Development of equipment for high-temperature measurements of thermal conductivity and electrical conductivity

Keywords
Energy and Energy Efficiency

Description
Measurement of thermal conductivity and electrical conductivity of monolithic materials and bulk material with the material particle size distribution between 0 and 15 mm in the temperature range 400–1500 K under overpressure up to 50 kPa.

Innovative aspect and main advantages:
Determination of thermal conductivity is based on the principle of superposition of temperature fields in the study of materials that ensure improved accuracy measurements over a wide temperature range. High temperature electrical conductivity measurements in bulk materials are carried out by measuring cell with diameter of 100 mm and height 250 mm and with a uniform temperature field in the test material, which ensures increasing the accuracy of measurement.

Problem solved:
For units and electro-metallurgical industries, which are characterized by high energy intensity, widely used bulk carbon materials as insulation and active electrical resistance. Right-size carbon blend permits to increase energy efficiency of high-temperature units. The use of measuring equipment for developing thermal insulation for the construction industry.

Potential customers, markets:
Enterprises electrode industry, ferrous and non-ferrous metallurgy, construction industry, resource and energy saving, etc.. Enterprises users: PJSC "Ukrahrafit", research institutions.
