Continuous Casting Submerged Entry Nozzle

Erosion Resistance Submerged Entry Nozzle

Submerged Entry Nozzle

Laurel submerged entry nozzle is one of the core components in the continuous casting process. It is like a "precision navigator" for the flow of molten steel and plays a crucial role in ensuring the smooth and efficient progress of the continuous casting process. Its unique submerged design allows the tip of the nozzle to be directly immersed in the molten steel. This not only effectively prevents the secondary oxidation of the molten steel but also accurately guides the molten steel to flow evenly and stably into the mold, ensuring uniform heat distribution during the solidification of the casting billet and avoiding local overheating or undercooling phenomena. Thus, it improves the quality of the casting billet. Moreover, the shape and size of the submerged entry nozzle can be flexibly customized according to different continuous casting process requirements. Whether it is for producing thin slab, medium-thick slab or special alloy steel billets, it can be perfectly adapted to escort the stable production of high-quality casting billets in the steel industry.

Product Details

The submerged entry nozzle features the following product characteristics:

High - temperature Resistance

During the continuous casting process, the molten steel is extremely hot. The submerged entry nozzle is made of high - quality refractory materials, which enables it to withstand high temperatures without softening or melting. It maintains a stable shape and structure, ensuring normal operation throughout the continuous casting process.

Strong Erosion Resistance

Molten steel is highly corrosive chemically, and it scours the inner wall of the nozzle as it flows. Through optimized material formulations and production processes, the submerged entry nozzle has excellent erosion - resistant properties. It can resist the corrosion and scouring of molten steel, reduce nozzle wear, extend its service life, and cut down production costs.

Good Thermal Insulation

To ensure the temperature stability of molten steel during pouring, the submerged entry nozzle needs to have certain thermal insulation performance. It can reduce the heat loss of molten steel, preventing problems such as poor fluidity and uneven solidification caused by low molten - steel temperature, which is conducive to improving the quality of casting billets.

Precise Flow - guiding

The submerged entry nozzle is designed to precisely guide the molten steel into the mold. Its internal flow channel is rationally designed, allowing the molten steel to flow out evenly and stably in a predetermined direction and at a set speed. This ensures the proper distribution of molten steel in the mold, facilitating the solidification and formation of casting billets and reducing billet defects.

High Air - tightness

In the continuous casting process, it is necessary to prevent air from entering the molten steel to avoid secondary oxidation. The submerged entry nozzle has good air - tightness, effectively blocking the contact between air and molten steel, improving the purity of molten steel, and thus enhancing the quality of casting billets.
