Modifying the Silicon, Manganese Alloy Formula in Steel Factories in Sudan

Steel industry is one of important sector which contributes in the development in steel sector. This reflects positively in national income the objective of this paper was to modify routinely used formula in steel bar industry, this was applied by adding (silicon and manganese) alloy for bar steel manufacturing, considering all the variation that effect on steel specification to render it more flexible with high quality and less time for treatment. Three hundred and three reports (have specifications of melting) were taken to study the relationship among all the elements in the report to determine the relation between the elements and the new formula was used in the production line of steel bar. The analysis of result by SPSS showed that newly formula used to produce steel bar has seven variations better than routinely used which had two variations, newly obtained formula had been tested three times in steel bar production process, the result was acceptable compared with routinely used in the factory. This new formula due to its reduced cost of used amounted (silicon and manganese) alloy, less time for treatment and with high quality, is highly recommended to apply in steel bar production.
