In rolling mills it is crucial that the material and roll speeds are determined correctly. The in-plant speed measurement can be checked easily, quickly and safely using a non-contact laser velocimeter.
cking the rolling gap to the infeed thickness in order to achieve a reduced, constant thickness of the output strip in the finished product. There is the transport time of the strip from the strip thickness measurement to the rolling gap must be measured and taken into account.
Mar 11, 2005018332Hot rolling mills suffer from severe torsional vibrations in particular working conditions thin thickness. These vibrations are often explained as the result of an exogenous disturbance amplified by a resonance effect.
The voltage THD measurement was in the range of 1.51 to 8.17 of the fundament voltage. The voltage range is due to the load level of the mill stands a machine that quotmillsquot or rolls the steel into various shapes or different thickness.
Flatness measurement in rolling mills The requirements on the surface quality of rolled sheet metal are continually increasing. This may be steel sheet which is used, for example, for stainless steel fronts in kitchens, or also aluminum sheet used in the automotive field.
Improve operations, increase mill throughput and take preemptive corrective action with real time process control data from Thermo Scientific Gauges for Hot Strip Mills.
This type of control is easily adaptable in computer control of cold rolling mills. Rolling Practice VS Anisotropy in Sheet Metal The measurement of planer anisotropy and anisotropy ratio. The anisotropy ratio is useful in getting deeper draws while planer anisotropy gives rise to earnings during drawing.
Jun 30, 2000018332The authors present different types of rolling mills and the defining physical analytical parameters.They also discuss the effects of hot rolling on steel and the role of lubrication and thermomechanical treatments to minimize these effects. This book presents qualitative and quantitative advances in cost-effective steel production.
Hot Rolling Mills In metalworking, rolling is a metal forming process in which metal stock is preheated up to 1300176C 2400176F and passed through rollers to reduce thickness. Hot rolling processes include pre-heating furnaces, scale breakers, slab scale, rough stand, finishing stand and cooling lines.
A rolling mill for rolling strip in which one of its rolls serves both as a mill roll and as a gauge andor profile measuring roll.
Gear systems for cold rolling mills The surface finish of cold-rolled sheet is the most important quality criterion of the cold rolling process. To achieve a perfect surface finish you need to eliminate vibrations as far as possible from the whole drive system.
ABB has many years of experience of installing load cells in all types of rolling mills. To achieve the best possible measurement results, certain basic rules must be observed during the installation of the load cell The entire force must pass through the load cell.
HOT ROLLING ROLLING MILLS TEMPERATURE MEASUREMENT. THE OPPORTUNITY. The primary function of the hot strip mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer and finally coiling up the lengthened steel sheet for transport to the next process.
Request PDF Velocity Measurement in Rolling Mills using Impedance Analysis Rolling mills are continually improved and opti-mized by implementing innovative technology to decrease costs and scrap.
Cold rolling mill is used to roll raw material thickness 4 mm, width 800 mm, made of plain carbon steel, low alloy steel, stainless s Cold Rolling Mill Contact thickness gauge is a kind of high precision metal plate thickness online measurement equipment, which can rapidly and accurately.
