Hot Rolling Mill Hydraulic Gap Control (HGC) thickness
Roll bending is not directly linked to thickness control, but usually this control is incorporated in the same hardware, together with AGC. Work roll bending forces are applied, using hydraulic cylinders, to the work roll shafts loed at both roll ends. As a simplified explanation, positive or crownin

Understanding Rolling Process in Long Product Rolling Mill
Nov 27, 2015 · Understanding Rolling Process in Long Product Rolling Mill Steel rolling consists of passing the material, usually termed as rolling stock, between two rolls driven at the same peripheral speed in opposite directions (i.e. one clockwise and the second anticlockwise) and so spaced that the distance between them is somewhat less than the
Rule based DFM analysis for forging Wikipedia
Rule based DFM analysis for forging.Forging is the controlled deformation of metal into a specific shape by compressive forces. The forging process goes back to 8000 B.C. and evolved from the manual art of simple blacksmithing. Then as now, a series of compressive hammer blows performs the shaping or forging of the part.
Suppression of Switched Reluctance Motor Vibration of In
Switched reluctance motor (SRM) has got great attention in inwheel motor electric vehicle (IWMEV), but SRM vertical force, the vertical component of SRM unbalanced radial force, yields SRM vertical vibration and does harm to dynamic performance of IWMEV. In order to reduce the SRM vertical vibration, electromagnetic active suspension and a linear quadratic Gaussian (LQG) controller were

Forging vs. Casting: Which is better? Columbus McKinnon Blog
Aug 06, 2013 · Forging and casting are two very different manufacturing methods. When something is cast the material is heated above its melting temperature and poured into a mold where it solidifies. When something is forged it is physically forced into shape while remaining in a solid state – although it is frequently heated.
US5347837A Method of rolling using bendable sleeved roll
A method of rolling an elongated workpiece in the form of a sheet or strip and of reducing edge drop during rolling comprising passing the workpiece through at least one pair of opposed work rolls which comprise an arbor and a hollow sleeve shrinkfitted over the arbor and having end portions defining, between the arbor and sleeve, a cavity providing a selfcompensating flexible roll end
Forging Wikipedia
Forging is one of the oldest known metalworking processes. Traditionally, forging was performed by a smith using hammer and anvil, though introducing water power to the production and working of iron in the 12th century allowed the use of large trip hammers or power hammers that increased the amount and size of iron that could be produced and forged. . The smithy or forge has evolved over
Grinding wheel selection, static balance and dressing method
Jul 30, 2019 · Grinding wheels for grinding cold rolls are generally selected with soft grinding wheels. Particle size of the grinding wheels should be between 80 mesh and 120 mesh. The grinding wheel should be carefully and repeatedly statically balanced before use.

Seamless steel pipe produces eccentricity (uneven
Mar 27, 2019 · This method can also be used to study the uneven wall thickness of other steel tube production units. The picture above shows the seamless steel pipe perforation site. The eccentricity of many steel pipes is generated at this time, so it is very important to strictly control this perforation.
Forgings Where, Why, How? Forging Industry Association
It is not a special technology, but a refinement of existing techniques to a point where the forged part can be used with little or no subsequent machining. Improvements cover not only the forging method itself but also preheating, descaling, lubriion, and temperature control practices.
Motion Basics Terminology & Standards Newport Corporation
Motion Control Coordinate System: In free space, an object is considered to have six degrees of freedom: three linear, along the x, y, and zaxes and three rotational around those (see Figure 1). All motions described here follow the righthand coordinate system convention. The crossproduct of +X and +Y axes (pointer and middle fingers) is the +Z axis (thumb).
hot rolling mill roll eccentricity
The roll eccentricity in a rolling mill may define the limit of achievable thickness tolerances and thus is subject of interest for the automation equipment in hot rolling mills as well as in cold rolling mills. Today''s demand on thickness tolerances less than 0.8% require efficient methods for roll eccentricity identifiion and compensation.
