component in this process is coking coal mainly imported into South Africa which is used to produce coke needed both as the chemical reductant and as the source of energy in the process An alternate steelmaking technology also used in South Africa is the electric arc furnace EAF route Although this process uses small quantities of iron ore Today machining of screws has been superseded by thread rolling In American William Keane developed the thread rolling process but at the time it had little success The iron metal that was used to create the thread rolled screws was too low grade and had the tendency to split during the die cutting process
