Development and Production of 4Cr5Mo2V Large Die Steel 640 mm x 1100 mm Forged Bloom for Automobile Die Casting
生产的640 mm×1 100 mm 4Cr5Mo2V大型模具钢的非金属夹杂物(≤0.5级)、显微组织、横向冲击功(KV2 25~31 J)
均高于北美压铸协会NADCA#207-2018标准高级钢质量水平
等向性达到0.95。
Abstract
By using combination teachnology of 20 t EAF-LF-VD
20 t argon protection ESR unit remelting
1 250 ~1 280 ℃ high temperature homogenization treatment
60 MN oil pressure quick forging machine multiple forging and 1 000 〜1 050 ℃ high temperature solution treatment process
the inclusion(≤0.5 rating)
structure and lateral impact energy (KV2 25 〜31 J) of produced 640 mm x 1 100 mm 4Cr5Mo2V heavy die steel are higher than the requirement in standard NADCA#207-2018 for advanced steel leave
