Simpson conducted an experiment testing the resistance of surface coating on three different plows. The first plow had a ceramic covered face surface, the second plow was made with special abrasive resistance alloy coating and the third was a standard carbide plow. All three plows ran 24 hours a day, 5 days a week for 8 months. At the conclusion of the experiment the end result was this: The carbide/ceramic plows showed a higher wear resistance rate against sand and will stay in operation longer.
The standard plow is not as durable as ceramic material since carbide is only located on the bottom radius and back side of the plow.
The Difference between Carbide/Ceramic and Carbide Plows:
- The carbide/ceramic plows have special high abrasion resistant surfaces that allow the sand to slide over the plow for better mulling. When correctly and regularly adjusted, they will have a long service life.
- Whereas, Carbide plows, only has carbide on the bottom radius and back side. With this application, you will get a ripple effect on the face of the Carbide plow, and it will wear much faster.
For better mulling and less downtime foundries worldwide use the carbide/ceramic plows on the Simpson Speedmullor.
