AI for Slag Detection
What is Slag?
Slag is a non-metallic byproduct generated during various stages of steelmaking, such as in the Blast Furnace (BF), Basic Oxygen Furnace (BOF), Electric Arc Furnace (EAF), converter, ladle, and many more. It forms when impurities from raw materials — including silica, alumina, phosphorus, sulfur, and ash — combine with fluxes like lime. This mixture floats on top of the molten steel because of its lower density, creating a separation layer between pure hot metal and impurities.
Why Is a Slag level Detection is Important in Steel Plants?
Slag level detection is critical in steel plants because it ensures cleaner steel, safer operations, and more efficient tapping. Accurate monitoring of the transition between slag and steel is essential for process control.
When slag levels are not monitored accurately, slag carryover can contaminate molten steel, increase defect rates, and raise refining costs. It also accelerates refractory wear, reducing equipment life and causing more frequent shutdowns. Additionally, inaccurate molten metal level readings increase the risk of overflows, bursts, and splashes—leading to safety hazards, equipment damage, and unplanned production stoppages. Reducing operator intervention through automated monitoring improves safety and efficiency.
Accurate slag level detection helps maintain process stability, reduce losses, and improve overall operational reliability. The advantages and benefits of slag level detection for the steel industry include supporting the ongoing process, meeting the increasing demand for high-quality steel, and ensuring safer, more efficient, and reliable operations.
Key Reasons:
Ensures cleaner steel and better product quality by preventing slag carryover and reducing defects.
Reduces operational costs by lowering refining needs, alloy corrections, minimizing hot metal losses, and reducing maintenance requirements.
Protects equipment and refractories, reducing corrosion, extending furnace life, and preventing damage from overflows or splashes.
Improves operational stability by avoiding unplanned stoppages and ensuring safer, more consistent tapping operations.
Customers benefit from improved reliability and reduced maintenance needs, ensuring efficient and dependable slag detection solutions.
