TACKLING THE LAST EFFICIENCY FRONTIER IN STEEL MANUFACTURINGTHROUGH ARTIFICIAL INTELLIGENCE

SST PRODUCT OVERVIEW

Smart Steel Technologies supplies ready-to-use AI software products for processoptimization in steel plants. These productsserve to optimize energy consumption andCO2 emissions, improve product quality andreduce costs. Smart Steel Technologies’product line focuses on temperature optimi-zation for the liquid phase, reduction ofcasting and rolling defects, and the stabili-zation of surface inspection. As a result ofthe increased efficiency, steelmakers cansave significantly on production costs andreduce their emissions.

ArcelorMittal, the world’s leading steel-maker, is an official reference customer ofSmart Steel Technologies.

At multiple integrated and EAF steel plants,SST’s software is used successfully inproduction to optimize quality and to reducecosts.

SST TEMPERATURE OPTIMIZATION AI

SST Temperature Optimization AI provideslive temperature guidance for every heat andfor each liquid phase process. Throughprecise modeling of each individual processas well as by cross-process modeling, SSTTemperature Optimization AI increases pre-cision in temperature guidance and provideshigher process stability and reduced energycosts.

Solutions provided at critical points in liquidphase processes:

§ BOF in-blow point§ EAF flat bath phase§ LF, RH§ Continuous casting

EBITDA IMPACT: EUR 5 MILLION P.A. FOR PRODUCTION VOLUME OF 5 MILLION TONS P.A.

FULL TEMPERATURE GUIDANCE FROM TAPPING TO CASTING

SST CASTING OPTIMIZATION AI

SST Casting Optimization AI leads to per-manently increased casting quality withoutinstallation of new equipment. Defect ratesand downgrading costs are reduced. Yield isimproved, in particular, for high quality steelgrades. Energy is saved through increasedhot charging.

SST provides one software component forautomated optimization of each casting se-quence before start of casting and a secondsoftware component for live optimizationduring casting. The solution uses all avail-able process and quality data and has beendesigned by continuous casting experts.

EBITDA IMPACT: EUR 6-7 MILLION P.A. FOR PRODUCTION VOLUME OF 5 MILLION TONS P.A.

PERMANENTLY REDUCED RATE OF CASTING DEFECTS WITHOUT INSTALLATION OF NEW EQUIPMENT

SST ROLLING OPTIMIZATION AI

SST Rolling Optimization AI leads to apermanently increased quality of rolled pro-duct without installation of new equipment.Geometry tolerances, defects caused by therolling process and unwanted rolling inter-ruptions are reduced. All systems are con-tinuously monitored for further potential forrolling optimization.

SST’s software components enable liveoptimization of the rolling process. This in-cludes predictions of quality deviations and

interruptions of the rolling process. Thesolution enables the steelmaker to react inreal-time to minimize rolling defects andundesired interruptions.

EBITDA IMPACT: EUR 6 MILLION P.A. FOR PRODUCTION VOLUME OF 5 MILLION TONS P.A.

STATE OF THE ART QUALITY AND PROCESS STABILITY FOR ROLLING MILLS

SST SURFACE INSPECTION AI

ACCURATE DEEP LEARNING CLASSIFIERS FOR HSM, PL, CGL

Deep CNN classifiers specifically designed for hot strip, pickled strip and galvanized stripdwarf conventional surface inspection systems when it comes to accurate classification ofcomplex surface defects, e.g., slivers. The full package includes tools for defect imagesearch, quick training set optimization, and more.

CROSS-PROCESS SOLUTION

All surface defects are mapped into a central coordinate system and are displayed on SST’sCentralized Coil Map. From the hot strip mill down to all galvanizing lines, the softwareprocesses each coiling / uncoiling operation, cutting, cropping, welding, and trimming stepsto match defects to exact positions across all production steps.
