Cross-wedge rolling lines WRL series

Lines WRL series has one (top) movable die. A slider is installed on rolling-contact bearings with automatic clearance adjustment allowing to minimize friction losses and avoid clearance in guides when the slider is heated during the rolling process.

AMTengineering is a manufacturer of cross-wedge rolling lines and mills of the WRL and WRL TS series with a patented design. The equipment is protected by over 20 patents and inventions.

AMTengineering mills, in contrast to mills of other manufacturers, have a rigid closed structure, designed, depending on the size, for a thrust force from 100 to 1000 tons. programmable flow rate (option) or in manual mode by the operator during routine maintenance. Rolling guides reduce the rolling force by 40% and the drive power of the hydraulic station by 50%, which allows increasing the travel speed of the crosshead (tool drive) up to 180 m / min (in other manufacturers' mills up to 30 m / min). From the operating experience during the operation of the mill in three shifts, the guides without replacement and grinding worked for 12 years. Due to the high rolling speed, the contact time of the hot workpiece with the tool is significantly reduced and, accordingly, the heating of the tool decreases and, as a result, its durability increases (at a high deformation rate, the metal fills the mold much better).

Cross-wedge rolling lines of the WRL series are characterized by the presence of one (top) movable tool. The slider in the machine is installed on roller bearings with automatic clearance sampling, which ensures minimal friction losses and no gaps in the guides when the slider is heated during rolling. Production of parts with a diameter of 6-90 mm.

Advantages of the WRL series cross-wedge rolling line:


At present we have designed and manufactured the following models of the lines series WRL: WRL2510, WRL 2512, WRL3512, WRL4012, WRL6010, WRL6512, WRL8010, WRL8012.

The model name is determined by the maximum diameter of a billet and by the length of a rolling tool.

For example, a line WRL8010 is designed for rolling of billets with maximum diameter of 80 mm and has a length of rolling tool 1000 mm.

Single-piece rolling output of the lines WRL series can reach 600 parts/hour (depending on RF current heating power). The output of pair rolling is doubled.
