Iron and Steel Industry

Iron and steel production is a demanding industry characterized by high temperatures, abrasive dust, and constantly changing process conditions. In such an environment, the effectiveness of filtration systems is critical for both production efficiency and environmental compliance.

At Luft Filter, we analyze the specific needs of iron and steel plants and provide the most suitable filtration solutions for their processes. In applications such as electric arc furnaces (EAF), ladle metallurgy furnaces (LMF), blast furnaces, and sintering plants, we recommend filter bags and systems that are resistant to high temperatures and abrasive dust.

Filtration Applications in Iron and Steel Production

Electric Arc Furnaces (EAF) & Ladle Metallurgy Furnaces (LMF):

During melting operations, fine dust and gases are generated at temperatures below 160°C and are typically captured via canopy systems. In this environment, the filtration system may also be exposed to oil vapors from scrap, acidic gases, and occasionally moisture/steam due to pipe damage in cooling towers. For such complex process conditions, filter bags made of polyester, acrylic, or aramid are recommended. In areas where there is a risk of sparks, flame-retardant coated filter media should be used for enhanced safety.

Blast Furnaces:

Due to the continuous high temperatures (>200°C) and highly abrasive dust (oxide, silica, and carbon-based particles), durable filter media combinations with high thermal resistance—such as fiberglass, P84, or aramid—are required for long service life.

Sintering Plants:

Sintering generates high temperatures, rapid thermal fluctuations (thermal shock), and chemically aggressive gases. Filter bags made of aramid, fiberglass, P84, or PTFE are preferred. Flexible filter media structures are recommended for better resistance to thermal shock.

General Dedusting Systems:

In medium- to low-temperature processes with lower abrasive impact, surface-treated polyester bags or acrylic-based solutions are used to create energy-efficient systems with minimal maintenance requirements.

Our Filtration Expertise in the Iron and Steel Industry

Luft Filter supports the safe and efficient operation of iron and steel plants with filter bags and engineering-driven solutions specifically developed for extreme conditions such as high temperatures, heavy metal dust, thermal shock, and corrosive gases.

In our production processes, we focus on key performance criteria such as resistance to continuous high temperatures, acid and alkali durability, flame-retardant properties, and low differential pressure loss.

Starting from process analysis of dust collection systems, we provide end-to-end services including proper fabric and membrane selection, metallurgically compatible bag design, on-site supervision, and periodic maintenance consultancy.

We develop customized solutions based on the unique gas composition and dust load profile of each line—reducing unplanned shutdowns, extending filter bag life, and minimizing energy consumption.

Even in the most demanding processes, Luft Filter solutions deliver maximum filtration performance and operational sustainability. With our engineering expertise in the industry, we are a trusted solution partner for iron and steel plants.
