摘要
本文研究用卧式水平连铸法生产0.06～0.1%Ag-Cu合金线坯,经12个拉伸道次从φ15mm线坯拉伸成小工字型材,具有氧含量为45ppm,导电率(IACS)>97%,布氏硬度H_B=103～107,屈服强度σ_o≥460N/mm^2,软化温度(t℃)>280℃和高温强度(290℃)为27～28N/mm^2,是制造励磁电机中变换器的理想材料。
In this paper, the horizontal conticast is investigated to produce wire blanks of 0.06～0.1% Ag-Cu alloy. After stretched for 12 times, the wire blanks of φ15 mm become small I-sections which prossess an oxygen content of 45 ppm, an electric conductivity (IACS)>97%, a Brinell hardness (H_B) of 103～107, a yield strength (σ_C)≥460 N/mm^2,a softening temperature>280℃ and an elevated temperature (290℃) strength of 27～28 N/mm^2. This material is well suitable to be used in the transverter of the exciting dynamo.
