Mill utilization is a measure of the percentage of time that the mill is rolling steel. The truest measure of performance is as a percentage of calendar time. Factors that influence utilization are maintenance outages, scheduled and unscheduled holiday outages, downtime for cobble clearing, roll and pass changes, excess billet gap, and other factors that create time …

rolling mills, for ever more sophisticated flatness control has increased dramatically. ABB has, there-fore, in collaboration with customers, continuous-ly developed the Stressometer system →3. The improvements enable mill operators to fully utilize the rolling mill to produce a high-quality strip with maximum yield while keeping maintenance ...

Tactile. The contact strip thickness gauges that measure the thickness of the strip with a precision in the micrometer range are renowned for their exceptional reliability. Over a thousand contact strip thickness gauges bear evidence to the worldwide success of the Vollmer contact gauges. They still form part of the initial equipment of new mills even today.

To measure small diameter rolls (Sendzimir Mills). PRO-MIC Rolling Caliper Opposed probe systems for high-precision measurement needs. What's New. The latest updates from PRO-MIC. PRO-MIC Store PRO-MIC now has an online store! Order batteries, cables, probes, contact tips, …

Hot Rolling Mill temperature Measurement. The Hot Rolling Mill is used to reheat shapes of steel to soften them enough so that they can be rolled thinner and longer through a series of rolling stands. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.

Cold Rolling Mill Temperature Measurement. At the cold mill the rolls and strip become heated through the heat of deformation. As the rolls heat they expand. If the middle of the roll heats more than the edge, then thermal crowning occurs, …

strand rod mills, combined bar/rod mills or profile mills · Perfect diagnostics of rolling process: over-/ under-fill, ovality, tension/compression, axial roller shift,rollerexcentricity,rollerwearandlong term trends The measuring range is variable from 0.5 to 180 mm, depending on the application needs. The gauge head is equipped with crane

finishing mills, which will roll the steel in tandem with one another. The workhorse roughing mill has 135" wide rolls for rolling 'broadside' (as the first roughing mill is commonly called) to make a slab wider. A 5,000 hp motor drives 42"-diameter work-rolls through 28:1 gears to reduce the slab's thickness by as much as 2-½".

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.

COLLIN Roll Mills M Measuring are essential for all processes in development and production control. The accuracy of the setting parameters and the large number of measuring devices allow a reproducible determination of characteristic material data, whereby the creation of optimal setting parameters for all production machines is supported.

The AR700 series contains models with measurement ranges from 0.125 inches up to 50 inches and resolutions as low as one-sixth of a micron. With sampling speeds up to 9.4kHz and linearity to within 0.03% of the measurement range, the AR700 is a versatile sensor for many challenging applications. Read more

36 According to IEA (2007), globally, typical hot rolling energy needs are 2 – 2.4 …

Roll chocks in Rolling Mill. Rolling mills for rolling of steel differ in many aspects with each other. The rolling mills are of different sizes and capacities. The mills roll steel materials of different cross-sections, sizes and qualities and in …

Dual Thickness Laser Measurement of Aluminum. In the rolling mill process, the aluminum starts as an ingot. As the ingot gets squeezed down into a thinner and thinner sheet of aluminum, the operator needs to know the thickness of the sheet in order to determine the correct size.

Hot Rolling Mills Use through-process temperature monitoring to gain more insight into the reheat process. Achieving and maintaining the correct temperature through the furnace is crucial in ensuring materials like steel slabs and billets have been uniformly heated during the reheat process at hot rolling mills.

Roller mills are commonly referred to by the type of service they perform. A mill used to crack grain or other types of friable materials may be called a cracking mill. Mills used to flake grains or other products may be called flaking mills or flakers. Roller mills used to grind in a feed mill are commonly referred to as a roller mill or ...

This BFI research focuses on improving throughput in the rolling mills. To this end, equipment of the rolling mill was fitted with additional temperature measuring points and simulation of time-discrete material throughput was carried out. Based on statistical analysis of the system performance, temperature optimization and better procoess coordination was achieved, which …

safety at rolling mills Some degree of hazard is associated with every type of activity in steel industry and about 40% of accidents are attributable to handling of materials. In rolling mills, as compared to other units of a steel industry, much of a steel industry, much of the handling is done by mechanical means and therefore, hazards due to handling are less.

Many methods are available for the systematic analysis of the hazards usually present in the rolling mills. There are two basic types of risk analysis methods. One is called the 'deductive analysis method' (top down) and the other is …

The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.
