Transalloys produces Sillicomanganese for world markets. The plant is situated 14 km West of eMalahleni and approximately 90 Km East of Pretoria.
Production capacity is 150 000 - 155 000 tonnes of Manganese ferroalloys, being silicomanganese, high carbon ferromanganese and medium carbon ferromanganese.
The standard grade Silicomanganese contains 15.5 to 16.5% of silicon, 65 to 67% of manganese and a maximum of 2% carbon. SiMn is used, inter alia as a grain refiner and for de-oxidation in the steel manufacturing process.
Our Vision is to become a benchmark in the Manganese alloy industry through our people, flexibility and pursuing results. We aim to achieve this by adhering to our values of integrity, excellence, teamwork and commitment.
Transalloys utilises 5 submerged arc furnaces to produce SiMn.
The submerged arc furnaces comprise of two 48 MVA semi-closed furnaces and three 18 MVA open furnaces. Raw materials are fed from a common raw material handling system into three sets of day bins, from where the individual furnace recipes are batched and conveyed into the furnace bins.
The furnaces are tapped at regular intervals and the alloy is separated from the slag before being cast into layer casting beds. After a cooling down period of ± 3 days, the material is removed from the casting beds and fed into a crushing and screening plant. The different size fractions are separated and stockpiled or dispatched to ports for export, or collected by local customers.
At Transalloys we are aware that our activities could have an impact on the environment. In this regard we aim to comply with applicable legal requirements. In addition, all process changes, upgrades and refurbishments are carried out with consideration of the impact of the changes, in order to mitigate or eliminate the environmental impact. Our comprehensive environmental management plant guides future capital expenditure in order to ensure that our impact on the environment continues to reduce.
Transalloys is compliant to the ISO 9001, 17025, 45001 and 14001 international Standards. Transalloys is also the owner of one of the first CDM (Carbon Reduction Mechanism) projects in South Africa. During the past 5 years, huge improvements in efficiencies gave rise to a considerable reduction in carbon emissions per tonne of product produced.
