The CQ200 heating flexible insulation board is made of various raw materials through specific processes, and has the characteristics of medium strength heating and excellent insulation. A large riser sleeve suitable for various grades of cast iron parts. It is not limited by the shape and size of the riser sleeve and can be applied to various molding processes. The technical parameters in the supply state are as follows

Property: Medium strength heating, low density, ensuring good shrinkage performance during casting solidification.

Color: Brown gray

Density: 0.65g/cm ³~ 0.75g/cm ³

Characteristics

1. Made with carefully selected raw materials and scientific ratios, it has a strong heating effect and does not cause quenching effect on the molten steel. It has good insulation performance.

2. High fire resistance, the riser sleeve can resist the hot pressing effect of molten steel without expanding or deforming. Low gas generation and good breathability.

3. It can be bent and spliced into circular, elliptical, or elongated shapes according to the process requirements.

4. Good strength, able to meet the requirements of molding processes such as resin self hardening sand and sodium silicate sand.

apply

1. Calculate the modulus, required amount of filling fluid, and filling distance based on specific castings

2. Calculate the required modulus, liquid volume, and quantity of the riser sleeve

3. This product has two thicknesses: 30 and 60 millimeters. Generally, a 30 millimeter thick product is used for riser sleeves with a diameter less than 600 millimeters; Use 60mm thick products with a diameter between 600.750mm; For riser sleeves larger than 750 millimeters, use one layer each of 30 and 60 millimeters thick. When bending the heating flexible insulation board, pay attention to the outward opening and fill the gap with molding sand.

4. Under the above usage conditions, the modulus amplification factor of the CQ200 heating flexible insulation board relative to the sand riser sleeve of the same geometric shape is not less than 1.28.

5. When using CQ200 heating flexible insulation board to enclose the root of the riser sleeve, a cutting step should be left. In this case, special sand (such as chromite sand mixed with sand) should be used to make a circular sand core or shaped with special sand.
