Reduce the quantity of materials destined to landfill increasing the shares of unshaped in the steelmaking application. Solutions for steel ladle such as monolithic sidewall or maintenance with continuous applications of shotcrete increase the life cycle of the steel ladles and reduce the number of repairs, reducing also the quantity of bricks that have to be disposed in the landfill.
The trials conducted on monolithic ladles have shown that with a combined technology of monolithic sidewall and sequential shotcrete repairs the performance (measured in number of heats) can be doubled.
There are also advantages when it comes to waste reduction and recycling.
2 main features show the benefits of monolithic lining for steel production:
✔ Extension of ladle campaign reducing the quantity of sets of bricks for relining
✔ Reduction of the waste connected to the demolition of the ladle and the end of the campaign
✔ The portion of the lining that hasn’t worked will be kept as backbone for the new material to be casted on top of it
✔ Reduction of CO2 emission related to heating up of steel ladle after each campaign, using carbon-free refractory materials (based on pure Al2O3 and Spinel)
