PROCESS FOR HOT-ROLLING SMALL STRAP -LIKE STEEL PROFILES

摘要

The invention relates to a process for hot-rolling the small strap-like steel profiles by passing the bar-shaped blank (1) having round cross-section between the flat-barrel cylinders of a small iron-rolling mill and then through a prefinal pass (2) and a final pass (3) of a specific shape, wherein the product (1) resulting from the blank (1) passed between the flat-barrel cylinders is passed through the prefinal passes (2) and final passes (3) at a rolling speed of 10 ... 16 m/min and with coefficients of reduction of 1.08 ... 1.54 per passing.
