  • Patent number: 6035682
    Abstract: Method and respective hot rolling plant for the continuous production of bars, iron rods or wire, of the type in which the rolled section is cut longitudinally in which: the result is a thin flat bloom (A) with large flat (B) with a thickness close to that of the maximum section of the bar, iron rod or wire to be obtained and with a width equal to at least one multiple of said maximum section; said large flat (B) is further rolled by opposite annularly grooved rolls (23), to shape in contra-opposition the opposite buckled surfaces and recesses in order to bring the section of large flat to the shape of ovals or lozenges one connected to the other for a very thin rolling thickness between the section of one and the section of the other in correspondence of the minimum of said opposite recesses (C); said sections are longitudinally separated in correspondence of the respective thickness minimum, creating a bed of rod sections (D) in continuous advancement, in which each rod section makes up the bar or iron rod

  • Patent number: 5433264
    Abstract: Assembly to wind-unwind thin slabs which cooperates with a continuous casting plant (11) producing thin slabs (12) and is positioned on the same axis as that plant (11), a heating and temperature-equalization furnace (17) being included upstream of the winding-unwinding assembly (10), at least one pair of drawing rolls (23) cooperating with the winding-unwinding assembly (10), which comprises two coiling-uncoiling units (20a-20b) positioned circumferentially equidistant from, and on, a base plate (21) able to rotate about a substantially central vertical axis, one of the units (20a-20b) taking over alternately the position and function of the other unit (20a-20b) and viceversa, each coiling-uncoiling unit (20a-20b) being equipped with its own lead-in guide (26) and powered rolls (28), the powered rolls (28) being coplanar and positioned below the thin slab (12) and cooperating with a curvature-imparting roll (29), which can be moved from a position of cooperation with, and between the powered rolls (28) to an
