Problems solved by technology
The advantages of the crucible melting furnace are less investment and greater flexibility, but the disadvantages are slow heating rate and low production capacity
The advantages of induction melting furnace are fast heating speed and strong stirring effect, which are suitable for alloys with high melting temperature and no need for refining. The disadvantage is that the power factor is low, auxiliary electromagnetic equipment is required, and the unit power consumption is high. The temperature difference is large, and it can bear the erosion of aluminum melt, the erosion of slag and melt, so the service life is short

Embodiment Construction
[0027] Aluminum and aluminum alloy isothermal smelting is to smelt aluminum and aluminum alloy at a constant temperature, so that the temperature of the molten aluminum in the furnace changes within a small range, and the temperature is almost the same everywhere, and the temperature of the molten aluminum in the molten aluminum pool is changed by The computer automatically monitors and controls the temperature in a small amount through the partition wall in the middle of the furnace. The isothermal smelting process is a continuous process. The molten aluminum circulates in a completely closed system, which consists of a feeding area, a furnace melting area, a heating area, and a circulating pumping area. However, the present invention provides a novel aluminum and aluminum alloy isothermal smelting furnace, which can efficiently smelt aluminum and aluminum alloy scrap, aluminum chips and primary aluminum ingots, effectively improve energy utilization, reduce the oxidation and ...

The invention relates to an aluminum and aluminum alloy isothermal smelting furnace, comprising a furnace body and an inner liner. The inner liner is arranged in the furnace body to form a hearth. Themiddle position of the hearth is provided with a partition for dividing the hearth into a furnace starting smelting zone and a heating zone. A furnace door and a furnace starting burning system are mounted on the side wall of the furnace starting smelting zone. An immersion heater is mounted on the furnace top of the heating zone and perpendicularly extends into the hearth of the heating zone. Aheadpiece is arranged on the side wall of the heating zone. A heating piece is installed on the partition. Holes are arranged on the bottom of the partition to communicate the furnace staring smeltingzone and the heating zone. A vortex feed well and a recycle pump are distributed outside the furnace body. The vortex feed well and the hearth of the furnace starting smelting zone are communicated.The inlet of the recycle pump and the hearth of the heating zone are communicated. The outlet of the recycle pump is communicated with the vortex feed well. The isothermal smelting furnace can effectively smelt the aluminum and aluminum alloy waste materials, aluminum bits and original aluminum ingots, improves the energy resource utilization ratio, decreases the aluminum liquid oxidation and burning, improves the aluminum liquid quality and optimizes the smelting art.
Description
technical field [0001] The invention relates to an isothermal melting furnace, in particular to an isothermal melting furnace for aluminum and aluminum alloys in the aluminum smelting industry, and belongs to the technical field of metal smelting. Background technique [0002] At present, the most widely used aluminum melting industry at home and abroad is the reflective melting furnace, followed by induction melting furnace and crucible melting furnace, of which the reflective melting furnace accounts for the vast majority. [0003] Reflective melting furnaces are divided into flame reflective melting furnaces and resistance reflective melting furnaces. Flame reflective melting furnaces use high-temperature flames to heat and melt furnace materials through furnace top radiation and direct flame radiation. Now most of them use liquid or gaseous fuels, flame The temperature can reach 1600 ~ 1700 ℃. The advantages of the flame reflection melting furnace are large production c...
