METHOD AND RESPECTIVE HOT ROLLING-MILL PLANT FOR THE CONTINUOUS PRODUCTION OF BARS, RODS OR WIRE

摘要

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 to be obtained (E); the rolling of the single rod sections (D) continues up to the obtainment of the shape of the finished products (E).
