A method and a regulating device for regulating a rolling process, wherein a rolling material is rolled in a rolling gap between two working rollers of a rolling stand. A target forward slip value (f.sub.s) for a forward slip (f) of the rolling material is specified, and an actual forward slip value (f.sub.M) of the forward slip (f) of the rolling material is ascertained. The forward slip (f) of the rolling material is regulated to the target forward slip value (f.sub.s) in that a lubricant rate (u.sub.R) of a lubricant is applied to the rolling material and/or at least one working roller depending on the actual forward slip value (f.sub.M) and the target forward slip value (f.sub.s).

A framework cooler (20) for cooling a steel strip (50), installed in a roller framework (11), in place of the work rolls (5) and their associated installation pieces (5a and 5b). The framework cooler (20) is sized to be installed into the roller framework (11) through the operator-side roller stands (1) of the roller framework (11). The cooler (20) includes a lower (21b) and an upper water tank (21a), each having a connection (22) for a coolant, and includes a plurality of cooling nozzles (23), or cooling tubes (23a) arranged in the depth direction (T) of the framework cooler (20) or at least one cooling slot (24) extending in the depth direction (T). The bottom and top sides of the steel strip (50) may be cooled.

The present cooling device includes: when cooling regions obtained by dividing an entire cooling region into a plurality of portions in a steel sheet conveyance direction and three or more portions in a width direction are set as divided cooling surfaces, a cooling water nozzle 23 and a switching device that switches between collision and non-collision of cooling water jetted from the cooling water nozzle 23 with the divided cooling surface, the cooling water nozzle 23 and the switching device provided for each of the divided cooling surfaces; and a control device that controls operation of the switching device based on a width-direction temperature distribution.

An on-line oil injection lubrication system of a small-caliber cold pipe blank unit comprises at least one intelligent oil supply assembly. The intelligent oil supply assembly comprises an upper industrial personal computer, a vector frequency converter and a hydraulic pump. The upper industrial personal computer adjusts the quantity of oil supplied by the hydraulic pump to the pipe blank inner hole oil injection assembly and/or the pipe blank outer surface oil injection assembly through the vector frequency converter. The on-line oil injection lubrication system can remarkably improve the quality of inner and outer surfaces of small-caliber stainless steel pipes and effectively solves various surface quality problems such as rolling burrs, rolling folds and micro-cracks caused by oil loss of the inner and outer surfaces of the small-caliber stainless steel pipes during the large-deformation rolling process.
