RP Graphite Electrode Overview

Diameters 8-24 inch

RP GRAPHITE ELECTRODE

Regular power(RP) graphite electrode, which allows through the current density lower than 17A / cm2, RP graphite electrode is mainly used for ordinary power electric furnace in steelmaking,refining silicon, refining yellow phosphorus industries.

  • Low Consumption
  • Good Linear Expansion
RP-Graphite-Electrode

Description

RP electrode uses ordinary grade petroleum coke production, the raw material requirements are not high, graphitization temperature is low, so its resistivity is high, linear expansion coefficient is large, thermal shock resistance is poor, the allowable current is low, suitable for ordinary steelmaking. RP is suitable for common power arc furnace of 300Kv.A/t per ton furnace melting.

All the raw materials are mixed and then molded. Heat treatment is then applied in the baking and graphitization process to form the finished product.

We are an industry leader in the production, sales, export and supply of graphite electrodes for a wide range of applications. Our products have excellent electrical conductivity, and perform well in harsh smelting conditions.

As a manufacturer, we also provide UHP grade graphite electrodes and HP grade graphite electrodes for ultra high power or high power electric arc furnaces. In addition to being used in arc furnaces, graphite electrodes are also widely used in submerged arc furnaces and Ladle furnaces

RP Graphite Electrode Features

  • High current carrying capacity
