1 NETANYA PLASMATEC LTD Confidential Plasma Treatment Casting (PTC)

2 NETANYA PLASMATEC LTD Confidential PTCs Competitive Advantages for high grade steel ingot Production cost reduction by 10%-20% Ingot casting yield increase from 80% to 90% Segregation reduction Grain refinement Mechanical properties improvement Enables ingots casting with larger dimensions Shrinkage and porosity elimination Environmental emission reduction by 15%

3 NETANYA PLASMATEC LTD Confidential The Effects of PTC Process Replacing hot isolation- feeding the liquid metal with a concentrated energy Reducing heat gradient - intensive heat exchange in liquid metal Stirring liquid metal while solidification- through multi- dimension electric and electromagnetic fields Producing additional pressure in risers - reducing risers height by exchanging potential energy with kinetic energy

4 NETANYA PLASMATEC LTD Confidential The PTC process applies plasma arc during metals and metal alloys solidification process. The rotating plasma arc moves along a prescribed path, defined by a special electrode. The PTC Process Confidential
