From the electric arc furnace to the ladle — full-range magnesia-carbon and dolomite refractory linings for the entire steelmaking route.
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.
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.
Magnesia-carbon linings for the barrel, trunnion, cone and tap-hole zone — pitch-bonded and resin-bonded grades available.
Magnesia-carbon bricks and castable linings for ladle sidewalls, bottoms and slag lines. Extended campaign life under secondary metallurgy conditions.
Dolomite and magnesia-chrome linings for hot metal transport vessels, resistant to iron and slag erosion at transport temperatures.
Magnesia-carbon and magnesia-chrome bricks for RH degassers, VOD vessels, LF furnaces and tundishes.
Castables, ramming mixes and gunning mixes for repairs, permanent linings and working-face applications throughout the route.
