HOT ROLLING MILLS. In a hot rolling mill process, the steel gets heated at extremely high temperature, which is generally above 1100°C. BLH Nobel can provide sensors and complete measurement systems that are highly durable and withstand the extremely harsh environment in the steel industry production sites.

In a metal rolling process, rolls, stands, bearings, housing, motors, and other mechanical equipment are all a necessary part of the manufacturing operation. The place where all the equipment for metal rolling manufacture is set up is called a rolling mill. Rolling mills often vary in the type, number, and position of rolls.

Using a block mill, which drives multiple rolling mills and has been used on 100m/s class wire rod lines, as the bar steel finishing mill, will achieve speeds far beyond the finishing speed of about 20m/s that was the limit of conventional mills.

ing mill. The behavior of width spread in a finishing mill depends on effects in roll bite and on the creep defor-mation between the stands, whereby the width spread in roll bite is influenced, for example, by thickness reduc - tion, front and back tension, and the change-of-strip-crown ratio. The creep deformation between the stands depends on ...

COLD ROLLING MILLS: STRIP TENSION. High consistency in rolling mill operation requires a high accuracy in tension measurement. The BLH Nobel strip tension systems for rolling mills measures the actual resultant strip tension force, as opposed to measuring the indirect force given by the electrical drives current, increasing measuring accuracy and reactivity.

Extensometers are simple, economical sensors attached to rolling mill housings to measure the strain in the housing posts resulting from roll force. Roll force can be derived from these measurements, but due to outside influences, these calculated results can never be as accurate as direct load cell force measurement.

Large amount of flexibility is available in modern long products rolling mills. These mills are normally continuous mills consisting of three sets of rolling stands namely (i) roughing group of stands, (ii) intermediate group of stands and (iii) finishing group of stands. The input material for these mills is normally billet.

NEW STRIP-TENSION CONTROL FOR BETTER THICKNESS PERFORMANCE AT FINISHING MILLS Paper number: 79 Principal author: Daniel Kotzian The stable and reliable rolling of thin strip in the finishing mill of linked casting and rolling processes such as Arvedi ESP (endless strip production) and Compact Strip Production (CSP), or in conventional

The rolling mill is called cross-country rolling mill because of arrangement of the roll stands. In these rolling mills, the centre lines of the roll stands are parallel to each other and the material being rolled is shifted perpendicular to the rolling directions.

If the mill rolls 800,000 tons per year, it runs at an average production rate of 114.16 tons/hour. If the utilization can be improved by 1 %, the available rolling hours is 365 x 24 x 0.81 = 7096.6, creating 87.6 extra rolling hours. At 114.16 tons/hour that is an additional 10,000 tons can be rolled.

Three-High Rolling Mills: In this mill, the three rolls stand in parallel one by others. The rolls are rotating in opposite directions. In this mill, between the first and the second rolls, the material passes. If the second roll rotates in a direction then the bottom roll rotates in another direction.

Reducing the roll gap increases the roll pressure to p3. Gage control in multiple rolling mills is achieved through measurement of strip thickness using x-ray gage and adjusting the strip tension using feedback control system. 1.8 Rolling defects: Mill spring is a defect in which the rolled sheet is thicker than the required thickness because,
