CCEWOOL® Ceramic fiber hearth board is produced by ceramic fiber bulk and binding agents. The board is hard and tough, has excellent self- anchorage force and compressive strength, can effectively resist the impact of the molten metal. CCEWOOL® ceramic fiber hearth board is one high-strength fiber board which compressive strength property is 10 times than normal ceramic fiber board.
Stable Product Quality
Strict control of raw materials
Control impurity content, ensure low thermal shrinkage, and improve heat resistance
1. Ceramic fiber boards are manufactured with self-manufacturing ceramic fiber bulk, which offers stable quality.
2. Self owned raw material base, material inspection before entering factory, computer-controlled ingredient proportion system, strictly control raw material purity, therefore, manufactured ceramic fiber blanket’s shot content is 10%, which is 5% lower than similar products. Thermal conductivity reaches 0.12W/m.k and thermal shrinkage is lower than 2%.
3. Through strict control at each step, we reduce the impurity content of the raw materials to less than 1%. The CCEWOOL ceramic fiber boards we produce are pure white. The quality is more stable, and the service life is longer.
Production process control
Reduce the content of slag balls, ensure low thermal conductivity, and improve thermal insulation performance
1. The fully automatic ceramic fiber production line of super large boards can produce large-size ceramic fiber boards with a specification of 1.2x2.4m.
2. The CCEWOOL ceramic fiberboard production line has a fully automatic drying system, which can make drying quicker and more thorough. The deep drying is even and can be completed in 2 hours. The products have good dryness and quality with compressive and flexural strengths over 0.5MPa.
3. CCEWOOL Ceramic fiber hearth board is hard and tough,has excellent self- anchorage force and compressive strength,can effectively resist the impact of the molten metal.CCEWOOL ceramic fiber hearth board is one high-strength fiber board which compressive strength property is 10 times better than normal ceramic fiber board.
4. The products produced by the fully automatic ceramic fiber board production lines are more stable than the ceramic fiber boards produced by the traditional vacuum forming process. They have good flatness and accurate sizes with the error +0.5mm.
5. CCEWOOL ceramic fiber boards can be cut and processed at will, and the construction is very convenient. They can be made into both organic ceramic fiber boards and inorganic ceramic fiber boards.
Ensure bulk density and improve thermal insulation performance
1. Each shipment has a dedicated quality inspector, and a test report is provided prior to the departure of products from the factory to ensure the export quality of each shipment of CCEWOOL.
2. A third-party inspection (such as SGS, BV, etc.) is accepted.
3. Production is strictly in accordance with ISO9000 quality management system certification.
4. Products are weighed before packaging to ensure that the actual weight of a single roll is greater than the theoretical weight.
5. The outer packaging of each carton is made of five layers of kraft paper, and the inner packaging is a plastic bag, suitable for long-distance transportation.
