Knife Gate Key Specifications

Actuation

Pneumatic cylinder for automated process control in DRI and flux handling; hydraulic for high-force applications; manual hand wheel for maintenance isolation points.

Sealing Type

Standard sealing for coarse materials like pellets and coke; low-leakage seals for fine DRI fines and flux powder to prevent material loss and dust emissions.

Seating Configuration

Hard seated (metal-to-metal) for hot DRI at temperatures up to 400°C; soft seated with high-temperature silicone or Viton seals for ambient iron ore and flux service.

Port Shape

Circular ports for pipeline connections in DRI transfer systems; square and rectangular ports for hopper and chute installations in flux and coke handling.

Body Material

Mild steel body with Hardox 500 blade and wear liners for maximum abrasion resistance; stainless steel option for corrosive pickling line applications.

Size Range

Available from 150 mm to 1200 mm to accommodate various material flow rates in DRI kilns, blast furnace feed systems, and steel plant material handling.

Industrial Applications

DRI Kiln Discharge
Installed at rotary kiln discharge ends to control hot DRI flow to cooling systems, with hard-seated metal construction rated for temperatures up to 400°C.
Blast Furnace Flux Feeding
Positioned at flux (limestone, dolomite) storage bin outlets to regulate feed rate to blast furnace skip hoists or belt charging systems.
Coke Oven Feed Hopper
Mounted at coke breeze and coke hopper discharge points to control material feed to sinter plant or blast furnace burden preparation systems.
