In today’s increasingly popular electric arc furnace steelmaking, graphite electrodes, as key conductive materials, have a direct impact on steelmaking efficiency and product quality. As the most widely used product, RP Graphite Electrode plays an irreplaceable role in small and medium-sized electric arc furnaces, steel mills and alloy smelting fields due to its cost-effective advantage. So, what are the performance specifications of ordinary power graphite electrode? This article will provide you with a detailed explanation.
First, the basic performance specification of common power electrode
Ordinary power graphite electrode is mainly made of high-quality needle coke or petroleum coke as raw material, and re
fined through multiple processes such as batching, pressing, roasting and graphitising. Its main performance parameters include:
Bulk density: ≥1.55 g/cm³
Resistivity: electrode ≤9.0 μΩ-m, Nipple ≤15.0 μΩ-m
Flexural strength: ≥8.0 MPa
Modulus of elasticity: ≤9.3 GPa
Thermal expansion coefficient: ≤2.4×10-⁶ /℃ (at 100~600℃)
Ash content: ≤0.5 per cent
These indexes determine the conductive ability, thermal stability and mechanical strength of the electrode, which is suitable for the operating environment of electric arc furnace with working current density below 17A/cm².
Second, the scope of application and market prospects
Ordinary power electrode is widely used in smelting carbon steel, alloy steel, brass, bronze, silicomanganese alloy, etc. With stable service life and moderate cost, it is the preferred material for many small and medium-sized enterprises in steelmaking. Under the current background that the steel industry is gradually transforming to energy saving and environmental protection, ordinary power graphite electrode still maintains a strong market demand due to its recyclable and pollution-free emission characteristics.
Purchasing suggestions and future trends
When purchasing ordinary power graphite electrodes, customers should pay attention to the consistency, dimensional accuracy and Nipple matching of the products, and at the same time choose manufacturers with reliable quality control system. With the continuous upgrading of graphite electrode production process, the future ordinary power products will achieve further breakthroughs in improving conductivity and reducing loss rate.
