Description

technical field

[0001] The invention relates to a small-size round steel continuous rolling method. Background technique

[0002] At present, the conventional small round steel and wire bar steel mills at home and abroad are multi-stand rolling mills (the number of stands is generally greater than 12), which is similar to the continuous rolling mill of 6V-H (large stand spacing, large roll diameter, and long roll body length). The rolling mill generally rolls larger-sized round steel, and adopts a single guide wheel D 0 The box-square-ellipse-round hole system, such as figure 1 As shown, the 6V-H continuous rolling mill is arranged alternately between vertical and horizontal, the torsion tendency of the rolled piece is small, and the speed of each stand can be adjusted independently, and the extension can be distributed and extended according to the approximately equal load of each motor. However, there are limitations in the specification range of round steel products. Ac...
