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. Typical Application Data: Material and cylinder speeds: typically up to 2,000 m / min.

Even if the design speed of the mills may be higher, these mills run at rolling speeds ranging in most cases 12 to 15 meters per second. The reason for such low speeds is the fact that operation is sensitive at small sizes and mill setting requires fine accuracy.

Cold Rolling Mills The evolution of rolling mills has accelerated as the speed of processors and digital controls have grown by orders of magnitude. The capital cost in a rolling mill is substantial and investors understand that in order to achieve the maximum ROI and shortest payback time, the mill needs to produce high quality sheet at the ...

4.2.3.1.1 Roll Mills. The roll mill is the simplest batch mixing equipment. The principal design consists of two horizontal rolls, usually of equal size, arranged side by side and rotating toward each other at different speeds. The ratio of the peripheral speeds of the rolls, known as friction ratio, ranges from 1 to 2 but is usually around 1.2.

Rolling mills. Rolling mill consists of rolls, bearings, structure, or housing for rigidly supporting these parts, power drive, power transmission system, speed control, roll gap adjusting set up, etc. The force for rolling generally is very high. The power requirements are very high. Hence initial capital investment is high.

The elastic curve of the mill is not exactly a straight line, at the beginning of the elastic curve is not a straight line, but a small section of the curve. This is due to the existence of a certain gap between the components of the mill and the contact is not uniform.

Temperature monitoring and control are critical factors in Hot Rolling Mills to assure desired product properties, ensure quality product, improve line speed and process control. There are a number of interferences that can affect the steel infrared temperature sensor reading at every point along the hot rolling mill. These include water, steam ...

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 anti-clockwise) and so spaced that the distance between them is somewhat less than the ...

A tandem rolling mill is a rolling mill with two or more close-coupled stands, each of which is setup for rolling using the spring curve and the compressive curve of the metal so that both the rolling force and the exit thickness of each stand are determined.. The main advantages of a tandem mill are: only one single pass is required which saves time and increases production; …

The mill stretch compensation and other disturbances during the rolling process are compensated and a rolling speed dependent, adaptive PI controller is developed to accomplish fine thickness co...

According to the condition of seamless steel tube stretch reducing mill (rolling force, speed and pipe diameter), the combined hard alloy stretch reducing roll is used to obtain high cost performance. CONG GUI IMPROVE PERFORMANCES CONG GUI becomes the obvious choice to replace conventional grades. CONG GUI is a highly alloyed material developed ...

Bar Rolling Mill Annual Capacity: 30,0000 ∼ 50,0000 TPY. The billet is 150mm *150mm *8000mm continuous casting billet with a billet weight of 1404 kg. Products: hot rolled round steel, ribbed steel bar. Rolling Speed: maximum finishing speed of 16 m/s. Specification: round steel ∅14mm~∅40mm, ribbed steel ∅12mm~∅40mm.

Except for bloom rolling and slab rolling stands, the power from motor goes to gear box for speed reduction and then to pinion box for distributing the power between two rolls (Fig.7.14). In slab rolling and bloom rolling mills, no gear box is used, motors are connected directly to rolls through universal couplings.

The two-high rolling mill consists of a two-high stand with two horizontal rolls, placed exactly one over the other. In this type of mill, one or both the rollers are adjustable. In its operation, the metal is passed between the two rollers rotating at the same speed but in opposite direction. They typically have larger diameter rolls that are ...
