“…Genuine prediction of the required fuel input, the most important process parameter for the ore, is, therefore, only possible if a precise forecast can be made of the chemical utilisation of the CO from the coke or -which amounts to the same thing -of the degree of indirect reduction with each individual ore, which substantially affects the heat requirement. For example, HORIE 753 ) obtained the following standard deviations in Si-eontents in superlatiw furnace driving conditions: without auto-control: ± 0 .12%, with auto-control: ±O.1O%. They certainly cannot be considered as ore-dependent constants but depend extremely closely on 362.…”

The steel industry pioneered the use of computers for process control. By the mid 1960s, almost a fifth of the world's process control computers were installed in the steel industry. The present paper documents the development of direct digital control with emphasis on hot strip mill control, notably the installation at Llanwern using a GE 412 computer. Early applications of computers in areas such as electric arc furnace control and order handling are identified. Archive sources, government documents, interviews, correspondence and technical papers show the leading role of steel in developing online control. Marked differences in adoption rates are identified. Twothirds of the early steel installations were in the USA. Britain and Italy were also early adopters.Jones & Laughlin and Inland of the USA, the Steel Company of Wales and Italsider were among the leading innovators.
