Steel Plants & Metal Foundries
Metal refining, cupola furnace melting, and mini-steel mills require continuous forced combustion air to maintain melt temperatures above 1,500°C. SAE heavy-duty Roots blowers supply stable, high-pressure blast air that overcomes deep coke and scrap metal beds.
Critical Engineering & Design Requirements
- High Static Pressure Capability: Delivers up to 1.0 kg/cm² pressure to push combustion air through deep furnace burden.
- Rugged Foundry-Grade Construction: Heavy-duty grey iron FG 260 casings withstand ambient foundry heat, vibration, and dust.
- Direct-Coupled or Heavy V-Belt Drives: Heavy-duty taper-lock pulleys and industrial bearings designed for continuous metal melting shifts.
Engineering Selection Advice
Water-cooled blower models are strongly recommended in foundry environments where ambient temperatures near cupolas exceed 50°C.

Frequently Asked Questions – Steel Plants & Metal Foundries
Q:Why choose Roots blowers over centrifugal fans for cupola furnaces?
Roots blowers maintain constant air volume even when scrap metal settles and resistance increases, preventing combustion drops and cold heats.
Q:Can SAE blowers handle carbon injection in electric arc furnaces?
Yes, SAE positive pressure blowers are widely used to inject pulverized carbon and lime directly into molten steel baths.
