B-type riser sleeves are compact, cylindrical-shaped auxiliary components used in steel casting. Made from low-density, highly refractory materials, these sleeves provide low thermal conductivity, allowing them to retain heat effectively. Available in various forms such as open-ended, domed, and blind versions, these feeder sleeves are suitable for casting steel with volumes up to 2140 cc.
When molten metal begins to solidify too quickly, the riser sleeve enhances thermal retention, countering rapid cooling and reducing the risks of shrinkage, cavities, or slag formation in the steel casting.
Advantages of SEFU’s B-type feeder sleeves:
- Low thermal conductivity and superior thermal insulation.
- Simplified removal post-casting through techniques such as hammering—eliminating the need for grinding and cleaning.
- Prevention of local cracks and casting defects during gas-cutting.
- Minimal air volume and controlled breathability.
Application
- Steel Casting: Engine blocks, gears, and structural parts
- Iron Foundries: Pipes and automotive components
- Industrial Components: Valves and turbine blades
- Steel Alloys: Aerospace and chemical industry equipment requiring high-temperature casting
Features & Benefits
SEFU’s vacuum-formed exothermic sleeves are tailored to enhance the solidification of molten metal, helping to prevent shrinkage defects and cavities that could lead to additional processing work.
- Solid thermal insulation prevents the casting materials from experiencing a chilling effect. It helps maintain consistent thermal retention during the casting process.
- B-Type sleeves are available in various shapes and sizes to accommodate small to moderate casting requirements.
- High refractoriness ensures that the sleeves resist expansion or deformation at elevated temperatures.
- The fire-resistant properties of the riser enable it to withstand extreme temperatures ranging from 1400 to 1600°C. It is crucial for continuous metal feeding and preventing premature solidification.
- It provides high shrinkage efficiency
