Steel Industry
High-Temperature Flow Control for Integrated Steel Plants
Steel manufacturing is defined by thermal intensity, material abrasion, and continuous operation. From raw material preparation to direct reduction and dust recovery systems, steel plants operate under extreme temperature gradients, heavy particulate load, and high-volume material movement. Rotary Air Locks are critical components in maintaining pressure isolation, controlled discharge, and dust containment across steel production systems.
What This Industry Demands
High-temperature process zones with abrasive lime and iron ore fines
Dense particulate dust from blast furnaces, BOF, and EAF processes
Continuous-duty bulk handling under fluctuating pressure environments
Standard rotary valves fail prematurely, high-temperature resilience is essential
Where We Apply in Steel
Lime Handling Systems
Abrasive and Heavy Duty Series for lime used in blast furnace fluxing, desulfurization, and slag conditioning, providing reinforced SLV liners, hardened rotor tips, and long operational life.
Sinter & Pellet Plants
Stable discharge under high dust load with effective pressure isolation, protecting baghouse efficiency and supporting consistent sinter quality and plant efficiency.
DRI (Direct Reduced Iron) Systems
RALX High-Temperature Series with thermal expansion management, outboard bearing protection, and heat-resistant sealing systems for iron ore feeding and char discharge in high-temperature reduction circuits.
Dust Extraction Systems
Controlled dust discharge from blast furnace, BOF, and EAF dust extraction systems with stable pressure isolation, minimal air infiltration, and continuous discharge reliability.
In steel production, process stability and thermal control are fundamental. Air leakage or unstable discharge can result in reduced furnace efficiency, higher fuel consumption, dust emission violations, increased equipment wear, and operational downtime. High-temperature resilience and mechanical strength are non-negotiable.
How We Engineer for This Duty
High-temperature-resistant housings with reinforced heavy-duty construction
Tungsten carbide rotor tips and replaceable wear liners for abrasive duty
Optimized rotor clearance with high-load bearing assemblies
Continuous-duty drive compatibility for integrated steel plant operation
Temperature-capable sealing systems protecting against thermal distortion
