Abstract

The research of manufacturing parameters influence on the structure and properties of the roll rings (R≤1500 mm) made of the high-strength alloy В95o.ch.-T2 (7475 Т7351-type) was conducted. For this purpose parameters of heat treatment were varied: the soak time during homogenization (24 and 36 hours), the soak time during quench heating (150 and 200 min) and the temperature of the hardening fluid (30 and 60°С). The optimal heat treatment conditions (homogenization and quenching hardening) were determined to provide the required level of properties (σв≥470 MPa, σ0,2≥380 MPa, δ≥6%).
