Rolling mill separation forces are measured accurately and conveniently with the RFS4 system. Extensometers on the mill posts or load cells in the screw provide an electrical signal proportional to the mill separation force. A G4 instrument with tailor made software read signals from both sides of the mill and amplify them.
Schaeffler UK was installed on the rolling mill. One sensor was fitted to each of the six spindle support bearing sets, with a plan to connect the two spare sensors to the pinion box. "When we began to analyse the first set of data, we realised that interference from other general plant equipment was masking the true bearing defects.

Jan 14, 2017· Rolling is one of the most important industrial metal forming operations. Hot Rolling is employed for rolling of steel slabs to hot strips in hot strip mills. Like any other hot rolling operations, rolling of hot strip is also a plastic deformation of the material of the slab caused by compressive force applied through a set of rolls.
August 10, 2011 ABB FM (Force Measurement) is using Westermo´s Redfox industrial Ethernet switch with its latest version of Stressometer system for measurement and control of rolling mills. The implementation of the Redfox Industrial device has helped to reduce the number of data communication products needed from six to one, simplifying the ...

He told me that Big River Steel was a technology company that just happens to produce highquality steel. It was David's bold vision to transform Big River Steel into the world's first "smart mill", a mill that could digest piles of data, analyze that data, learn from that data, and continually improve mill .
Aug 09, 2013· Flatness sensing based on pressure measurement is widely used today in the steelmaking industry. In fact, it is the most commonly used technique for flatness measurement in cold rolling mills. Contact flatness sensors for flatrolling mills and production lines are rollers with builtin sensors.
Rolling mills have many different designs and may be standalone pieces of equipment used for processing plate or ingot, or incorporated into full processing lines used for coiltocoil processing. To ensure outgoing material gauge meets a required dimensional tolerance, a rolling mill typically has very accurate positioning feedback.
Roll Force load cells PFVL141. The Millmate Roll Force load cells act as integral parts of the mill stand. The rocksolid Pressductor ® load cell design in combination with the intelligent, reliable communication functions are crucial keys to true roll force measurement.

process control in modern continuous wire rod mills. The interstand tension is a force, resulting from the increase in relative rolling velocity in successive stand and it affects mechanical properties of the product and mill performances [1]. Wire rod mill usually consists of roughing mill, intermediate mill and finishing mill.

POWER IN ROLLING Power is applied to the rolling mill by applying Torque to the rolls and by using roll strip total rolling load is distributed over the arc of contact. However, the total rolling ... x Roll separating force =(1/2) x F(assuming rolls being supported on two bearings)
by using sensors in guide rolls located at the entry and exit side of the mill and the guide roll diameters. The rolling speed is calculated from the rotational speed of the backup roll, using the work roll and backup roll diameters. The roll force is obtained from the pressure gauges of the hydraulic system. Mill current is continuously monitored.
Dec 27, 2018· The rolling force causes the mill frame to stretch so if the ingoing strip becomes thicker then the mill needs to screw down to have the required outgoing thickness.(Feedforw ard control). Obviously there is a time lag between the ingoing measurement and when that thickness reaches the rolls. ... Add to that sensors reading the force in ...
Various rolling drafts were used so that reductions per pass from 2 to 30 percent might be achieved. Temperatures covered the range of 850 to 12OO'C (1560 to 2200OF). Instrumentation A loinch mill was instrumented for the program. The mill has a separating force capacity of MN (550,000 lbs)
Simulations of the hot rolling of U10Mo coupons encapsulated in lowcarbon steel have been conducted following two different schedules. Model predictions of the rollseparation force and rollpack thicknesses at different stages of the rolling process were compared with experimental measurements.
For each series, model, and type of machine, three diameters may be listed: work rolls, backup rolls, and roll journal. Other parameters include maximum separation force at 1000 feet per minute (fpm), total column area, and estimated floor space. Rolling mills include both small, manuallyoperated bench top systems and large, powered machines.
Stanat Model TA215 2Hi/4Hi rolling mill with reversing winders consisting of the following: The existing mill frame will be completely stripped and painted. All bearings and seals will be checked for wear and replaced as needed. A new mill drive with controls will be provided including a 5 .
