Manufacturing Converters TRIZ Cases

Negative-pressure coolant flow cools furnace sections below the taphole, preventing fluid ingress, hot spots, cracks, and explosion risk.

Pre-dried iron sludge is granulated below 4 mm and dried to 3% moisture, enabling low-dust pneumatic injection into a cyclone ironmaking vessel.

A staged converter, LF, and RH route cuts phosphorus from ultra-high phosphorus molten iron while lowering slag, energy use, and cost.

A higher-melting casing around core-embedded conduits prevents coolant leakage while reducing pressure loss, cost, and thermal stress in furnaces.

Controlled casting, rolling, normalizing, and tempering produce mirror mold steel plate with uniform 38-42 HRC hardness and lower cost.

Sequential cooling, dust collection, and SCR in the primary fume line stabilize gas conditions and cut NOx in electric arc furnace plants.

Controlled Cr-Ni-Mo-Ti alloy ratios and cooling create fasteners that keep very high strength while resisting delayed fracture at notch stresses.

Controlled Al-Nb-Cr-Mo alloying and refining create spring steel wire that resists corrosion pits and hydrogen cracking in humid salt exposure.

Controlled alkali addition timing changes precipitate composition, cutting silicon and iron impurities in recovered phosphoric acid and target phosphates.

Dynamic oxygen, carbon dioxide, and lime powder control stabilizes nozzle mushroom head size to limit erosion, blockage, and heat loss.

Single-camera image analysis measures slag flow width to estimate discharge amount more accurately than weighing or geometry-based methods.

Controlled alloy content and rolling-cooling create polar marine steel with low-temperature toughness, weldability, and lower production cost.
