Removing Scale from Steel/Cast Iron with Ultrasonic Cleaning
Removing scale from steel and cast iron is an important process in many industries, as the presence of scale can negatively affect the performance and durability of components. One effective method of removing scale from these materials is through ultrasonic cleaning, which utilises high-frequency sound waves to generate microscopic bubbles that gently remove contaminants. Ultrasonic cleaning is an effective method for removing scale, and the use of the Rodastel 30 cleaning detergent, along with the appropriate equipment, can help to ensure that components are free from all contamination. By following the process outlined below, it is possible to achieve high-quality results when removing scale from steel or cast iron, resulting in components that are more durable and perform better.

Process for removing Scale from Steel/Cast Iron
The first step in removing scale from steel or cast iron is to choose the appropriate cleaning detergent. For this process, Rodastel 30 was selected due to its effectiveness in removing both scale and oxidation. The tank was then filled with a 5% concentration of the detergent and allowed to reach the required temperature of 45°C while degassing. The parts were then submerged in the solution for a period of 20 minutes. During this time, the ultrasonic cleaning process was initiated, causing microscopic bubbles to form and remove the scale and oxidation from the surface of the components.
Once the cleaning cycle was complete, the parts were rinsed in tap water for two minutes. This step is important in order to remove any residual cleaning solution and to prepare the parts for the next stage of the cleaning process. To ensure that any minerals which may cause staining were removed, the parts were then rinsed in DI water for an additional two minutes. Finally, the parts were dried using a Versa hot air dryer for five minutes at a temperature of 70°C.
It is worth noting that a corrosion inhibitor was added to the final DI rinse in order to prevent oxidation from occurring during the drying process. This step is important in ensuring that the parts remain contamination-free once they have been cleaned.
In order to achieve the best possible results when removing scale from steel and cast iron, it is important to use the right equipment. For this process, an ultrasonic cleaner was used in combination with the Rodastel 30 cleaning detergent. The ultrasonic cleaner generates high-frequency sound waves that create microscopic bubbles in the cleaning solution. These bubbles then collapse, producing a powerful cleaning effect that removes even the toughest contaminants.
In addition to the ultrasonic cleaner, a Versa hot air dryer was used to dry the components once the cleaning process was complete. This is a critical step, as leaving the components to air-dry can result in contamination from the surrounding environment.
