Q.B4.A 300 mm wide and 20 mm thick strip of Steel is fed through a rolling mill with twopowered rolls of radius 200 mm. The single pass rolling operation reduces thethickness to 17 mm with rollers operating at 40 RPM. The flow strength coefficient is375 MPa for the metal and strain hardening exponent is 0.11. The coefficient offriction between the strip and the rollers is 0.1. Use the information to answer thefollowing:a.) Is the rolling operation possible for the given draft?b.) What is the roll force required?c.) What is the roll torque required?d.) What is the input power required if the system is 80% efficient?e.) In a forging operation flash formation is common and useful at times. Using adrawing describe a flash formation in forging and why is this useful for the operation?

3- A planned extrusion operation involves cold-rolled steel at 1000° C to diameter of 75 mnm with length 65 mm and a final length 70 mm Two presses, one with capacity (extrusion force) of 30 MiN and the other with a capacity (extrusion force) of 20 MN, are available for the operation. Is the smaller press sufficient for this operation? K"=35x10*3 N [Hint: Calculate the extrusion force and compare it to the available two presses!
A hot/cold rolling setup is shown right. The operation first hot rolls a 3/8” thick plate, 12” wide (w), of6061 Aluminum, to an intermediate thickness, then finally through cold rolling, down to 1/4” thick plate.The friction factor μ is assumed to be constant at 0.15 for the hot roll, 0.12 for the cold rolling stage. Thefirst set of rolls operate at 50 RPM. Also ignore any width increase during rolling. CW=13% or .13 What is the plate thickness (mm) prior to the last rolls, t1, if the last set of rollers perform cold work reduction listed below at .13 or 13% Note that 9.52 mm is equal to 3/8 of an inch.

7. A strip of annealed low-carbon steel (K = 528 MPa, n = 0.25) is rolled from its initial dimensions (210 mm wide and 13 mm thick) to a thickness of 7 mm. The rollers have a radius of 250 mm, the roller rotates at 200 rpm, and u = 0.1. Compare this high frictional force and power with the low frictional (u = 0) forces and power. a. Estimate the roll force and power required for this process.
Q1/ A two-high rolling mill is used to reduce plate that is 450 mm wide and 45 mm thick in a single pass to a thickness of 30 mm. The roll has a radius = 500 mm, and its speed = 25 m/min.

cylindrical roller of radius R1 = 1in. and length L = 1.5 in. is subjected to a load F = 1000 lb as it runs on a parallel roller with radius R2 = 1 in. Both rollers are made of AISI 4340 steel HB 320-340 (E = 30 Mpsi, ν = 0.28). The rollers are in combined rolling with 9% sliding. The coefficient of friction is µ = 0.33. Estimate the lifetime of the rollers.
Given: Flat rolled sheets are produced in wide rolling mills, but many products are manufactured from strip stock. The below figure is a free-body diagram of a shaft for a short slitting line where a single blade is placed in the center of the shaft and a motor drives the shaft through a pulley at the far right end. Find: The shaft diameter If the maximum shear stress is 40 MPa and the largest gage sheet causes a blade force of 2000 N,
