Introduction
Submerged Entry Nozzles (SEN) are an essential part of any steel-making operation. An SEN is a ceramic tube that delivers the steel to the mould during the casting process. The SEN is placed in a well where hot metal pours down through it and immerses in the steel below, allowing for a customer flow of steel through the casting. An SEN can make or break a steel-making operation. It provides the critical link between the furnace and the mould. Getting the right SEN can significantly improve the process and yield results for the steel-making operation.
Features of Submerged Entry Nozzles
Our SENs have the following features that make them stand out from the competition:
1. High-Quality Materials
We use high-quality materials in making our SENs. The ceramics we use are of the highest grade, and our SENs are precisely engineered to meet our customer's requirements.
2. Long-Lasting
Our SENs are long-lasting and can withstand high temperatures and thermal shock. The material we use is highly resistant to erosion, corrosion and can handle highly abrasive materials.
3. Precision Engineering
Our SENs are designed to provide a consistent flow of steel through the casting process. The precision required to make this happen is critical, and our engineering team ensures the highest level of accuracy.
4. Cost-Effective
Our SENs are highly cost-effective because they last longer than other SENs in the market. This makes them the ideal choice for steelmakers who want to optimize their operations.
5. Increased Yield
The use of our SENs leads to an increase in yield during the casting process. The consistent flow of steel provided by our SENs allows for a higher level of precision in casting, thereby increasing yield and reducing waste.
Benefits of Our Submerged Entry Nozzles
1. Reduced Downtime
Our SENs have a long lifespan and result in less downtime because steelmakers do not have to replace them often.
2. Increased Productivity
Our SENs provide a consistent flow of steel, leading to a more efficient and productive casting process.
3. Enhanced Quality of the Cast
The use of our SENs improves the quality of the cast by providing a consistent flow of steel and a higher level of precision during casting.
4. Increased Efficiency
Our SENs allow steelmakers to optimize the casting process, resulting in increased efficiency and higher production levels.
5. Ideal for High-Speed Casting
Our SENs are ideally suited for high-speed casting, where precision is of the utmost importance.
Conclusion
In conclusion, our Submerged Entry Nozzles are high-quality, long-lasting, precision-engineered, cost-effective, and provide increased yield, all of which makes them the ideal choice for any steel-making operation. The benefits of using our SENs include reduced downtime and increased productivity, enhanced quality of the cast, increased efficiency, and ideal for high-speed casting.

Standard
Q/L YS136-1988 Series of alumina –graphite refractory products for Con-casting
Description
These Submerged Entry Nozzles are cast refractory sleeves, which are installed at the bottom of the tundish and inserted below the mold level of the continuous steel casting equipment. Their purpose is to protect the steel from flowing from the tundish to the crystallizer, and prevent secondary oxidation and splashing of molten steel in the tundish. At the same time, they play an important role in improving slab quality, improving working conditions, stabilizing continuous casting operation and preventing slab surface defects.
Features
Our Submerged Entry Nozzles are made of high-quality steel, with good slag resistance, plugging resistance, long service life, low acidity, and can maintain its strength and appearance for a long time. They have purification properties, can prevent oxidation of molten steel and effectively prevent corrosion of molten steel. In addition, we recommend that you choose the appropriate shape of the immersion nozzle according to the size of the pouring section and the pouring speed, and can also provide you with customized services.
