Monolithic Stopper Rod_Continuous Casting Stopper Rod

Integral Stopper Rod

Laurel Integral Stopper Rod, as a crucial component in the continuous casting process, plays an extremely vital role. It is usually fabricated from materials with high temperature resistance, erosion resistance and excellent thermal stability, to withstand the high-temperature scouring and chemical erosion of molten steel. The monolithic design renders its structure compact and coherent. Compared with split components, it effectively averts the risks of loosening and molten steel leakage at the connections, ensuring the accuracy and stability of molten steel flow control. The shape of its head is meticulously designed and can be flexibly adjusted according to different continuous casting requirements. When opened, it allows the molten steel to flow out smoothly; when closed, it blocks tightly, precisely regulating the flow rate and direction of the molten steel, guaranteeing the continuous and efficient progress of the continuous casting process and making great contributions to the production of high-quality and uniformly sized casting billets.

Product Details

The Integral Stopper Rod comes with the following characteristics:

1. High Temperature Resistance

It is typically crafted from top - grade high - temperature. This enables it to withstand the high temperatures of molten steel during the continuous casting process. ensuring stable shape and performance in a long - term high - temperature environment.

2. Strong Erosion Resistance

As the stopper rod comes into direct contact with molten steel, it must possess excellent erosion resistance. Its material can resist the chemical corrosion and mechanical scouring of molten steel and slag. This guarantees the service life of the stopper rod, reduces the replacement frequency caused by erosion, and enhances the efficiency and stability of continuous casting production.

3. Good Thermal Stability

During the continuous casting process, the stopper rod experiences drastic temperature changes. Its good thermal stability allows it to withstand thermal shocks, making it less prone to cracking or spalling due to thermal stress. This ensures the structural integrity and performance reliability of the stopper rod.

4. Precise Flow Control

The head of the monolithic stopper rod is precisely designed. By cooperating with the nozzle, it can accurately control the flow of molten steel. Operators can flexibly adjust the position of the stopper rod according to the production process requirements, achieving precise regulation of the molten steel flow, thus guaranteeing the quality of the cast billet and the continuity of production.

5. High Strength and Rigidity

The stopper rod needs to remain stable under the static pressure and flowing impact force of molten steel. Therefore, it has high strength and rigidity. This allows the stopper rod to withstand large external forces without bending or breaking, ensuring normal operation during the continuous casting process and maintaining a stable flow of molten steel.

6. Overall Structural Reliability

The monolithic design eliminates potential problems such as loosening at the connection parts and molten steel leakage that may occur with split - type stopper rods. It enhances the overall reliability and sealing performance of the stopper rod. This structure can better meet the requirements of the continuous casting process and reduces production accidents and quality issues caused by stopper rod failures.
