semi-finished products like wire rod. Standard practice is to inspect the product during further processing and finishing of individual parts in the cold state. The general trend today is for testing to also take place on the hot product in the rolling mill itself (Figure 1).
Development Direction of Wire Rod Rolling Mill. 1. Flexible Rolling Technology: In order to reduce the shutdown time of wire rod rolling mill, people have studied the flexible rolling technology, which rapidly changes the rolling schedule and product specifications by means of non-pass rolling and common pass rolling.. 2. High Precision Rolling: The diameter tolerance of wire rod has a great
than larger roll diameters in a given rolling process. In strip rolling mills, rolls with small diameters are used to reduce forces. As these small rolls tend to bend, backup rolls are used for support (see Fig. 3). In wire mills, the separating forces are lower due to smaller width of the rolled material and support rolls are usually not found.
The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.
