Suitable for large steel castings with circular waist, spherical, and composite insulation riser sleeves.

Performance index 

1. Density: 0.80g/cm ³~ 0.95g/cm ³;

2. Moisture content ≤ 2.0%, natural storage for one month cannot exceed 2.5% moisture content;

3. Thermal conductivity: When the hot surface temperature is 900 ° C, the thermal conductivity is ≤ 0.18w/m.k;

When the hot surface temperature is 1100 ℃, the thermal conductivity is ≤ 0.22w/m.k;

Product advantages

1. Low thermal conductivity and good insulation effect;

2. Resistant to high temperature erosion, the riser cannot sit down and always maintains a certain pressure head;

3. After the casting is unboxed, the outer wall of the riser sleeve is not sintered and is easy to cut;

4. The riser sleeve has high strength, regular shape, and is easy to use;

5. Low gas generation and good breathability
