Carbon Plant and Rodding Room Practices




Some of the difficulties and problems that are felt in the potroom are stem from anodes quality;

poor practices in the rodding room or of carbon anodes production can lead to increased air burn, carbon dust formation, spikes, and reduced current efficiency.

LMRC can help using their extensive experience in anode production process from raw material to finished anodes, both to fix problems within the anode formation process and design a system to maintain anode quality




Carbon Plant Expertise




In the anode carbon plant LMRC can help with:

  • Carrying out a pitch cost/anode property trade-off assessment.
  • Setup/improve data management for pitch viscosity, temperatures and fractions
  • Setup/improve data management for green anode properties
  • Optimizing baked anode properties (such as CO2 reactivity, air permeability, flexural strength, baked density)
  • Reducing anode cracking.
  • Reducing packing coke sticking.



Rodding Room Support




In the rodding room LMRC can:

  • Provide technical support for correct cast Iron recipe, improving thimble stripping and reduce contamination.
  • Improve rodding practices to reduce reactive anode problem.
  • Improve anode’s poor current distribution by improving casting.
