Patent Description:
In the process of high-speed wire production, it is of great importance to improve the comprehensive properties of steel. However, there are many methods to homogenize the microstructure in steel and improve its composition segregation, which mainly include controlling the solidification structure of steel, controlling the cooling rate and adjusting the alloy elements in the steelmaking process. A heating system and a controlled cooling process are included in the rolling process. The controlled cooling process is mainly formulated according to the "C" curve or "CCT" curve of different steel grades. The running speed of the roller way body and different air volumes distributed to the area are controlled by motor power and an Optiflex device, respectively. As shown in <FIG>, under the existing Stelmor air-cooling process, the coils are distributed in a continuous circle on the air-cooling roller way body, so that the stacking thickness of overlapping points is large at both sides and the stacking thickness is small in the middle, the stacking thickness of the whole uncoiled circle is non-uniform, and the temperature at the position of the edge overlapping points fluctuates greatly, which will not only lead to non-uniform heating of the overlapping points, but also affect the performance of the finished wire products in the same coil.

PTL1 (<CIT>) describes an apparatus and a method of cooling wire in a wire-forming machine comprises blowing air diagonally from above and below and from the sides laterally to cool the wire.

PTL2 (<CIT> <NUM>) describes a uniform quenching apparatus and method for a hot rolled wire rod.

PTL3 (<CIT>) describes a method for transporting hot-rolled wire rod and an apparatus therefore.
