Continuous casting plant billet guide track groove rolls - where fatigue failure is avoided by inserting protective material, esp. wire, in base of grooves

摘要

The grooved part is subjected to stresses caused by heat, corrosion, and/or mechanical force, and at least one protective material is located in the base of the grooves to shield the base from heat and corrosion. Material is pref. one or two wires with a dia. slightly smaller than the width of the groove, or a bar with a square cross-section, each side of the square being concave, the bar undergoes elastic deformation when inserted in a groove.
