Steel Manufacturing Process Aspects TRIZ Cases

An exhaust gas analyzer monitors unburned fluid concentration to dynamically adjust combustion-supporting fluid supply and reduce peroxidation.

Relocating the rotary joint above the feeder spout outlet reduces seal circumferential speed, enabling high-pressure coolant flow.

A mobile loading plane on a connection conveyor positions inside the furnace to distribute first charge material evenly across the bottom surface.

Segmenting solid-state direct reduced iron melting into two furnaces reduces gangue-induced slag generation, improving molten steel yield from low-grade ore.

Extracting embedded steel from scrap tires allows organic material to act as a reducing agent and slag foaming agent, lowering coke consumption.

Dual AOD converters process pig iron in parallel using autogenous chemical energy from silicon oxidation to produce austenitic and ferritic stainless steel grades.

Accelerometer-based lance vibration analysis detects component frequencies to predict steelmaking slopping conditions in real time.

A measuring device combines electromagnetic and acoustic probes to scan bulk material surfaces in blast furnaces.

Segmented slag separation prevents FeO elution into waste, preserving metallic iron yield and reducing refractory erosion during low-grade ore processing.

A computation section estimates cold iron source melting ratios using real-time molten iron temperature and carbon concentration data.

A steel manufacturing method calculates expected CO2 emissions against predefined targets to optimize raw materials and processes across multiple units.

Estimates supply heat quantity using carried-out sensible heat, carried-in sensible heat, and deadman coke heat content.
