Rolling Mill Process - RMT Tools

As the transfer bar exits the last roughing mill stand, the thickness of the leading edge of the bar is estimated. Similarly, a pyrometer measures the temperature profile of the bar from head to tail. Depending on the gauge, width, and grade of the product to be rolled. This data is collected in anticipation of finish rolling.

Understanding Rolling Process in Long Product Rolling Mill

Using the working diameter of the rolls, the roll rpm (revolutions per minute) is matched to the bar speed through the mill. As the rolls wear and the spread of the bar in the pass changes, the rpm of the stands need to be adjusted as the bar area changes. Most modern control systems modify the R-Factor as this occurs.

Rolling of Steel in a Modern Long Product Rolling Mill

As the bar progresses through a continuous mill where the bar is rolled in multiple stands simultaneously, the stand speed must be controlled to ensure tension free rolling. The main methods of controlling the tension in the mill is with a tension free rolling speed control system and manually monitoring the current drawn by each motor as the bar proceeds through the mill. A looper table can

Rolling Mills | Industrial Efficiency Technology & Measures

In rolling mills, intermediate steel products are given their final shape and dimension in a series of shaping and finishing operations. Most of the slabs are heated in reheating furnaces and rolled into final shape in hot– or cold–rolling or finishing mills. While some products (e.g. reinforcement bars, steel plates) only require hot-rolling, some others may require both hot– and cold–rolling (steel for cars

Effect of pass schedule and groove design on the metal

The deformation behaviour of a hot rolled micro-alloyed steel bar of grade 38MnVS6 was examined using an FEM model during the initial passes in a blooming mill, as a function of three different pass schedules, roll groove depth, collar taper angle and corner radius. The simulations predicted the effective strain penetration, load, torque, fish tail billet end shapes, and metal flow behaviour at a chosen

To develop a power curve for rounds, we know the area of the bar as it progresses from the mill, from either the pass schedule, mill measurements, or samples. The power is read from the volts and amps at the motor. The production rate is calculated from the motor RPM. At each stand we then have the power, elongation, and production rate.
