Steel & Sponge Iron Plants

Steel plants rarely get a long clean shutdown. Most of this work happens in a four-hour window against a plant that is otherwise running — which is why a method needing no confined-space permit, no gas testing and no rescue standby team is worth more here than anywhere else.

Where we work in your plant

• Sinter hoppers and bunkers — hot, abrasive material bridged across the outlet
• DRI and sponge iron hoppers — hot discharge and packed fines
• Slag hoppers and pits — set and fused material no vibrator will move
• Flux and additive bunkers — lime, dolomite and limestone caked with moisture
• Iron ore fines bins — wet fines that bridge, particularly through the monsoon
• Uptake pipes and furnace build-up — cleared from outside the shell
• Blast furnace applications, including hearth work

Why the method suits steel

Hoppers here are smaller than cement silos and blockages sit at the cone and outlet. That suits the Cardox CO₂ System — a tube through a wall socket breaks the blockage in milliseconds — better than a boom lowered from above. Larger bunkers still get the whipping system for wall build-up.

Everything works at temperature. Nothing cools down first, which is the difference between a job that fits your window and one that does not.
