Cutting rolled product into required lengths as it leaves a rolling

Abstract

Abstract Stock iron is cut into required lengths in a two cut operation, a first cut being made before the iron is cooled. Each length (L) to be divided into x lengths (lK) and a residual length (lR) and a second cut is made in one or more stages to give final required lengths (lHi). Before cutting, a histograph of (L) is made for each product dimension and type of steel i.e. the % probability (p dL) of obtaining lengths between (L) and (L+dL) from the rolled product, and the % (ai) of LHi) in the total number of products ordered, these data are used in a calculator to give the total product of the cutting (eta w) from the equation The product of cutting (eta w) being defined as the yield of the metal cut into required lengths.
