Iron & Steel Refractories

From the electric arc furnace to the ladle — full-range magnesia-carbon and dolomite refractory linings for the entire steelmaking route.

The largest share of our business — and where our depth shows.

Steel is the most demanding segment in refractories. Rapid temperature cycling, aggressive slag attack, mechanical stress from charging and tapping — the lining has to perform under conditions that would destroy a lesser product. KONREF has supplied the iron and steel industry since 1966, and it remains the segment where our vertical integration delivers the most value.

Because we produce our own Dead Burned Magnesia, we control purity and grain size from the mine outward. That means consistent MgO content from batch to batch — critical for predictable lining life in high-throughput steel plants.

Every stage of the route.

Electric Arc Furnace

Magnesia-carbon bricks for sidewalls, hot-spot zones and delta zones. High-carbon and low-carbon grades matched to your power input and scrap mix.

Basic Oxygen Furnace

Magnesia-carbon linings for the barrel, trunnion, cone and tap-hole zone — pitch-bonded and resin-bonded grades available.

Steel Ladle

Magnesia-carbon bricks and castable linings for ladle sidewalls, bottoms and slag lines. Extended campaign life under secondary metallurgy conditions.

Torpedo Car / Mixer

Dolomite and magnesia-chrome linings for hot metal transport vessels, resistant to iron and slag erosion at transport temperatures.

Secondary Metallurgy

Magnesia-carbon and magnesia-chrome bricks for RH degassers, VOD vessels, LF furnaces and tundishes.

Monolithic Solutions

Castables, ramming mixes and gunning mixes for repairs, permanent linings and working-face applications throughout the route.

Supply security and consistent quality — not commodity trading.

  • Own DBM — consistent raw material purity from our own mine and rotary kiln, not sourced from volatile spot markets.
  • Non-China source — increasingly important for EU and US steel mills de-risking their refractory supply chain.
  • Technical support — our engineers visit customer plants to assess wear patterns and recommend lining adjustments.
  • Custom grades — composition and carbon content tuned to your specific furnace, power input and slag chemistry.
  • ISO 9001 since 1996 — traceable quality records for every shipment.
