The three high rolling mill utilizes the principle of passing the work back and forth to achieve a series of reductions. Unlike the two high reversing mill, the three high mill has three rolls that always spin in the same direction. An elevator mechanism lifts and lowers the work so that it can be passed back and forth through the rolls.
Wire and Rod Drawing Process for Steel. Drawing of wire from steel rod is a metal working process used for the reduction of the cross-section of the rod. Similarly rods are drawn from steel rounds of larger diameters. During drawing the volume remains the same and hence there is increased in the length of the drawn wire or rod.
HSM Finishing Work Rolls for chequered plates with different profile patterns. ... Rolling mill mechanical components and spares can be produced by applying reverse engineering technique. ... Tool Steel and TiC are utilized by high speed bar, wire rod and sizing mills. Exactly machined rollers are provided with bearings upon request.
The laying head of the high-speed wire rod mill is mainly composed of transmission devices, tubular shafts, laying pipes, laying disk,s and bearing seats. After the wire is rolled out from the high-speed finishing mill, it is fed into the tubular shaft of the laying head by the pinch roll in front of the laying head through the conduit.
The developments taken place in the wire-rod production in the past three decades is discussed. It is analyzed that the steelmaking heats and billet size have grown while the demand on the mill ...
Wire Rod Block Mill is composed of top crossed 45°high-speed wire-rod mills / finishing mills. The finishing mill / wire rod mill is located in high-speed wire-rod workshop. Through several unit rack the continuous micro-tension rolling mill will be transported upstream Ø17 ~Ø21mm of rolling, rolling become Ø5.5 ~ Ø16mm finished wire.
The failure analysis on the premature wear of a "Laying Head Pipe" in a Wire Rod Mill has been presented. The hot-rolled wire rods subsequent to finish rolling pass through the "Laying Head Pipe" which rotates and lays the wire rods in the form of coils for air cooling to achieve the final properties. A worn-out pipe and a thermo-mechanically treated (TMT) re-bar have been analyzed ...
Russula supplies high speed wire rod mill. After the successful supply and commissioning of the 4 slitting bar mill in 2015, Russula supplied the high speed wire rod line for Gerdau's (formerly Silat) plant in Primavera in Caucaia, in the state of Ceará, Brazil. The combined mill is designed for an annual capacity of 600,000 tpy.

Block mills. Using a block mill, which drives multiple rolling mills and has been used on 100m/s class wire rod lines, as the bar steel finishing mill, will achieve speeds far beyond the finishing speed of about 20m/s that was the limit of conventional mills. Rolling using ultra-hard rolls provides advantages such as precise measurements and ...

A wide range of high-rigidity housing mills are available, including HSCD700, HSCD610, HSCD560, HSCD480 and HSCD430. These six models can be used in a wide array of applications across the rolling process from acting as a roughing mill through to acting as a pre-finishing mill in either continuous rod rolling or high-speed wire rolling.
capstan is matched to the wire size of a new die, capstan speed will be faster than the wire speed as the wire diameter increases. This increased capstan speed will apply high tensile stress on the wire, often breaking the wire. Therefore, capstans in multi-pass drawing machines are designed so that the wire slips on the capstan as the dies ...
