield and tensile strength steel and method of manufacture

Abstract: A process for producing a killed, low carbon, columbium, boron alloy steel characterized by high strength and an unbanded ferrous microstructure in the as-rolled condition. The steel is hot rolled to form an intermediate section before the steel temperature reaches 1650° F. Below 1650° F, the steel is further reduced with a total minimum reduction of 50% in one embodiment, and 35% in a second embodiment, and in the Ar 3 -Ar 1 temperature range, reduction is a plurality of reduction passes under conditions to permit substantial recrystallization of deformed grains after each pass, with a finishing temperature between 1100°-1150° F in one embodiment, and a finishing temperature between 1350° F and Ar 1 in a second embodiment.

Hoisting hooks used to lift, transport and dump metallurgical ladles

Abstract: The hoisting hook assembly of this invention comprises a pair of parallel hook arms connected at their upper end to a bail with the hook arms each having an upper hook portion and a lower hook portion adapted to engage a single pair of ladle trunnion pins This assembly permits existing cranes to transport and invert large ladles
