Background technology
After high-speed wire production line rolling, need by Laying head by wire rod lopping, be then laid on conveyor roller and transport to collecting region.Now, wire rod is organized and is not also reached final tissue, also needs the wire rod in stage to this to cool.
Traditional stelmor controls wire rod and is cooled to the array blower fan adopted below roller-way, carries out pressure cooling to wire rod.By changing the number of units of blower fan, wind turbine allocation of the amount of air and the roller-way speed of service, regulate the intensity of cooling of wire rod, thus make different steel grade, the wire rod of different-diameter obtains required structure and properties.But, because wire rod is after Laying head lopping, tiling of spirality formula one being enclosed the land mutually overlaps and runs transmission forward, wire rod overlapping density in overlapped points place is larger, cooling velocity is slow, it is poor with the structure property of circle that result causes wire rod, the mass intensity test stone of rolled piece is often reference with minimum intensity, the intensity of overlapped points determines the final quality of rolled piece wire rod, though other position of wire rod has higher intensity but not use, cause larger strength character waste, and then cause the waste of rolling cost.
At present, also use many methods abroad and attempt to solve the problem, but be not all resolved.As adopted " Optiflox device " to the air blast of overlapped points emphasis." Optiflox device " carries out assigned unit to cooling air, air quantity is more assigned to roller-way both sides, i.e. wire rod edge, on the position that overlapped points is intensive; Or by carrying out accelerating cooling to the mode of overlapped points water spray, as long as but overlapped points does not produce the changing of the relative positions or the changing of the relative positions is few, then can produce cooling velocity difference, the wire rod structure property finally obtained is fluctuated large, the intensity difference of overlapped points and non-overlapping point can reach 12-15Mpa, even 20-25Mpa, mill speed is higher, and wire rod is closeer, gauge or diameter of wire is thicker, and the intensity difference of generation is larger, if and employing atomized water spray mode more can make wire rod produce corrosion, has a strong impact on quality further.
Therefore, how realizing improving wire rod overlapped points intensity is those skilled in the art's technical problems urgently to be resolved hurrily.
