Aluminum and aluminum alloy isothermal smelting furnace

Abstract

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. The middle 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. A headpiece 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 smelting zone 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.

AI Technical Summary

Benefits of technology

This patented technology allows for better control over melting temperatures during an induction type smelter (IHS) without causing unwanted side reactions or contamination from other materials that may come into contact with it. By continuously recirculating the liquid aluminium through this special chamber while maintaining its stability, the technical effect of these techniques results in more efficient use of electricity, lower costs associated with production processes, higher productivity rates, reduction of harmful gases released by combustion products produced when producing new metals, increased flexibility in design options, enhanced safety features, smaller equipment size, etc., resulting in greater savings on environmental impact caused due to greenhouse gas emission regulations.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the efficiency and productivity of producing metallurgical products such as steel without requiring costly processes like reheating. Current methods have limitations including poor thermal conductance due to small areas called hearth pools, difficulty controlling the process temperatures during startup/shutdown cycles, limited space utilization, excessive energy usage, and reduced lifespan caused by increased wear on components overtime.
