The production flow sheet for stainless steels steelmaking at Taishan Steel Works is 60 t EAF-GOR bottom blowing converter refining-160 mm x 1600 mm slab casting process. With using Gleeble-1500D thermal simulation testing machine
the high temperature properties of casting slab of austenite stainless steel 201 ( 6.54Mn-16.71Cr-3.62Ni) and steel J4 (8.93Mn-14.84Cr-l.08Ni-l.25Cu)
ferrite stainless steel 430 ( 16.29Cr) and martensite stainless steel 410S (13.5Cr) have been tested and studied. Results show that the Ⅲ brittle temperature region of each stainless steel is respectively steel 201-665 ~990 ℃,steel J4- 600~950 ℃ steel 430- 600~700 ℃ and steel 410S-720~930 ℃ ; It is available for steel 201 and J4 to use weaker secondary cooling and to straighten respectively at ≥1010 ℃ and ≥995 ℃
for steel 430 to use stronger secondary cooling and to straighten at 900~950 °C
and for steel 410S to use weaker secondary cooling and to straighten at ≥ 980 °C.
