Nov 27, 2015· A wire rod rolling mill, for example, gradually reduces the cross-sectional area of a starting billet (e.g., 150 mm square, 10-12 meters long) down to a finished rod (as small as 5.0 mm in diameter, 1.93 km long) at high finishing speeds (up to 120 m/sec).
The morgan finishing mill/wire rod mill arranged after the No.3 flying shear area and before the cooling device. Its role is to continuously micro tension rolling by 8 rack unit, the rolled piece 15.7 ~ 20.1mm of rolling mill upstream delivery, rolled into 5.5 ~ 16mm finished wire rod.
The roughing mill is made up of Multiple independent rolling mill stands, Billets heated in the furnace until they glow bright orange-yellow are rolled through one stand at a time to produce transfer bars suitable for finish rolling. High-pressure water-jet nozzles clean the oxidized iron, or scale, from the surface along the way.
The number of stands ranges from 2 to 18. Tandem mills can be either of hot or cold rolling mill types. Defects. In hot rolling, if the temperature of the workpiece is not uniform the flow of the material will occur more in the warmer parts and less in the cooler. If the temperature difference is great enough cracking and tearing can occur.
