Carbon Electrode Paste

Carbon Electrode Paste / Soderberg Electrode Paste Quality Specification: At the customers end the paste is fed in the upper part of the electrode it softens and melts forming the shape of the electrode casting. Flow ability of carbon electrode paste is essential for proper operation of electrode. It is important that the paste flows at a reasonable temperature and fills the casting of the electrode, maintaining a consistent mixture of components. The paste then gets baked to a solid mass as it moves down and is capable of passing the required current to the furnace charge. The plasticity of paste , the measure of its flow ability is controlled in the mixer by adjusting the binder content or percentage of coke fines. The lower baked part of the electrode is the final electrode product. The physical properties of this paste are of vital importance to ensure proper electrode operation without breakages. Green paste: A) Plasticity : 30-35%, 35-40% (or as per buyers requirement ) B) V.M. : 12-14% C) ash : 0.5% max D) f.C. : 86% min E) Apparent density : 1.58gm/ccmin. Baked paste : A) f.C. : 99% min B) porosity : 22-24% C) Apparent density : 1.36gm/cc min D) ccs : 250kg/cm2 min E) electrical resistivity : 70-90 micro ohm meter. Size : mould of 24ö dia & 4ö thick (wt. Approx 46kg. To 48 kg. Per block). 24" dia & 4"thick approx 46 to 48 per block. Size in briquette form or as per buyers requirement can also be made available.
