Background

The bottom of a common aluminum melting furnace consists of a working layer, an impermeable layer and a heat-insulating layer, and the performance and the construction mode of the working layer are particularly important because the working layer is directly contacted with high-temperature aluminum liquid. The conventional furnace bottom working layer material is constructed by high-alumina bricks or castable, but the high-alumina bricks are time-consuming and labor-consuming in building due to small volume, high hardness and fixed shape, and the joints of corners and other parts need to be cut, so that the castable construction is more convenient and reliable.

In addition, the traditional casting material construction needs to be carried out by supporting a mold in blocks for casting, the rest part is continuously cast after the part cast first is solidified in the next day, the mold support occupies a large part of time, casting needs to be carried out in at least 2 days, and the construction period is relatively fixed; and the later stage is toasted by interior and is heated unevenly outward, and intensity also distributes unevenly, along with daily use working layer by interior and outer wearing and tearing gradually, life will further shorten, consequently the big brick of pouring that a melting stove bottom was used is needed now urgently to solve above-mentioned problem that appears.
