Development of a rational roll pass design for a rolling

2013-5-8 · A new technique is developed to analyze the roll pass design of a section rolling mill. Metal forming nonuniformity and efficiency coefficients, which determine the degree of working of a metal microstructure in rolling of section bars, are used as performance criteria. The system of roll passes intended for the production of a round bar 28 mm in diameter is used as an example to analyze

(PDF) A New Method for Roll Pass Design

Roll wear is amongst the key criteria for devising a rational roll pass design. Rolls in a hot mill have to withstand radial loads up to 12 MN and high temperatures in the range of 900 to 1300 oC. In addition to the obvious need for resistance to breakage, there is the continuing component of roll wear that is critical to the economics of

(PDF) Roll Pass design for hot flat rolling of plain

Flat rolling of plates and sheets is essentially a plain-strain compression. f1.2. Roll Pass design for steel The cross sectional area is reduced in each pass and the form and size of the stock gradually approach the desired profile. Here the thickness of the metal being rolled is reduced in each pass by decreasing the distance between the rolls.
