Graphite products possess high thermal resistance and excellent strength characteristics, thanks to unique physical and chemical properties. These parameters, in combination with small porosity of graphite, allow to make high-quality metallurgical graphitized electrodes and to exclude emergency processes.
Qualitative graphite products are an irreplaceable element of difficult and power-intensive technological processes.
The graphitized electrodes are made on the basis of oil and needle coke and coal-tar pitches. Such graphite products the rudotermicheskikh and other electrotechnical installations is used in arc steel-smelting furnaces, refining, ferroalloy furnaces.
The production range where graphite products and carbon-containing materials are applied, is extremely wide. It and the graphite blades used in grooves of rotors of electric motors it and technological processes of smelting became, resistance furnaces working in vacuum or the protective environment, graphite products are also used in production of semiconductor materials and in many other difficult, responsible and hi-tech productions.
The AvtokomTehnolodgy group of companies is the official representative of producer the graphite products Kroma Ltd (Serbia)
We deliver graphite sliding bearings, blades of vacuum pumps and compressors, segment mating rings, mating rings of steam heads and a saddle of the spherical valve, graphite components the used in production of glass products, processes of continuous molding, graphitized electrodes and components for the overworking and chemical industry.
The continuous casting process is used increasingly more often to replace the conventional rod and tube manufacturing process. It is particularly advatageous for some metals such as cast iron, copper, aluminium, and precious metals (gold, silver, etc.). Depending on application, we supply flat and cylindrical dies of required shapes and dimensions.

Electroerosion machining (EEM) is based on the material surface layer destruction principle under external electrical discharge impacts.
The materials used for the manufacture of electrodes shall have a high level of erosion resitance and ensure stable operation within the entire EEM operating range and maximum prooductivity with little wear and tear. Graphite is one of the materials having the best characteristics in respect of electrode erosion resistance and EEM process stability.
The advantages of graphite as a material for electrode production: heat resistance, electrical conductivity, resistance to different mechanical deformation conditions and temperature deformations.
- Graphite electrodes in the chemical industry
- Graphite electrodes in the electric arc furnace
Graphite electrodes of erosimates
- Graphite electrodes in the process and chemical industries
Advantages of graphite as a component production material in the chemical and process industries:
- good corrosion resistance
- good heat conductivity (up to 140W/(mВ·K)) and resistance to sharp temperature fluctuations
- heat stability in non-oxidizing atmosphere up to 3000ВєC
- heat stability in oxidizing atmosphere up to 500ВєC
- easily machinable using standard methods
Having the above advantages, the material is used for component production in the petrochemical industry (hydrochloric acid synthesizing plants, sewage and exhaust gas treatment plants, heat exchangers).
