Refractory bricks, built from the raw material up
MgO-C, AMC, flow-control and fired basic bricks for steel plants and kilns. We source the raw materials through the network we have built since 1990, produce at partner plants in China, India and Europe under our own control, and deliver from stock.
From our mineral network to your lining
A brick is only as good as its aggregate. We have traded refractory raw materials for more than thirty years, so we know which kiln a magnesia or bauxite came from before it ever goes into a press.
Raw materials
Fused and large-crystal magnesia, sintered magnesia, bauxite, corundum and graphite from producers we have worked with for decades.
- Fixed offtakes
- Lot traceability
Production
Bricks are pressed at partner plants chosen for each product line and market.
Our control
We set the recipe and grain sizing, approve pressing and curing or firing, and our own quality staff test every lot before it is released.
- Recipe
- Pressing
- Testing
Delivery
Shipped to your plant or held in our warehouses in Turkey and Europe, so linings can be called off when a campaign needs them.
- Gebze stock

Bricks for every zone of the melt shop

MgO-C bricks
EAF walls, hot spots and slag line; ladle slag line, wall and bottom. Three series, grades A to D plus AOX.
AMC bricks
Alumina-magnesia-carbon for ladle bottoms and impact pads, with in-situ spinel for tight joints.
Flow control
Slide gate plates, ladle nozzles and purging plugs, tundish nozzles and EBT tap-hole sets.

Fired basic bricks
Magnesia for safety linings, magnesia-chrome for refining and non-ferrous, magnesia-spinel for kilns.

Monolithics
EAF ramming mix, gunning mixes for hot repair, tundish coating and dry vibratable mixes.

Raw materials
The same network supplies brick and castable makers with bauxite, aluminas, mullite, magnesia and more.
Where our bricks go
Each zone of a furnace or ladle wears differently, so each gets its own grade. These are the typical placements; we size the lining to your practice and campaign targets.
Electric arc furnace
Steel ladle
MgO-C bricks
Resin-bonded bricks of high-purity magnesia and flake graphite, for EAF and ladle working linings. Within each series the grade is set by how much large-crystal fused magnesia goes into the aggregate.

Technical datasheets on request. Chemistry, physical properties and the recommended grade for each zone are sent with our offer. Shapes are pressed to your lining drawings.
Request datasheetsEvery brick carries one Thyme code: family, nominal MgO, carbon, the vessel it is made for, and its grade from A (top) to D. AOX is grade B with antioxidants. The same code runs through offers, datasheets, delivery documents and brick markings.
AMC bricks
Resin-bonded bricks built on bauxite and corundum with fused magnesia and graphite. In service the alumina and magnesia react to form spinel; the slight expansion closes joints and gives high resistance to erosion and impact at the ladle bottom.
AMC series for ladles
Bottom, impact pad and lower wall.| AAMC89C6L-A | BAMC87C6L-B | CAMC86C6L-C | DAMC80C6L-D | |

Technical datasheets on request. Chemistry, physical properties and the recommended grade for each zone are sent with our offer. Shapes are pressed to your lining drawings.
Request datasheetsFlow control
Functional refractories that control how steel leaves the furnace, the ladle and the tundish. They take the highest thermal shock and erosion in the shop, so material choice and dimensional accuracy matter more than anywhere else in the lining.
Slide gate plates
Top and bottom plates for ladle slide gate systems, resin-bonded and impregnated for wear and thermal-shock resistance at the bore.
AGC85C6LNozzles, well blocks and purging plugs
Upper and lower nozzles, well blocks and porous or slit purging plugs for argon stirring.
A95LTundish metering nozzles
Nozzle body with a zirconia insert that holds the bore and the casting rate stable over long sequences.
FA81T + Z95TEBT tap-hole set
End block, sleeve and surround blocks for eccentric bottom tapping.

Request datasheetsThe network behind every brick
Since 1990 we have traded refractory raw materials with miners and producers in China, India and elsewhere, on controlled purchase arrangements and fixed offtakes with our own oversight of production. The same aggregates go into our bricks, and we supply them to brick and castable makers worldwide.
What we supply
Aluminas, aluminosilicates, magnesia, silica and carbidesImport, export and stock on four trade hubs
We import and export across China, the EU, India and Turkey. Customers draw against stock instead of waiting on a vessel.
