Gross yield improvement is one of the major objectives in Hot Strip Mill (HSM) operations because yield loss directly affects production cost and profitability. In HSM#3, significant losses occur due to crop end cutting, sampling, scale formation, and salvaging losses. This review paper discusses the major causes of yield loss and the techniques used to reduce them. The study focuses on optimization of crop end cuts, reduction of sampling losses, and minimization of salvaging losses through improved process control, accurate strip measurement, and defect reduction techniques. Existing methods such as Laser Doppler Velocity Meter (LDVM), encoders, and Hot Metal Detectors (HMDs) are reviewed along with their limitations. The paper concludes that proper crop optimization, improved measurement systems, and better rolling process control can significantly improve gross yield and productivity in hot strip mills.
