Steel Industry

We may be tough with fire, but we are gentle with steel.

With a history of more than 50 years in the steel industry, Mathios Refractories stands in the position to effectively meet the needs of its refractory partners. We offer concepts and solutions that always fit precisely individual customer cases and projects. Hereby, we are backed by our comprehensive range of refractory products. We are able to provide bricks, monolithic, precast sections as well as special parts, specifically designed for the refractory lining of plants like those listed below:

  • Tundish
  • Ladle for Secondary Metallurgy
  • E.A.F (Electric Arc Furnace)
  • Pusher Type Reheating Furnace

Having a sound knowledge of the production process behind the steel industry, we, at Mathios Refractories, focus on improving energy efficiency, reduced downtime and shorter repair cycles of steel plants.

Tundish

Working Lining Permanent Lining Impact Pads
Slag Wares Insulating Lining Well Blocks

Tundishes are containers which are used to feed molten metal into caster moulds. They act as reservoirs of molten metal that feed continuously the casting process, while ladles are being swapped. Extremely high temperatures, thermal shock and infiltration of liquid steel and its slags, are the main challenges imposed on their refractories. Through thorough R&D and application experience we have developed, and continuously keep developing, materials suited specifically for the steel making industry.

The refractory materials offered by MATHIOS REFRACTORIES are vastly tested and proven by the industry.
Products from the following lines are recommended by our experts:

  • MAT PLUS: Alumina (Al2O3) low cement castables (LCC), with formulations based on mullite, andalusite, bauxite, sintered alumina and corundum for use as permanent linings, impact pads, slag wares and well blocks
  • MAT MICRON: Alumina (Al2O3) ultra-low cement castables (ULCC), with formulations based on bauxite for use as permanent linings, impact pads and slag wares
  • MAT TUN : Magnesite (MgO) mixes, with formulations based on magnesia for use as working linings

Ladle for Secondary Metallurgy

Filling Materials Well Blocks Metal Zone Slag Zone
Safety Lining Cover Emergency Lance Safety Lining of Slag Zone
Insulation of Cover Impact Zone

Α ladle for secondary metallurgy is a vessel used to transport and pour molten metals. They are used in foundries (small units) and in secondary steelmaking (large units). Extremely high temperatures, thermal shock and infiltration of liquid steel and its slags, are the main challenges imposed on their refractories. Through thorough R&D and application experience we have developed, and continuously keep developing, materials suited specifically for the steel making industry.

The refractory materials offered by MATHIOS REFRACTORIES are vastly tested and proven by the industry.
Products from the following lines are recommended by our experts:

  • IDEAL: Alumina (Al2O3) bricks, with formulations based on clacined fireclay, chamotte, mullite and bauxite are used as safety linings
  • MAT PLUS: Alumina (Al2O3) low cement castables (LCC), with formulations based on andalusite, bauxite, sintered alumina – spinel, for use as well blocks, cover, emergency lance and impact zones
  • MAT MICRON: Alumina (Al2O3) ultra-low cement castables (ULCC), with formulations based on andalusite and bauxite for use as cover, emergency lance and impact zones
  • MAT: Alumina (Al2O3) regular castables (dense), with formulations based on bauxite for use as filling materials
  • MAT (G): Alumina ((Al2O3) insulating castables & gunning materials, with formulations based on vermiculite for use as cover insulation
  • MAT SF: Alumina (Al2O3) self-flowing ultra-low cement castables (SF ULCC), with formulations based on sintered alumina for use as well blocks

IDEAL: Magnesite (MgO) bricks, with formulations based on magnesia and carbon for use as slag zone linings

E.A.F (Electric Arc Furnace)

Roof – Delta Section Electrode Rings Bottom Lining Side Walls
E.B.T Lining Safety Lining Tap Hole / Runner

Electric arc furnaces (EAF) heat and melt metals using alternating or direct current They are used both in foundries (small units) and in secondary steelmaking (large units). Extremely high temperatures, thermal shock and infiltration of liquid steel and its slags, are the main challenges imposed on their refractories. Through thorough R&D and application experience we have developed, and continuously keep developing, materials suited specifically for the steel making industry.
