Iron & Steel Industry equipment scope

Filter, fan, filter bag, filter cage and auxiliary equipment selection by process

In iron and steel plants, melting fumes, hot metal oxide, slag, and mill scale cannot be handled with the same system approach. Extraction hoods, ductwork, baghouse filters, process air equipment, compensators, and discharge equipment are evaluated together based on process temperature and fume load.

Process filtration, fan, and equipment scope for Iron & Steel Industry

Process-based system approach

The filter housing, fan, ductwork, filter element, pulse-jet system and discharge/conveying equipment are not independent of one another; they are evaluated as components of the same operating point.

Information clarified before quoting

Flow rate and fume peaks: Furnace cycle, lid/charging events and simultaneous extraction points
Gas temperature: Continuous/peak temperature and spark behavior
Dust composition: Metal oxide, carbon, slag and oily fume
System pressure: Hood, ductwork, damper and filter ΔP
Discharge: Hopper, rotary valve, screw conveyor and container layout

Equipment scope by process point

Process Dew Point	Filter / dust-fume solution	Fan, ductwork and conveying equipment	Critical selection grade
Electric arc / induction furnace	Primary-secondary fume extraction, baghouse filter, or suitable pre-separation	High-pressure ID fan, water-cooled ductwork/suitable expansion joint	Sudden fume peaks, sparks, high temperature and carbon loading
Ladle, casting and transfer	Hood-based local fume collection, baghouse connection	Booster fan, damper and high-temperature ductwork	Moving source, lid opening and false-air control
Slag crushing and screening	Cyclone pre-separator + abrasion-resistant baghouse filter	Dust collection fan, rotary valve and screw conveyor discharge	Abrasive coarse particles, sparks and hopper wear
Rolling mill and scale points	Local extraction, cartridge/bag filter, or a suitable separator	Exhaust fan, ductwork, damper and transfer equipment	Oily fume, metal oxide and maintenance access
Shot blasting, grinding and surface cleaning	Cartridge or bag-type dry dust collection	Local extraction fan, cyclone separator and rotary/drum discharge	Fine metal dust, wear and combustible dust review

Equipment groups used in this industry

Expansion joint, rotary valve and screw conveyor

Combined solution for hot-duct expansion and filter hopper discharge.

How do we determine capacity and technical specifications?

Exact capacity is not set by a catalog name; it is determined by process flow rate, system pressure, temperature, material/dust behavior and discharge continuity.

technical data	Required site / process information	Impact on selection
Flow rate and fume peaks	Furnace cycle, lid/charging events and simultaneous extraction points	Determines the fan and filter area.
Gas temperature	Continuous/peak temperature and spark behavior	Changes the media, ductwork and pre-separation decision.
Dust composition	Metal oxide, carbon, slag and oily fume	Determines bag surface and abrasion protection.
System pressure	Hood, ductwork, damper and filter ΔP	Determines the fan motor and operating point.
Discharge	Hopper, rotary valve, screw conveyor and container layout	Affects continuous operation and fire risk.
