Top Considerations for Implementing & Maintaining Lime Injection Systems

Efficiency is important for maintaining a competitive edge in electric arc furnace (EAF) steel production. Traditional methods of adding lime to the furnace, such as via super sacks, conveyors, or bucket cranes, are difficult to control and result in product waste and dust. Lime injection systems can play a vital role in improving operations in steel plants, but proper system design and maintenance are essential.

Steel Plant Shop Safety and Lime Injection System Design:

To reduce lime waste, minimize dust emissions, and improve overall worker safety, your lime injection systems should establish a closed-loop environment from offload to injection.

How we can help:

In partnership with Coperion and Tallman Technologies, our experienced Carmeuse Systems engineering teams collaborate with you to understand your site needs and design the right lime injection solution for your operation.

Accounting for Material Size:

Starting with the right size material and addressing material degradation helps maintain uniform lime injection and improve system effectiveness. To enhance performance, opt for a system design with injection technologies that are able to convey a wider range of particle sizes.

How we can help:

Our solution’s lime injector ensures accurate, reliable, and uninterrupted lime supply, even with raw material size variations. Uniform injection comes from the way we feed the lime into the convey line, using a rotary valve metering device to ensure a uniform feed. Carmeuse, our parent company, is also a global leader in lime manufacturing, which enables our team to provide advanced expertise in all things lime, including its chemical and physical properties, raw material testing, and application.

Equipment Configuration and Start-Up:

Factors like injector placement, pressure, and flow rates impact lime dispersion and dissolution. The proper equipment configuration is key for optimizing performance and forming an effective foamy slag. Additionally, lime injection systems require fine-tuning during start-up to ensure efficient and consistent lime delivery.

How we can help:

Our experienced technicians can assist with optimizing settings to achieve smooth startup, based on the characteristics of your lime supply and system configuration.

Ongoing Maintenance and Support

Routine maintenance is essential to keep your systems running smoothly and safely. Regular inspections, seal checks, pressure monitoring, and calibration ensures consistent lime delivery and can extend the lifespan of your equipment.

How we can help:

Our experienced technicians are available for onsite diagnosis of current problem areas and can provide recommendations for system enhancements and maintenance. This trained team can assist in examining and refurbishing installed lime injection equipment, retrofitting an existing furnace or supporting a new furnace installation.
