Common Corrosion Problems in Electrolytic Aluminum Tanks

In the electrolytic aluminum production process, aluminum tanks face a series of challenges. Fluoride and cryolite in the electrolytic environment corrode the tank lining, and the high - temperature molten aluminum wets the inner surface. These issues lead to a short lifespan of the aluminum tank, high energy consumption, and large maintenance costs. Data shows that the average lifespan of ordinary aluminum tanks ranges from 3 to 5 years, with high maintenance frequencies. The electricity consumption per ton of aluminum produced is relatively high, placing a heavy burden on enterprises' cost control and production efficiency improvement.

Characteristics of Vermiculite Insulation Boards

Core Raw Materials and Temperature Resistance

Vermiculite insulation boards are made from unique core raw materials. Through a high - temperature purification process, these boards can tolerate extreme environments up to 1050°C. At high temperatures, its strength increases, and the thermal conductivity decreases. For example, after reaching 1000°C, the thermal conductivity can decrease by about 30% compared to the initial value, which has significant advantages for energy - saving in high - temperature environments.

Anti - corrosion and Non - wetting Properties

Vermiculite insulation boards have excellent anti - fluoride and anti - cryolite erosion capabilities. They can effectively resist the chemical corrosion caused by these substances in the electrolytic aluminum environment. Moreover, they are not wetted by molten aluminum, which maintains the integrity of the tank lining and improves the structural stability of the aluminum tank.

Data Comparison of Before - and - After Use

By comparing the data before and after using vermiculite insulation boards, significant improvements can be observed. The lifespan of aluminum tanks can be extended to over 10 years, which is more than twice the original lifespan. The maintenance frequency has decreased by about 30%. Meanwhile, the electricity consumption per ton of aluminum has decreased by approximately 15%, which greatly reduces the production cost of enterprises.

Typical Success Cases

Many aluminum enterprises have achieved remarkable results after adopting vermiculite insulation boards. For instance, a large - scale aluminum enterprise in the United States extended the lifespan of its aluminum tanks from 4 years to 12 years after using vermiculite insulation boards. Its maintenance cost was reduced by 35%, and the production energy consumption was effectively controlled. This case demonstrates the significant practical value of vermiculite insulation boards.

Comprehensive Benefits Brought by Vermiculite Insulation Boards

In summary, vermiculite insulation boards bring a series of comprehensive benefits to aluminum enterprises. By extending the equipment lifespan, it reduces the loss caused by equipment replacement and downtime. Energy - saving and consumption - reduction measures help enterprises cut production costs. Choosing vermiculite insulation boards means reducing 30% of maintenance costs and increasing the aluminum tank lifespan by more than 2 times.
