Mechanism-controlled thermomechanical treatment of high ...

Mechanism-controlled rolling: The SFE of the Fe–18Mn-0.3C is originally 12 mJ/mm 2 at RT, thus deformation is supposed to be predominated by the TRIP effect. To manipulate the microstructure and introduce twins, rolling can be conducted at an elevated temperature (here 200 °C, SFE 46 mJ/m 2 ).

Tandem strip mill's multi-parameter coupling dynamic ...

The rolling process is determined by the interaction of a number of different movements, during which the relative movement occurs between the vibrating roll system and the rolled piece, and the roll system's vibration interacts with the strip's deformation and rigid movement. So many parameters being involved leads to a complex mechanism of this coupling effect.

The Pulp and Paper Making Processes

A typical layout of a mill using the kraft chemical pulping process is shown in figure 2-1. Mechanical, semichemical, and sulfite pulp mills differ in detail, particularly in wood preparation, fiber separation, and bleaching, but many of the downstream refining, bleaching, and papermaking processes are similar.

Rolling is carryout on a rolling mill and can be performed in two ways; hot and cold process. the rolling mill consists of two more working rollers, supporting rollers, roll stands, drive motor, flywheel, reducing gear, coupling gear etc. The rollers may be plain or grooved depending upon the shape of the product rolled.

Rolling Devices - FUHR

Precision 2-high rolling mill. The 2-high rolling mills of the WSR type differ from the usual 2-high machines available for wire in their higher stiffness and the resultant higher precision of the flat wire produced. Unique to the WSR FUHR rolling mills is the option of oscillating the rolls continuously crosswise to the wire.
