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.

What are the core functional effects of asbestos free calcium silicate board?

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.

300 body density calcium silicate irregular parts

300 body density calcium silicate irregular parts? Calcium silicate shaped parts are non-standard and irregular shaped insulation products made of calcium silicate (an inorganic material generated by high-temperature and high-pressure reactions of quartz sand, lime, reinforced fibers, etc.) as the substrate, and pressed, cut or carved by professional molds. Calcium silicate shaped products with a bulk density of 300 kg/m ³ are widely used in high-temperature insulation, fire prevention, thermal insulation and other fields.

Hard calcium silicate for insulation materials

Hard calcium silicate for insulation materials in the non-ferrous metal industry

Is hard calcium silicate used as insulation material in the non-ferrous metal industry? In the non-ferrous metal industry (such as aluminum, copper, lead, zinc smelting and processing), high-temperature equipment (melting furnaces, insulation furnaces, flow channels, electrolytic cells, etc.) have extremely strict requirements for insulation materials: high temperature resistance, low thermal conductivity, resistance to metal melt erosion, no pollution of metal liquid, and environmental friendliness and non toxicity. In the non-ferrous metal industry, hard calcium silicate, as an insulation material, has core advantages such as high temperature resistance, low thermal conductivity, high stability, long service life, environmental protection and safety. It can effectively improve equipment energy efficiency, reduce maintenance costs and ensure safe production.
