As steel producers manage headwinds associated with increased electrode pricing for electric arc furnace (EAF) and ladle metallurgy facility (LMF) operations, they are tasked with reducing their carbon footprint while increasing plant throughput capacity. ChemTreat’s Primary Metals team and dedicated R&D scientists have developed an exciting solution to help our clients address these challenges.
Our innovative and patented Electrode Consumption Reduction (ECR®) technology uses the novel process of applying an antioxidant barrier to the electrode surface while the furnace is in operation.
ECR is an automated way to extend electrode life while simultaneously improving production throughput and reducing greenhouse gas emissions.
ChemTreat’s ECR process is continuously applied to the spray water system and distributed on the electrode surface via the spray ring. As the water evaporates, a visible protective barrier is formed on the electrode surface.
This patented process not only provides a protective barrier above the furnace delta, but also delivers further oxidation protection as the electrode penetrates the furnace. Once inside the furnace, the oxidation barrier becomes molten, extending protection down the electrode, and ultimately reducing the associated red length.

The program is controlled with automation engineered to provide the following benefits:
Your experienced ChemTreat Primary Metals team will customize the program for each furnace at your facility. The program design will be based on the furnace operation, specific spray water chemistry, related equipment, and the associated heat flux.
