Abstract: A method for producing a steel strip which has been cast as a stand in a cooled oscillating continuous chill mould, comprises squeezing the strand emerging from the chill mould until it has a first cross-sectional thickness (40-50 mm), followed by hot rolling the strand until it has a second cross-sectional thickness (2-25 mm). Deviations in the normal path of travel of the strand following hot rolling are corrected by adjusting the thickness to which the strand is subjected during the first squeezing step.

Abstract: Molten steel is continuously teemed into a casting passage to establish a bath of molten steel in the passage. The molten steel is partially solidified in the casting passage to form a strand having a plurality of bulges which are uniformly distributed circumferentially of the strand. The strand is continuously withdrawn from the casting passage and the bulges are deformed during strand withdrawal so as to reduce bulge size. The amount of deformation is regulated by varying the bath level as a function of one or more casting parameters.

Alternatively, the spindle can operate in a reduced load condition permanently in which case the desired gap can be set continuously using the reduced-load spindle with only a small spindle adjustment force being necessary.

Abstract: Multiple pairs of pinch rolls are used to advance a rod product along a pathway following a continuously casting and rolling system. Each pinch roll pair exerts a force normal to the rod of less than the amount necessary to substantially degrade the yield strength characteristics of the finished rod. Multiple driven pinch roll pairs cooperate to advance the rod by compressive engagement and accomplish the work of one or two pairs of pinch rolls to minimize work hardening and/or plastic deformation, which can result in an increase in yield strength. Yield strength characteristics are thus improved while the continuous rod product is still advanced and guided at very high speed along a pathway from a horizontal to a vertical direction.

Abstract: In a continuous hot rolling system, at least one melt-cut torch is set in a predetermined positional relationship with respect to a trailing end of a preceding hot material and a leading end of an adjacent succeeding hot material. An injected flow of cutting gas from the melt-cut torch is blown against a portion of at least one of the trailing end of the preceding material and the leading end of the succeeding material to melt-cut the portion.

This joining may be made with respect to slabs before rough rolling, or may be made with respect to bars after rough rolling.

The roll speed of the horizontal mill disposed on the delivery side is controlled to be higher than that of the horizontal mill disposed on the entry side. This enables preventing of failure in the shape of the rolled material.
