To make ferritic stainless steels, one needs iron and chromium, and to make austenitic stainless steels, nickel is added to the mixture. This raw material mixture is melted in an electric arc furnace. The molten metal is refined and decarburised in an Argon-Oxygen Decarburiser AOD vessel by blowing oxygen, argon and nitrogen into the molten steel. The refined stainless steel is processed through a continuous casting machine to produce stainless steel slabs. The slabs can go through a surface grinding process to remove any possible surface defects. This is our first saleable product.

The hot rolling process begins at the reheat furnace where the slabs are heated to between 1 100 and 1 300C, depending on the stainless steel grade. The slabs are then rolled on a reversing four high mill to gauges between 65 and 25mm. Thinner gauges are rolled down further on the Steckel mill. Once the predetermined gauge is reached, the material can either be coiled black coil, also known as hot band, HR or HRA or cut into plate black plate HRA. This is our second range of saleable products.
Cold rolling of the No. 1 coils takes place on one of our four Sendzimer mills Z-mills, which produce smooth, shiny finished, cold rolled stainless steel.
The thickness range of the cold rolled product is between 0,2mm and 6mm.
The material is then annealed softened and pickled and passivated, before it is processed through the skinpass mill, to ensure a smooth surface, known as a 2B finish.
Alternatively, the cold rolled material can be processed to a bright annealed BA finish. This is achieved by annealing in a vertical furnace with an inert atmosphere, to retain the bright surface imparted by the cold rolling process.

Steel comes from iron ore and South Africa is the seventh-largest producer of iron-ore and has also traditionally been the fourth largest exporter worldwide, feeding the fast growing Chinese economy.
A focus on exports has meant that despite the fact that Africa does produce iron ore, it8217s consumption of crude steel has been pegged at a mere 2 percent of global consumption while producing just about the same percentage of crude steel. Steel is essential in both construction and industry as a whole and Africas low consumption is an indicator of her poor economic health.
But what has fueled this growth in the steel industry Indicators point to the global economic crisis which has presented Africa with a silver lining as the last few years of loose monetary policy in the West has made Africa more attractive as an investment destination spurred by attractive return to be made in housing and infrastructure development.
At Metalforming Technology South Africa we manufacture our machinery locally and pride ourselves on our reputation of excellence and professionalism for rollforming machinery in South Africa. We supply and locally manufacture top-of-the-line, quality machines that are designed using international engineering standards for rollforming machinery as well as machinery for steel used in profiling.
Three rolling processes. We differentiate three rolling methods conventional hot rolling at high forming temperatures, normalizing rolling and thermomechanical rolling. The pre-material is the same for each of the rolling methods a homogeneously heated slab from the heating furnace with a relatively coarse-grained microstructure.
