Embodiment Construction

[0034] main reference figure 1 , 10 as a whole indicates a compact reversible universal rolling mill for the production of medium and large profiles.

[0035] As shown, according to the present invention, a reversing universal rolling mill 10 is arranged such that a finishing rolling universal stand 11 is provided as the final additional stand of a reversing intermediate unit 12 which carries across the bar 17 to be processed. roller table 13 .

[0036] The reversible intermediate unit 12 includes a first universal reducing stand 14 , a two-roller stand 15 and a second reducing universal stand 16 .

[0037] The function of this additional stand 11 does not change, it is always and exclusively used for finishing rolling. Thus, the stands 11 are always open during intermediate rolling passes and are closed only before the bar completes the last rolling pass in the production cycle.

[0038] In the alternative, figure 1 Only the arrow F of this solution appears in , the stand...

Abstract

A compact reversible universal mill for producing medium-large sections has a universal reducing stand, a two-high stand and a universal stand to create a reversible intermediate unit across a roller way carrying a bar being worked. Provided immediately downstream of the reversible intermediate unit is a finishing stand being the final additional stand and extending also across the shared roller way or respectively moveable perpendicularly in relation to the roller way. The finishing stand is kept open or respectively closed during intermediate passes of a production cycle and being closed or respectively used on the roller way only before the bar completes the final pass of the production cycle.

Description

technical field [0001] The invention relates to a compact reversible universal rolling mill for the production of medium and large sections. Background technique [0002] Over the past decade, economic development and research have increased the application of increasingly innovative civil engineering solutions that make extensive use of profiles to improve versatility, light weight and resilience, and they have enabled steel manufacturers to compete in the market Seeking solutions for the production of this profile. In fact, the use of lightweight, resilient structures is becoming an essential requirement for the construction of tall buildings and increasingly extreme architectural solutions. [0003] Population growth in already densely populated areas has led to the construction of taller and taller skyscrapers, requiring buildings that are both resilient and rigid. [0004] In this regard, therefore, the market demand for medium and large profiles has increased signifi...
