Single-stand reversing cold mills. Depending on the product mix, a single-stand cold rolling mill can deliver rolling capacities of 100,000 to 400,000 t/a. Rolling schedules can be carried out with an even or odd number of passes to maximize mill availability and performance.
The purpose of the reversing mill is to reduce the thickness of the steel to the customer's specifications. The hot roll band passes back and forth between the rolls until it reaches the specified thickness. Benefits of reversing mills include: Flexible, low-cost rolling of a wide range of products. Tight strip thickness and shape tolerances.
10%The shape detecting system was successfully used in Angang 1 250 mm HC 6-high reversible cold rolling mill. The precision of shape detecting is 0.2 I and the shape deviation is controlled within 6 I after the close loop shape control is input.
Abstract： With the development of economic and social, the proportion of cold-rolled strip steel in total steel consumption continues to increase.The thickness and shape of strip are important quality indicators. Automatic gauge control is one of the key technologies in strip rolling fields. It is directly related to the product quality and economic efficiency.
Shape Detecting and Shape Control of Cold Rolling Strip Abstract: Based on the shape detecting principle and the DSP (Digital Signal Processing) technology, a high-precision shape detecting system of cold rolling strip is developed to meet industrial application. It was successfully used in Angang 1250 mm HC 6-high reversible cold rolling mill.
