Russula suministra la cizalla de manivela y la actualización eléctrica

In the spring of 2019, the merchant bar mill at Nucor Steel in Jackson, Mississippi underwent a mechanical and electrical upgrade. Russula supplied a new 40-ton crank shear that was installed at the exit of the roughing mill between stands 7 and 8. The shear is designed for head and tail cutting of rounds, rebar, angles and flats, as well as cobble cutting at speeds between 1-4 m/s. Cutting is performed by two levers, each holding a cutting knife, one on the top and the other on the bottom of the bar. An AC motor drives the crankshafts of the upper and lower knife holders at the same angular velocity, but in opposite directions. The shear features a detachable flywheel for cutting large sections, entry and exit guides and an air operated trough to facilitate scrap collection. It was delivered complete with onboard lubrication, pneumatic and air piping and safety covers.
