36-inch billet mill the faircrest billet mill is a 36-inch 9144 mm two-high reversing mill that converts blooms to billets and bars ranging from 57 mm to 16-inch rounds or 5-inch 127 mm to 12-inch 304.

Apr 29 2015 2 mill spring- mill spring is defect when the thickness of the rolling sheet is greater than the required thicknessElastic deformation of roll mill equipment or the rolls lead to mill springNormally elastic constant for mills may range from 1 to 4 gnm-1Remedies: use of a stiffer material for making rolls can solve this problem.

It is a special type of four high rolling mill in which each of the two working rolls is backup by two or more of the larger backup rolls for rolling hard in materialsIt may be necessary to employ work rolls of a very small diameter but of considerable lengthIn such cases adequate of the working rolls can be obtained by using a cluster mill.

Billets smaller than blooms and rolled into bars and rods.

The mill is simulated by beams rolls on the infinite elastic half space between rolls and stripThe roll deflection and indentation are calculated using the influence coefficients and boussinesq’s equations respectivelyThe roll contours in the contact zone can be expressed in terms of the influence coefficient and indentation matrices.

The three-roll finishing rolling mill that was installed almost 20 years ago to comply with themTo be able to comply with customers' needs and obtain improvements in productivity and reductions in production cost it was decided to renew the finishing mill with three-roll rolling mills of the latest design.
