Cold Product Down-Cut Shears
Robert Bennett, Danieli Corp.
Cold product shears are critical pieces of equipment in a bar mill. Located just downstream of the cooling bed, these shears take the cooling bed material cut to multiples of the customers length and cut it to the proper ordered length. These “cut” lengths must arrive at the customer within length tolerance and exhibiting acceptable sheared ends. Understanding these shears and how to maintain them is a very important operator and maintenance function.
