Method for in-situ regrinding of the rolls of hot strip mills

摘要

Working process for regrinding the rolls in hot rolled structures behind a two-rod thin slab casting apparatus comprises comparing the wear, produced on the rolled structure during alternating rolling of two different band widths, on the rolling balls by subsequent roughening of both the rolling ball regions covered by the wide strips, and blackening of the middle rolling ball region covered by narrow strips with at least one grinding tool.
