Quality Control

For controlling the quality of the Carbon Paste/Tamping Paste, well experienced personnel having long experience in the field of Carbon Products is in charge. For controlling the Carbon fines quality the operating parameters will be fixed and maintained. The quality of Carbon fines will depend mainly on screen analysis and raw material quality. However the laboratory results will ensure the final product quality.

Research / Testing Facilities

Maruti Research and Development Centre has sophisticated equipment and extensive testing facilities to ensure world – class products. The Centre carries out the following activities:

  • Analysis of various raw materials for manufacture of Carbon Electrode Paste and Blocks.
  • Simulation analysis of electrode under industrial baking condition.
  • Determination of physical and chemical properties of the Electrode Paste test samples.
  • Analytical work on Carbon Block test samples to determine their physical and chemical properties.
