Method of melting aluminum ingot in process of preparation of electrician round aluminum rod

Abstract

The invention provides a method of melting an aluminum ingot in the process of preparation of an electrician round aluminum rod. The method of melting the aluminum ingot in the process of the preparation of the electrician round aluminum rod includes the following steps: A, filling the aluminum ingot in a shaft furnace, wherein the shaft furnace is communicated with a melting chamber, the aluminum ingot is heated in a smoke waste heat environment in the shaft furnace, and the temperature of smoke of an inlet of the shaft furnace is 800-1000DEG C; B, enabling aluminum liquid melted in the melting chamber to be stored at the bottom of the melting chamber and the bottom of a heating chamber through a channel between the melting chamber and the heating chamber, and soaking the aluminum ingot moving downward from the shaft furnace into the aluminum liquid at the bottom of the melting chamber; C, starting a main burner of the heating chamber, wherein the main burner heats the aluminum liquid in the heating chamber; and D, enabling high-temperature smoke of the heating chamber to enter the melting chamber through the channel between the melting chamber and the heating chamber, heating the aluminum liquid in the melting chamber and melting the ingot through the high-temperature smoke, and preheating the aluminum ingot filled in the shaft furnace after the high-temperature smoke enters the shaft furnace. The method of melting the aluminum ingot in the process of the preparation of the electrician round aluminum rod not only utilizes the smoke waste heat to melt and preheat the aluminum ingot and improves the heat efficiency but also achieves soaking type melting and reduces burnt loss.

Description

technical field [0001] The invention relates to the field of preparation methods for electrical aluminum rods, in particular to a method for melting aluminum ingots during the preparation of electrical round aluminum rods. Background technique [0002] In the electrical round aluminum rod industry, the single-hearth cupola (shaft furnace) is used to smelt aluminum raw materials. The melting of aluminum ingots is directly raised by the heat generated by burning the surface of aluminum ingots set in the furnace. The temperature of the ingot, when the temperature of the aluminum ingot rises to the melting point of aluminum, it is melted into molten aluminum, and the molten aluminum is continuously poured into the holding furnace through the water outlet of the cupola. [0003] The problems posed by single-hearth cupolas are as follows: [0004] 1. The temperature of the molten aluminum is low: the aluminum ingot and the molten aluminum are in the same furnace, and most of the ...
