International Publications of Metal Pass
Introduction: Over 30 papers on steel automation especially on the Level 2
improvement and further development were written in the period from
mid-February to mid-March and were published.

Li, B.: Evaluation of various procedures in
predicting of spread during wire rod rolling.
Abstract/Contents: Around ten frequently used procedures in predicting spread
(width change) during steel wire rod rolling were introduced. Comparisons with
the lab mill data and plant measurement were carried out for model
verification.
Total pages: 100

Li, B.: Calculation of roll separating force
during hot rolling.
Abstract/Contents: A unique form for prediction of roll separating force has
been developed for various rolling processes (flat rolling and shape
rolling in various pass sequences). This model describes three primary
parameters: Mean Flow Stress, Shape Factor and Projective Contact Area.

Li, B.: Heat transfer and temperature determination
during hot rolling of steel wire rod.
Abstract/Contents: Major heat transfer forms in every stage of steel hot
rolling were discussed, and on this basis the procedure to determine
temperature in each rolling stage is proposed.
Total pages: 6

Li, B.: Procedure to calculate roll separating force and rolling
torque for high speed wire rod rolling.
Abstract/Contents: A procedure to calculate roll separating force and rolling
torque for high speed wire rod rolling is introduced. This includes models for
flow stress, roll separating force and torque. The case covers the rolling
speed up to over 100 m/s.
Total pages: 10

Li, B.: Theory and Practice of Modern Roll
Pass Design.
Abstract/Contents: This report provides detailed coverage on the roll pass
design theory and modern pass practice. In particular, it summarizes the
research results in recent years on the roll pass design.
Total pages: 100
