the ladle shroud nozzle for continuous casting is also called the protective sleeve. It is an important component connecting the ladle and the tundish. It is connected to the lower shroud of the sliding shroud device at the bottom of the ladle, and the lower end extends into the tundish.

The shroud is an important functional refractory material for maintaining casting and improving steel quality. The length of the shroud is generally 600-1800mm, the pipe diameter is 90-150 mm, and the structure of the ladle shroud nozzle is shown in Figure 2. Its use conditions are harsh and must have the following functions: excellent thermal shock resistance; good mechanical strength; excellent resistance to alternating corrosion of molten steel and slag, high oxidation resistance, and in addition, other suitable properties are required for some special steel grades.more information,please check here
Slide Gate Plate is a critical component in the continuous casting process, used to control the flow of molten steel from the ladle or tundish to the crystallizer. The following is a detailed description:
Role and Function
· Flow Control: The sliding gate plate adjusts the opening size of the nozzle through the sliding mechanism, thereby controlling the flow of molten steel. This is very important for maintaining a constant and controllable casting process.
· Operational Flexibility: The sliding gate plate allows operators to adjust the molten steel flow rate as needed during the casting process to adapt to different production requirements and conditions.
· Emergency Stop: In an emergency, the sliding gate plate can completely close the flow channel and stop the flow of molten steel, thereby preventing accidents and losses.

The slide gate plate is made of sintered corundum, fused corundum, fused zirconium corundum, zirconium mullite and other main raw materials. It is combined with new resin, formed by high pressure and fired at high temperature. It has the advantages of high strength, super hard, high temperature resistance and corrosion resistance, and strong thermal stability.

Monoblock Stopper is used mainly for flow control on Molten Steel poured from tundish to mould. Monolithic Stopper is installed in the Tundish above the Sub Entry Nozzle and the gap between stopper head and Nozzle decide the throughput requirement of Molten Steel inside the Mould.
Argon can be blown into the tundish through argon inlet to prevent nozzle from Clogging ( specially designed feature wherever it is required we design and customise accordingly)
SPECIAL FEATURES:
o Facility for gas purging
o Anti oxidant properties
o Design and size as per customer’s requirement
o Clogging free casting for long sequence of casting
o Gas purging facilities to prevent alumina clogging (optional)
o Slag zone immersed part re-inforcement with special material for long life
o Argon sealing purging arrangement can be provided on customer’s request
o Wide range of formulation for withstanding oxidation and long sequence casting
o Different assembly methods for assured security even in long sequence casting
o We manufacture Silica free Oxy-bore ladle shroud for less corrosion and long sequence casting

Monoblock Stopper is used mainly for flow control on Molten Steel poured from tundish to mould. Monolithic Stopper is installed in the Tundish above the Sub Entry Nozzle and the gap between stopper head and Nozzle decide the throughput requirement of Molten Steel inside the Mould.
In modern continuous casting operations, the ladle shroud plays a critical role in ensuring smooth steel flow, minimizing re-oxidation, and stabilizing casting quality. As global steel plants increasingly rely on China for high-quality refractory components, choosing a reliable ladle shroud supplier from China has become a key factor that directly affects safety, casting stability, product quality, and overall cost efficiency.

Online 4-H Crop Production Lessons for Grades 4-8: Soil-based and Soilless Systems
Earth’s population growth and concurrent decline in farmland pose great challenges for food security across our planet.1 The challenge of how to feed 9.9 billion people calls for new methods to grow and distribute food.2 Having access to fresh and nutritious food is a basic need for all people. We invite youth to be learners and leaders who meet these challenges with a new vision for crop production that combines soil-based and soilless farming.
To engage youth in these global challenges, WVU Extension Service, Iowa State University Extension, and PLANTS, LLC have partnered to create a series of online lessons. Youth can gain a foundation by digging deep into crop growth and development in conventional and hydroponic systems. Youth learners in this online program will also explore their role and possible career opportunities in sustainable agriculture and ag technology.
Questions that students will explore in the online lessons include:
- How do plant seeds differ in terms of germination rates, structures, and plant types?
- What type of plant maintenance is important for each stage of plant growth?
- How does light intensity and duration affect photosynthesis?
- What are key elements of a healthy soil, and how does soil quality affect plant growth?
- When are soilless plant production systems good alternatives to soil-based farming?
- What plant growth strategies can be used to conserve water?
- How can farmers apply new plant growth technologies to increase crop yield and integrate sustainable agricultural practices?
This project is made possible by support from NASA West Virginia Space Grant Consortium. Students will explore soil-based as well as soilless (hydroponic) agriculture methods used locally and as part of NASA space science research. The Iowa State University 4-H program shared material from their Crops Feed the World online lessons in support of this project.
