A producer of large cast
steel parts (3,500-50,000 lb) for the mining, construction, marine,
rail, turbine valves and industrial markets needed to reduce escalating
media cost without affecting production quality.
For specialty application requiring high-quality metal finishing, zircon sand was used due to its high refractory value and low thermal expansion that enhanced both dimensional reproducibility and shakeout.
The increased global demand for high-quality zircon sand had made it prohibitively expensive and trials with lower-grade zircon sand proved ineffective due to cast quality issues.
Using zircon sand, the clean-up time on specialty parts could take 30-40 hours to complete, lowering output and adding costs to production.
