Description

Technical Field

[0001] The utility model belongs to the technical field of molten aluminum transportation and relates to a preheating device for a molten aluminum transportation tank. Background Art

[0002] Molten aluminum, as the name suggests, is the liquid after aluminum products are melted at high temperature. In the process of casting aluminum products, the molten aluminum needs to be transported, which requires the use of a molten aluminum transportation device. The existing molten aluminum transportation devices mostly use molten aluminum transportation tanks for transportation. Before loading the molten aluminum, the existing molten aluminum transportation tanks need to be preheated.

[0003] Existing molten aluminum transport tanks often ignore the preheating step before loading molten aluminum. If the molten aluminum transport tank is not preheated, the tank body will be heated unevenly, which may easily cause potential damage to the molten aluminum transport tank and shorten its service life. At the same time, preheating the molten aluminum transport tank can increase the insulation effect of the molten aluminum and extend the insulation time. Existing preheating devices often use combustible gas for heating, which is cumbersome to operate and easily leaves other substances inside the molten aluminum transport tank. Therefore, we propose a simple-to-operate preheating device for molten aluminum transport tanks. Utility Model Content
