70 K Mortar
70 K Mortar is a high-alumina, heat-setting refractory mortar specifically formulated for jointing and bedding applications within flow control refractory assemblies and ladle lining systems operating at continuous service temperatures up to 1,600°C. The “70 K” designation reflects its 70% alumina content, placing it firmly in the high-performance mortar category where standard fire clay mortars would fail under the combined thermal and chemical stresses of molten steel contact. Imperial World Trade supplies 70 K Mortar as a precision bonding solution for steel plant refractory contractors who demand consistent chemistry and reliable joint strength in every casting sequence.
- 70% Al₂O₃ Content: High alumina chemistry ensures compatibility with high alumina bricks and flow control refractory components in ladle and tundish systems.
- Heat Setting Bond: Develops full mechanical and chemical strength only upon reaching operating temperature, accommodating natural thermal expansion during heat-up without joint cracking.
- Slag Resistance: Alumina-rich composition resists chemical attack from basic and neutral ladle slags encountered during steel refining operations.
- Thin Joint Application: Optimized particle fineness allows consistent application at 1-2mm joint thickness for precise refractory assembly work.
- High Refractoriness: Maintains joint integrity and load-bearing capacity at continuous service temperatures up to 1,600°C.
- Batch Consistency: Tightly controlled raw material selection ensures chemical and physical uniformity across every production batch supplied.
Imperial World Trade supplies 70 K Mortar with full chemical analysis and refractoriness data, giving steel plant refractory teams the technical confidence to specify it for critical ladle and flow control jointing applications.
