Abstract

Apparatus for production of elongated rolled products comprising: -a steelmaking station(6) for producing liquid metal having at a first production rate, -a rolling mill (13) having a second production rate -a continuous casting station (11) located between the steelmaking station and the rolling mill (13), the continuous casting station (11) comprising at least two casting lines (21,19), each line being operable to produce elongated intermediate products, wherein:  a first casting line is directly aligned with the rolling mill to feed the rolling mill with casted product, and  at least a second casting line not aligned with the rolling mill and not feeding the rolling mill characterised in that the apparatus further comprises: varying means (27) for varying simultaneously the production rate of the first casting line and the production rate of at least the second casting line depending on the difference between the steelmaking station production rate and the rolling mill production rate.

Abstract

A compact reversible universal mill for producing medium-large sections comprising a universal reducing stand (14), a two-high stand (15) and a universal stand (16) to create a reversible intermediate unit (12) across a roller way (13) carrying a bar (17) being worked, said mill being provided immediately downstream of said reversible intermediate unit (12) with a finishing stand (11) as the final additional stand also across the shared roller way (13) or respectively moveable perpendicularly (according to F) in relation to said roller way (13), the finishing stand (11) being kept open or respectively closed during intermediate passes of the cycle and being closed or respectively used on said roller way (13) only before the bar (17) completes the final pass of the production cycle.

Abstract

The invention concerns a mould for continuous casting of long or flat products, said mould extending along an axis (z) and comprising an internal and an external surface delimiting a mould thicknesses (e, e', e3, e4), the internal surface defining a mould cavity, characterized in that a thickness (e3, e4) of at least a longitudinal element (16A, 16C) of the mould contained in a longitudinal cross-section of the mould (10) increases, at least on a portion of the mould (10), from a point P of minimum thickness in both directions defined by the longitudinal axis (z), the increase depending on a measured or simulated temperature gradients of a test mould in use. The invention also concerns a method of making such a mould, a cooling jacket design to cooperate with such a mould and an assembly comprising such a mould and such a cooling jacket.

Abstract

A machine (10) for winding a wire (40) from a rolling mill into a coil (M), comprising a spindle (11) with a seat (39) for threading the head end of said wire (40) with related binding means (41, 42). Said threading seat (39) and said binding means (41, 42) are linked to an independent cover module (13) that is coupled moveably to said spindle (11).
