Here is a video of our crew relining a sand silo at a foundry in July. Man, this was a hot one, with temperatures outside of nearly 100 degrees! Safety is always of the utmost importance, so staying hydrated and getting good rest between working days was pivotal.
Relining a sand silo in a foundry is the process of replacing the worn-out protective interior skin of a massive storage tower that holds mold-making sand. In a metal-casting foundry, heavy, abrasive sand is constantly loaded into and pulled out of these silos, causing intense friction that scrapes and thins the inner walls over time.
To prevent the structural metal of the tower from wearing away, rusting, or leaking, workers must completely empty and clean the silo to inspect it for structural damage. We installed a fresh, durable barrier by welding new steel plates.
This maintenance keeps the silo structurally sound, prevents dangerous wall collapses, and ensures the sand remains clean and free of rust contamination for the metal-casting process.
Enjoy!
