📌 What is the reason for stopper rise and stopper wash in tundish during continuous casting of steel? During continuous casting of steel, the stopper rise and stopper wash in the tundish can impact the casting process. Let’s explore these phenomena: 👉 Stopper Rise: Definition: Stopper rise refers to the upward movement of the tundish stopper rod during casting. 👉 Cause: The difference in thermal expansion between the body material and the metallic rod leads to the connection eventually slackening. During preheating and use, the thin graphite seal provides limited elasticity, and leaks may occur due to vibration and lateral stopper movement. 👉 Impact: Stopper rise affects the flow control of molten steel from the tundish to the mold. It can lead to variations in steel flow rates and affect the quality of the cast product. 📌 Stopper Wash: Definition: Stopper wash occurs when inclusions or impurities deposit on the tundish stopper nose during casting. 📌 Cause: As the molten steel flows through the channel between the stopper rod and the outlet, inclusions deposit on the outlet surface, narrowing the channe. 📌 Impact: Stopper wash can reduce the effective flow area, affecting the steel flow rate and potentially leading to defects in the cast product. #SteelMaking #Manufacturing #Metallurgy #MetallurgicalEngineering #tundishcar
