Siam Refractory provides tailored refractory products and solutions, including both hot and cold application methods of dry tundish coating materials, available in olivine- and magnesia-based formulations.

Our flagship product, DYRACOAT®, is a high-performance dry tundish coating and working lining material, formulated with high-purity magnesia and a resin-based binder. With its high MgO content, DYRACOAT® functions as a non-reactive working lining and is compatible with all steelmaking processes.

DYRACOAT® offers significant advantages over conventional wet spraying mass, making it an ideal choice for modern tundish operations: 

• Clean, fast, and straightforward installation 
• Easy to handle and apply 
• Water-free application, eliminating risks of spalling or explosion caused by moisture evaporation 
• Prevents steel pinhole defects linked to residual moisture 
• Low energy consumption during preheating; requires shorter preheating time and is ready for cold tundish use (with preheating nozzles) 
• Enables consistent and minimal wall thickness through the use of a former
