Abstract

The high-precision control of the special cooling process of the hot-rolled strip steel head is an important means for stable production of the production line and improvement of the finished product rate. It is also a key technical problem for cooling control after rolling. Aimed at the process requirements of different products under ultra-fast cooling conditions and the characteristics of cooling equipment layout after rolling, the hot-rolled strip steel laminar cooling zone has been developed with heads that are not cold, ultra-fast cold heads with weak heads, and pressure-based preloads. The compensated head cold control strategy achieves high-precision control of the special cooling section of the strip head. With the characteristics of flow regulation, ultra-fast and energy-saving high-precision hydraulic control strategies and ultra-fast control methods for cold manifold flow rates have been developed.
