RP graphite electrode supplier

RP Graphite Electrode

Regular power graphite electrodes are made from regular petroleum coke at low graphitization temperatures. Compared to the high-power graphite electrode, the currents and temperature it can endure are lower. The resistance is higher, the linear expansion coefficient is large, and the thermal shock resistance is lower. It is mainly used in refining ordinary steel, silicon, and yellow phosphorus.

Advantages of AGRM graphite electrodes

Save costs

The graphite electrode helps save costs. It consumes less power and saves electricity consumption per unit of steelmaking.

Improve efficiency

The high electrical conductivity means high current efficiency which speeds up the melting process of the metals and improves the efficiency.

Less consumption, less pollution

Graphite electrodes are critical in steel making using recycled steel scrap. It helps in the progress of decarbonization.

Excellent sustainability

As the graphite electrode has good oxidation resistance, it will not melt or degrade. The continuity and stability of the steel-making process is guaranteed.

Safe to use

The graphite electrode is changed less, which reduces the amount of labor and the risk factor of the operator.

Graphite Electrode Uses

graphite electrode used for EAF

EAF

As more and more steel plants choose to melt the steel by electric arc furnaces, the demand for eaf electrodes takes up 70-80% of graphite electrode consumption. The EAF electrodes can serve as the induction part that generates an arc carrying high heat to melt the steel scrap in the EAF.

graphite electrode for submerged arc furnace

Submerged arc furnace

Submerged arc furnace is mainly used for the production of ferroalloy, pure silicon, calcium carbide, and matte. Graphite electrodes are buried in the charge material in a submerged arc furnace. In addition to the heat generated by the arc between the plate and the charge, the resistance of the charge also generates heat when the current passes through the charge.

graphite electrode for ladle furnace

Ladle Furnace

Graphite electrodes are often utilized in three-phase AC ladle furnaces. Ladle furnaces are also a piece of important equipment in steel plants. An LF is mainly used to finish the process of further reduction and refining once the slag has been mixed out.

EAF electrode Manufacturing process

Graphite electrode is mainly made of petroleum coke and needle coke as raw materials, and coal pitch as a bonding agent. The production process includes raw material calcination, crushing and grinding, batching, mixing, molding, roasting, impregnation, graphitization, and machining.

EAF graphite electrode production process

Raw Material Preparation: This involves calcination of the raw materials, followed by crushing and grinding to achieve the desired particle size.

Batching and Mixing: The prepared raw materials are accurately weighed and mixed together to ensure a homogenous composition.

Molding:The mixed materials are then molded into the desired shape using specialized molds or presses.

Roasting: The molded shapes undergo a roasting process in a controlled environment to remove any remaining volatile components and strengthen the structure.

Impregnation: Some processes may involve impregnating the roasted materials with specific substances to enhance their properties.

Graphitization: The roasted and impregnated materials are subjected to high temperatures in a graphitization furnace to transform them into graphite structures.

Machining: The graphite products are then machined to achieve precise dimensions and surface finishes according to the required specifications.

Quality Control: Throughout the production process, rigorous quality control measures are implemented to ensure the final products meet the required standards.

Packaging and Shipping: The finished graphite products are carefully packaged and prepared for shipping to customers or distribution centers.
