USE OF SHEARS WITH A 'ROLLING CUT'

摘要

This article examines the advantages and disadvantages of using guillotine shears with an inclined top blade for the cross-cutting of flat-rolled products on modem plate mills. It is shown that it is necessary to use shears of an improved design. After shears with a "rolling cut," designed by the All-Russia Scientific Research, Planning, and Design Institute of Metallurgical Machinery (VNIImetmash), were installed in the line of the 2800 plate mill at the Ural Steel combine, the institute conducted studies to optimize the parameters of the cutting operation and developed recommendations for the shears operators on how to adjust the shears to obtain a quality cut edge on the plates.
