The high-speed wire rod mill finishing unit is an important factor to ensure high-precision rolling of wire rods. Therefore, tungsten carbide roll rings with a hardness of 82-90HSD must be used in the finishing unit of the high-speed wire rod mill. Otherwise, the rolling speed and the wear resistance of the roll ring cannot be guaranteed.

The bulk density of a new or freshly culled (i.e., broken rods removed), graded rod charge is 390 lbs. per cubic foot (5.0 kg/m³) Due to lack of culling and the greater tendency for rods to break as mills increase in size, the estimated bulk density of the rod charge must be reduced accordingly (Rowland, 1982).
