T-SECTION HOT ROLLING METHOD Russian patent published in 1995 - IPC

Abstract RU 2030933 C1

FIELD: working of metal. SUBSTANCE: method involves rolling with looping in alternation with tension of strip plate between stands, with looping of plate being effectuated after pass, where wall is predominantly reduced, and tension of strip plate being effectuated after pass, where strip part of section is predominantly reduced. Strip plate wall is settled down in one of shaping passes by jamming it for 15-25% of its height till boss is formed at base side. Base is flattened in subsequent pass. Prior to feeding at base side. Base is flattened in subsequent pass. Prior to feeding strip plate to finishing pass, temperature over cross-section is equalized by local cooling. EFFECT: increased efficiency and high quality of section. 12 dwg, 2 tbl
