Beta Steel’s caster roll out table experienced broken anchor bolts and failed grout due to the vibration caused by the lack of hold down pressure from the bolts. Since the maintenance shutdown time for these repairs was short, the repairs had to be completed quickly. UltraFlow 4000/8 was chosen for it's rapid strength gain.
During the course of normal operations at Ispat-Inland Steel’s mill, several sections of the 64" hot strip discharge table came loose due to broken anchor bolts and failed grout. Due to the short down time, a conventional precision grout could not be used. UltraFlow 4000/8 precision grout was recommended.
The base for this equipment measured 6 feet by 2 feet 3 inches and the grout was to be 3 inches thick. UltraFlow easily provided enough working time and flowability to be placed under the plate and still reach the required strength of 4000 psi in the short 8 hour window that remained for the project. Product used was UltraFlow 4000/8.
Graycor Project Superintendent said, "The grout was easy to install and flowed under the fan base plate better than expected. The switch to UltraFlow helped to get this phase of the project back on track and completed on time." Product used was UltraFlow 4000/8.
