Calcium silicate insulation board is an inorganic insulation material with high strength and stable performance, which is made of calcium material, siliceous material and reinforcing fiber as main materials, and is made by flow forming, slab compaction and autoclave curing. It has high strength, low thermal conductivity, high temperature resistance, corrosion resistance, and it is cuttable. It is widely used in power, metallurgy, petrochemical and other fields of equipment.
High temperature resistant calcium silicate insulation board has great advantages when being used in aluminum reduction cells. Aluminum reduction cell is one of the main equipment of aluminum industrial enterprises, and their thermal efficiency is only 20%. The application of calcium silicate board completely solves the problems of tight energy supply, how to reduce production energy consumption and improve comprehensive energy utilization.
From the perspective of construction technology, the calcium silicate insulation board is packed in cartons so damage to the calcium silicate board is small. Calcium silicate insulation board’s shape is neat and its size tolerance is small. It is practical and economical to use calcium silicate insulation board instead of diatomaceous earth brick to transform aluminum reduction cell. Use calcium silicate insulation board for the insulation of aluminum reduction cells can greatly save economic expenditure. From the point of view of production operation, it can significantly reduce furnace shut down caused by bottom leakage due to the use of diatomaceous earth brick. And using calcium silicate insulation board in aluminum reduction cells has obvious effect of energy saving and consumption reduction.
In summary, the use of calcium silicate insulation board is reasonable from the perspective of process, construction and function.
