Embodiment Construction

[0019] Such as figure 1 As shown, the heater arrangement structure for improving the temperature distribution uniformity of the melt in the aluminum isothermal melting furnace is provided with a partition wall 2 in the middle of the hearth of the isothermal melting furnace, and the partition wall 2 divides the hearth into a melting zone 1 and a heating zone 3. Area 3 is non-uniformly arranged with heaters 4. The heaters 4 are submerged gas heaters or submerged electric heaters. The heaters 4 are arranged in parallel between the partition wall 2 and the opposite furnace wall, and the number increases row by row. Increase by 1 respectively, the distance between adjacent heaters in each row is equal, the distance between rows is equal, and the heaters form a staggered arrangement. An aluminum liquid circulation pump 5 is arranged outside the isothermal melting furnace, the inlet of the aluminum liquid circulation pump 5 is connected to the heating zone 3, and the outlet of the al...

Abstract

The invention relates to a heater arrangement structure for improving the temperature distribution uniformity of the melt of an aluminium isothermal smelting furnace. The middle position of the furnace of the isothermal smelting furnace is provided with a partition; the partition divides the furnace into a melting area and a heating area, wherein the heating area is unevenly arranged with heaters; the heaters are arranged in parallel between the partition and the opposite furnace wall; the number of the heaters is increased row by row by one respectively; the space between the adjacent heaters of each row is equal; the space between the rows is equal; and the heaters are in staggered arrangement. The arrangement mode of the heaters can effectively eliminate the phenomenon of the temperature distribution uniformity of the aluminium melt of the heating area, improve the isothermal smelting effect, reduce the oxidation burning loss in the smelting process and improve the quality of the melt.

Description

technical field [0001] The invention relates to a heater arrangement method of an aluminum isothermal smelting furnace, in particular to a heater arrangement structure for improving the temperature distribution uniformity of a melt in an aluminum isothermal smelting furnace, and belongs to the technical field of metal smelting. Background technique [0002] Isothermal smelting technology is a new type of smelting technology with high efficiency, energy saving and environmental protection. Compared with the traditional flame reflection smelting technology, the isothermal smelting technology has outstanding advantages such as energy saving, low pollutant emission, low metal melting loss, and high melt quality. The isothermal smelting technology melts the charge at a constant temperature. The temperature of the aluminum melt in the hearth of the isothermal smelting furnace varies within a small range, and the temperature is almost the same everywhere, without forming a temperat...
