REVERSING COLD MILLS - SMSgroup

X-Roll® program offers the right cold mill for you. Ideal for an annual production of 100,000 to 500,000 t are our single-stand reversing mills (RCM). Depending on your product spectrum, they come in four-high or six-high design with CVC ® plus. What makes single-stand reversing mills stand out is their very broad product spectrum.

Metal Bulletin

The rolling equipment can consist of rolls in a single unit, through which steel work pieces are passed and re-passed with the rolling gaps continually reduced (a reversing mill), or comprise a hot rolling line with a succession of roll stands, each set with a narrower gap than the preceding stand to reduce the gauge progressively.

Rolling (metalworking) - Mills - Configurations ...

Configurations. Mills are designed in different types of configurations, with the most basic being a two-high non-reversing, which means there are two rolls that only turn in one direction.The two-high reversing mill has rolls that can rotate in both directions, but the disadvantage is that the rolls must be stopped, reversed, and then brought back up to rolling speed between each pass.

Torpedo Car | Iron to Steel Steel | AMETEK Land

Torpedo Car. Torpedo cars are shaped ladles on rails, used to transfer molten iron from the blast furnace to the steel making facility. These cars are lined with protective refractory bricks which can become worn by continuous use. Temperature scanning of the outer shell detects the development of hot spots caused by internal refractory wear.

A great WordPress.com site. Rockwell scale. The Rockwell scale is a hardness scale based on the indentation hardness of a material. The Rockwell test determines the hardness by measuring the depth of penetration of an indenter under a large load compared to the penetration made by a preload. There are different scales, which are denoted by a single letter, that use different loads or indenters.

Influence of asymmetric structure parameters on rolling ...

Considering the asymmetric structure of a rolling mill system, a chatter model is established by coupling a rolling process model and structure model to describe the asymmetric vibration characteristics. According to this mathematical model, the critical rolling speed is determined by calculating eigenvalues of the characteristic matrix. Model correctness and validity are confirmed by an ...

Kallanish Glossary

Back-up Rolls In a rolling mill, back-up rolls exert force on the two rolls which are actually in contact with the metal being processed (the work rolls). The back-up rolls prevent the work rolls from bending under the forces exerted on them as they "squeeze" the metal passing through the mill into a new profile.
