Red Lead Furnaces
Eagle’s Red Lead Furnace was developed in cooperation with a leading independent U.S. lead oxide producer and is engineered to deliver consistent, high-quality red lead for batteries, leaded glass, ceramics, and specialty chemical applications.
Three furnace models (RLF 1000, RLF 2000, and RLF 3000) are available to support varying production capacities and target red lead percentages. Using leady oxide feed material, the system produces a wide range of red lead concentrations — from approximately 20% to 98% Pb₃O₄ — based on customer requirements. Production rates depend on feed material and operating conditions, allowing manufacturers to tailor output for specific products and performance goals.
Why Use Red Lead in Batteries?
- Faster Formation Time
- Improved Deep Cycle Performance
- Improved Reserve Capacity

Rates are dependent on materials used and manufacturing conditions. Rates noted are from using leady oxide feed material with 15% free lead.
Eagle's Advanced PLC Systems Put Operators in Control of Each Batch
Red lead is formed by heating PbO to a temperature of 450 to 500 C, then holding within this range until the desired percentage of the material is achieved. The conversion is a controlled reaction of “time-and-temperature”.
With Eagle’s unique temperature monitoring and PLC control algorithms, our systems easily allow operators to monitor all aspects of furnace operations along with feed and discharge systems throughout the entire batch process.
Our Red Lead Furnaces are refractory-lined batch ovens. Using four large rotating agitator arms, the feed material is continuously mixed to ensure a consistent percentage of Red Lead throughout the batch. Batch temperature is controlled by electric heating elements isolated below the reaction chamber. The oxygen content of the air inside the furnace is monitored with oxygen automatically added to maintain the desired level for a proper reaction.
