Carbon raiser/ carbon additive is also known as gas calcined anthracite coal (GCA) or calcined anthracite coal.
ECA (ELECTRICALLY CALCINED ANTHRACITE)
Calcined Petroleum Coke (CPC) is used extensively as Anode in Alumina Smelters, as Soderberg's Electrode for Ferroalloy Industries, and in the manufacturing of Graphite/ Graphite Electrodes, and Thermal Paste for Ferro Alloys & allied industries in Submerged Arc Furnaces.
CPC is also used in various Steel Industries for - Melting of Steel , Recurburisation and for making Special Steels & Alloys.
High purity graphitized petroleum coke is made from high quality petroleum coke under a temperature of 2500 - 3000°C.
Perlite is a special volcanic glassy rock type that is created by microscopic lamellar structures or fractures of a protrusion, which is a result of cooling in petrography. Perlite is also the name given to natural volcanic rock formations of silica basis.
Chromite is an Iron chromium oxide found naturally in the earth crust. It is by far the most industrially important mineral for the production of metallic chromium, used in the production of Stainless and Tool Steel.
