Procedure
Technique
Underlying method (in Part)
Plate type heat exchanger
modification for hot stove
Anti-surge control optimization
for fans
Dual pre-heating (air and gas)
for hot stove
BF gas pneumatic blast
technology
Steel smelting
BOF fume dry dedusting
technology
BOF “negative energy
steelmaking” technology
Recovery of waste heat from
BOF off gas
Recovery of gas and waste heat
from BOF steelmaking
Steam supply from BOF
evaporation cooling system to
vacuum refining furnace
Steel waster vacuum circular
degassing dry (mechanical)
vacuum system application
Optimized EAF power supply
technology
fume dedusting/waste heat
recovery and reuse technology
Polymer rubber injection
technology
Waste heat recovery from
self-disintegrating of slag
Regenerative ladle reheating
technology
High-efficiency continuous
casting technology
Liquid steel passes through
water-cooling crystallizer,
hardens and forms shell and then
is drawn out, and then cut into
billet after cooling and
solidification
Thin slab continuous casting
technology
Steel rolling
Low temperature rolling
