ANJF-300B heating insulation board
About:
ANJF-300B heating flexible insulation board is made of a variety of raw materials through a specific process, with medium-strong heating, excellent insulation characteristics. It is suitable for large riser of various grades of cast steel and cast iron. It is not limited by the shape and size of the riser, and can be applied to various modeling processes. The technical parameters under the supply condition are as follows:
Properties: medium strong heat, low density, to ensure that the casting solidification has excellent feeding performance.
Color: Brown gray
Density: 0.7g /cc
Features:
Selected high-quality raw materials and scientific ratio carefully made, heating strong, no chilling effect on molten steel, good thermal insulation performance.
High refractoriness, the riser can resist the hot pressing action of molten steel without large deformation. Low gas volume, good air permeability.
Perfect raw material and product testing system to ensure good product quality stability.
It can be bent and spliced into round, oval, long circle and other shapes according to the process requirements.
Good strength, can meet the resin self-hardening sand, water glass sand and other molding process requirements.
Use:
1. The modulus, the amount of feeding liquid required and the feeding distance are calculated according to the specific casting.
2. Calculate the required riser modulus, liquid volume and quantity.
3. The thickness of this product is 30 and 60 mm. Under normal circumstances, 30 mm thick products are used for risers with diameters less than 600 mm. 60mm thick products with diameters between 600-750 nm; For risers larger than 750 mm, use one layer each 30 mm and 60 mm thick. When bending and rolling the heating flexible insulation board, pay attention to the opening outward, and fill the opening slot with molding sand.
4. In the above use case, the modulus magnification (MEF) of ANJF-300B heating flexible insulation board relative to the sand riser of the same geometry is not less than 1.28.
5. Use ANJF-300B thermal flexible insulation board to surround the root of the riser to leave a cutting step, here. It is good to use special sand (such as chromite ore, zirconium sand, etc.) to make a ring sand core or use special sand modeling.
