At INSERTEC, we continue to develop refractory solutions that enhance plant efficiency while ensuring high steel quality. MAPATCH is a high-performance sacrificial mass, formulated with over 90% MgO, specifically designed for use in steel ladles.
Key Advantages of MAPATCH:
- Easy to apply, streamlining maintenance operations.
- Compatible with neutral and basic slags, making it a versatile choice.
- Minimizes non-metallic inclusions, contributing to cleaner steel.
- Easily demolished after use, thanks to controlled shrinkage that also simplifies ladle cleaning.
- Provides some thermal insulation, helping to preserve metal temperature.
- Serves as an effective sacrificial layer in steel ladles, protecting the permanent lining.
What makes it interesting?
While the ladle is hot, MAPATCH 90 remains stable and functional in the working area. But once the ladle cools down, the material tends to self-collapse, making its removal extremely easy and efficient — often without the need for mechanical tools.
This behavior allows for the renewal of the sacrificial layer after each cooling cycle, meaning that every casting starts with a completely clean ladle. The result: reduced risk of steel contamination and significantly lower slag carryover.
MAPATCH not only protects the ladle but also improves process efficiency and end-product quality. A smart, practical, and reliable solution designed for the real demands of the steel industry.
