The Melt Conditioned Twin Roll Casting (MC-TRC) Process

The melt conditioned twin roll casting process is a relatively new technology which aims to correct some of the disadvantages of the TRC process namely the reduced strength due to coarse grain structures. The proceeding MCAST process provides conditioning in the melt stage which ultimately generates materials with excellent grain size after the rolling process. Continue reading

Hollow Ingot Casting

Hollow ingot casting is a well-established casting technology which is used by many well-known manufacturers the world over to produce lighter good quality ingots for a range of applications. Some key advantages of hollow ingot castings include shortened forging times and subsequent yield increase and obvious savings in materials and finished product weight. Continue reading

Compacted Graphite Iron: Part Two

Compacted graphite iron (CGI) along with lamellar graphite iron and spheroidal graphite iron define the three main classes of cast iron according to morphology.
An important measure for assessing the application of CGI is the machinability levels and through specific studies it was concluded that CGI is much more difficult to machine than standard grey cast irons. Continue reading

Boron Grain Refinement: Part One

Grain refinement is an established technique which basically reduces the grain size of the material with the direct intention to improve its finished properties or characteristics.
The addition of boron specifically in aluminum castings, which are well known for their poor mechanical properties, can improve these characteristics to expand the potential use of the castings to a multitude of other applications. Continue reading

Expert Furnace System Optimization Process (EFSOP)

In typical EAF systems around 45% of input energy is lost through slag or off gas, the latter representing 70% of the complete loss of input energy. The expert furnace system optimization process attempts to tackle this issue by allowing a real time assessment of the energy lost through off gas and to allow plants to react quickly and therefore keep this loss to a minimum.
