Shotcreting for steel ladles is our concept to combine the benefits of monolithic lining with those of the original brick working lining.
The repetitive application of repair layers of monolithic castable onto existing brick layers leads to unique advantages for steel makers. With shotcreting solutions by Seven Refractories, steel manufacturers benefit from increased performance and flexibility, while at the same time reducing cost. Due to the superior physical and chemical properties of this highly developed dense castable, steel ladle management has never been as easy.
Shot creting is an installation technology combining the physical properties of high-density casting materials of low, ultra-low or no cement refractories with pneumatic spray techniques.
Refractories specially developed for shotcreting technique show similar characteristics to more traditional casting mixes. However, the specific technology involved makes shotcreting outstanding in terms of time and cost reduction compared to other methods.
By minimizing the amount of water needed, even the application onto MgO-C bricks is possible. The original brick layer is maintained and works as a “safety layer”.
Shotcreting enables steel ladle management without any need for molds and additional engineering, consequently resulting in cost reduction and time saving.
Wear rates of 0,8 to 1,0 mm per heat and potentially „endless“ lining, shot creting has quickly established itself as the preferred method, resulting in up to 30% cost reduction for the steel ladle lining, while increasing performance up to 50%.
