It can be judged whether the coated sand meets some characteristics by detecting the index of the coated sand

By detecting the index of the coated sand, it can be judged whether the coated sand meets the characteristics of bending resistance, compression resistance and high temperature resistance. The required indicators are: normal temperature flexural strength, thermal flexural strength, burning loss, particle size and melting point. Optional detection indicators are: tensile strength at room temperature, tensile strength in hot state, gas volume and fluidity.

1. Heat-resistant time—test whether the coated sand core can maintain its strength at 700-1500 ° C under high temperature without deformation and disintegration.

2. High-temperature compressive strength—Simulate the actual conditions of casting and test the compressive strength of the coated sand core at 1000-1500 ℃.

3. Shelling resistance-test the shelling resistance of the coated sand.

The above are the indicators for detecting coated sand, using trapped coated sand detection equipment, such as high temperature performance tester, gas generator, thermal strength tester and other equipment.
