Ultra High Power UHP 650mm Furnace Graphite Electrode For Smelting Steel

Short Description:

UHP graphite electrode is a high-quality product known for its superior performance, low resistivity, and large current density. This electrode is made with a combination of high-quality petroleum coke, needle coke, and coal asphalt to offer maximum benefits. It is a step above the HP and RP electrodes in terms of performance and has proved to be a reliable and efficient conductor of electricity.

Product Feature

Ultra high power(UHP) graphite electrode has high thermal conductivity and is very resistant to heat and impact.It is mainly used for ultra high power electric arc furnace(EAC). The current density greater more than 25A/cm2. The main diameter is 300-700mm, which improve production efficiency and reduces costs.

UHP is a suitable and excellent choice for ultra-high power electric arc furnace of 500~1200Kv.A/t per ton.UHP graphite electrode physical and chemical index is better than that of the RP, HP graphite electrode.It can shorten the steel making time, increase production efficiency.

Product Application

The UHP graphite electrode's performance is not only limited to the steel industry. It has a wide range of applications, including electric arc furnace smelting, ore smelting, calcium carbide smelting, and aluminum smelting. Its versatility is a testament to its superior performance and its potential to revolutionize not only the steel industry but other industries as well.
