Suitable for small and medium-sized steel castings, alloy steel, or large cast iron castings.

performance index 

1. Density: 0.70g/cm ³~ 0.80g/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 ≤ 0.16w/m.k;

When the hot surface temperature is 1100 ℃, the thermal conductivity is ≤ 0.20w/m.k;

Product advantages

1. Low thermal conductivity and good insulation effect;

2. Mechanical hammering can be used to remove the riser sleeve, reducing the workload of polishing and cleaning the riser sleeve;

3. Avoid local cracks and casting shedding caused by gas cutting at the root of the coarse riser sleeve of the casting;

4. It is beneficial to avoid hot spots at the root of the riser sleeve and improve the mechanical properties of the casting.
