The choice of ladle refractories directly affects operational safety, plant life and steel quality. Sidertrading offers complete, customised solutions, designed in Italy and made from high-performance European refractory materials.
Top products include:
- Plates for Slide Gates: SID-PLATES guarantee high thermo-mechanical performance, resistance to corrosion and thermal shockI ideal for SIDER GATES.
- Ladle Bricks: made from carefully selected materials according to the different requirements of the areas of the structure. For the walls and bottoms, SID-MAG is used, a magnesite-based material, available in both cast and sintered form, which guarantees high strength. In the area subject to the most aggressive slag action, known as the “slag zone”, materials with a high carbon content are preferred, offering superior strength. The impact area, on the other hand, is protected with bricks made of a combination of alumina, MgO and carbon, to better absorb mechanical and thermal energy. Finally, refractory materials such as calcined bauxite or andalusite are used for the permanent lining, which ensure long life and good heat resistance.
- Purging Plugs: porous, directional and dynamic SID-PLUG.
- Well Blocks and Nozzle: low porosity and high density for maximum reliability.
How to choose the best refractory?
Based on steel composition, operating temperature and casting frequency. High-impact areas require higher erosion resistance, while areas exposed to slag need refractories with high carbon content.
Sidertrading assists customers with technical support, customised design and rigorous quality control, ensuring tailor-made solutions for every steelmaking requirement.
