Austria produces some petroleum and natural gas to meet its own needs, and it also mines coal, iron ore, copper, lead, zinc, antimony, and graphite, used in industry. A high graphitization potential will result in irons with graphite as the rich carbon phase, while a low graphitization potential will result in irons with iron carbide.

Aluminium smelting - Wikipedia
Aluminium smelting is the process of extracting aluminium from its oxide, alumina, generally by the Hall-Héroult process.Alumina is extracted from the ore bauxite by means of the Bayer process at an alumina refinery.This is an electrolytic process, so an aluminium smelter uses huge amounts of electricity; smelters tend to be loed close to large power stations, often hydro-electric ones, in

We are the only graphite electrode producer that is substantially vertically integrated into petroleum needle coke, the key raw material for graphite electrodes. Vertical integration has allowed us to adopt a commercial strategy with long-term, fixed price, fixed volume, take-or-pay contracts providing earnings stability and visibility.

Optimizing Thermal Processes in Carbon Manufacturing …
5/7/2018· In our graphitization model, we use Joule heating physics together with the thermal stress calculation. Besides the anisotropic and temperature-dependent material properties like thermal conductivity, electrical resistivity, and coefficients of the thermal expansion, we can also measure high-temperature stress-strain behavior in our lab, and we implement all of these properties in our model.

Coke Calcination Levels and Aluminum Anode Quality
The calcination temperature of petroleum coke for aluminum anode appliions has been generally increased during the past 10 years. This change by coke suppliers has often been done at the request of anode manufacturers (smelters) who seek special quality requirements for the calcined coke.
