Products & ServicesManufacturing Process

Old refrigerators, used dishwashers, leftover vehicle parts. All the usable metal from manufacturing and consumption – where does it go? With the help of graphite electrodes, which conduct enough electricity to melt scrap steel, most of it gets turned into new steel.

At GrafTech, we help customers find ways to make a time-tested process as advanced and efficient as possible.

What is a Graphite Electrode

An essential component for the world's largest recycling industry.

1

Mill mix and
forming

We crush, screen and hot-blend premium quality calcined petroleum coke with pitch in controlled proportions. We extrude the resulting plastic mass through a forming press and cut it into specified lengths – so-called green electrodes – before cooling them in a controlled water bath.

2

Baking

We place green electrodes into large cans called saggers (pronounced say-gers) and bake them in computer-controlled furnaces at 800°C (1400°F) for up to two weeks. We then cool, clean, inspect and sample-test the baked electrodes made of amorphous carbon.

3

Pitch Impregnation

We impregnate the baked electrodes with a special pitch to give them the higher density, mechanical strength and electrical conductivity they will need to withstand severe EAF operating conditions.

4

Rebaking

A second baking cycle, or “rebake,” carbonizes the pitch from impregnation and drives off remaining volatiles. Rebake temperatures reach almost 750°C (1300°F).

5

Graphitizing

We lay the electrodes end-to-end and heat them to over 3000°C (5000°F). This restructures the carbon to its crystalline form: graphite. Then we cool, clean, inspect and sample-test the electrodes again.

6

Machining

Next, we turn an electrode’s outer diameter to its finished dimension and add threaded sockets to its ends. Along with threaded graphite connecting pins, these sockets allow our customers to join electrodes together into columns.

Shipping

Finally, we inspect, cap and palletize finished electrodes for our global customers. A prominent UCAR® Graphite Electrode logo speaks to the shipped product’s pedigree and quality.

Products & ServicesUCAR® Graphite Electrodes

Electric arc furnaces demand graphite electrodes – the only product that can conduct the power and withstand the heat necessary to make steel. Because one size does not fit all, we offer multiple grades and sizes of graphite electrodes to meet the needs of our global customers.

Our Plant

Seadrift’s facility was designed specifically for the production of petroleum needle coke. The plant is nearly self-sufficient, requiring only feedstock supplies and fresh water to run continuously. Inside, our advanced equipment and process technologies can adapt to a wide variety of raw materials and process variables – while consistently delivering a high-quality product for customers.

Strategically located on the mid-Texas coast, we enjoy ready access to efficient shipping routes, a well-educated workforce and other Gulf refineries for feedstock supply.

Our Process

In our advanced facility, we produce petroleum needle coke through a multi-step process, which we continuously monitor, sample and test.

Coking

Decant oil feed is preheated, separated by fractionation and reheated to temperatures hot enough to induce an endothermic reaction and form green coke.

Drying

Superheated gases pass through the green coke in a drying drum. This reduces volatile matter and hardens the coke.

Removal and Calcining

High-pressure water removes or “cuts” the coke from the drum. The green coke then undergoes a calcining process: it is fed through a rotary kiln at temperatures in excess of 1100°C (2000°F), which controls coke density and burns off any remaining volatiles in the coke.

Cooling, Storage and Shipping

The newly formed needle coke is cooled and conveyed to a storage silo. The final product can then be shipped by rail, truck or barge.
