How to charge for the insulation material of aluminum factory, asbestos free calcium silicate board with a thickness of 48mm? Calcium silicate board plays a versatile role in aluminum plants. It is not only an insulation material, but also a key structural material to ensure the safe transportation of aluminum liquid and the stable operation of electrolytic cells. According to the working conditions in different areas of the aluminum plant, such as the electrolysis workshop and the melting and casting workshop, calcium silicate boards are mainly divided into two categories: insulation type and high-density non stick aluminum type. 48mm asbestos free calcium silicate board is mainly used in the following areas of aluminum plants:
Bottom insulation layer of electrolytic cell: high temperature resistance requirement, it is recommended to choose 1050 ℃ high temperature type (density 220-270kg/m ³)
Furnace pit and furnace mouth insulation layer: For medium and low temperature areas, choose the 650 ℃ type (density 170-220kg/m ³)
Aluminum liquid flow channel/distributor backing: requires resistance to aluminum liquid infiltration, can choose high-purity type (density above 800kg/m ³)
Thickness selection suggestion: 48mm is a medium to thick specification in aluminum plant insulation, with insulation effect better than 30mm and slightly thinner than 50mm, making it a cost-effective choice. If higher insulation effect is required, it is recommended to choose 50mm; if space is limited, 40mm can be selected.
1. Excellent thermal insulation (energy-saving and consumption reducing)
2. Non stick aluminum characteristic (key feature)
3. High temperature resistance and thermal shock resistance (structural stability)
4. Corrosion resistance and insulation (safety protection)
The cost of asbestos free calcium silicate board (thickness 48mm) for aluminum plant insulation is an industrial grade customized specification, sometimes priced by square meters, cubic meters, or blocks. Calcium silicate board (especially asbestos free, high-density, high temperature resistant) is a core insulation and refractory material in aluminum plants because it does not absorb aluminum water, does not pollute aluminum liquid, has high strength, high temperature resistance, and is not easy to pulverize. It is very suitable for working conditions such as electrolytic aluminum, molten aluminum, casting and rolling, and waste heat recovery.
