Aluminum profile smelting furnace

Abstract

The invention discloses an aluminum profile smelting furnace. The aluminum profile smelting furnace comprises a box body and a furnace body; the furnace body is arranged in an inner cavity of the box body; a heating resistance wire is in winding connection to a vertical surface on the outer surface wall of the furnace body; a fixed plate is welded at the bottom of the heating resistance wire; a rotating plate is arranged at the bottom of the fixed plate, and is movably connected with the fixed plate through an engagement convex block; a cover cap is sleeved at the top of the furnace body; a connecting hoop is sleeved at the external of the cover cap; and the connecting hoop and the cover cap are rotationally connected through a connecting base. In the aluminum profile smelting furnace, the heating resistance wire is heated through commercial power, and a magnetic field is formed on the inner side of the heating resistance wire, so that the quick heating of aluminum profiles is realized; and compared with a traditional flame heating mode, the electromagnetic heating mode is high in energy utilization rate and heating speed, reduces the machining cost, and meanwhile, improves the heating efficiency.

Description

technical field [0001] The invention belongs to the technical field of aluminum profile processing equipment, in particular to an aluminum profile smelting furnace. Background technique [0002] A smelting furnace refers to a furnace for melting iron ore, such as melting hematite (Fe 2 o 3 ) or magnetite (Fe 3 o 4 ), turning it into pig iron. This kind of furnace body is a tall columnar structure lined with refractory materials. It is filled with selected ore, coke and solvent (the solvent is usually limestone) from the top. The transformation of iron oxide into metallic iron is a reduction process, and carbon monoxide and hydrogen are used in the process. reducing agent.

Problems solved by technology

[0003] Aluminum profiles need to use smelting furnaces in the process of processing. However, the existing smelting furnaces still have deficiencies in the process of use. First, the existing smelting furnaces are often heated by flame heating. However, in the process of flame heating There are often problems of energy loss and slow heating speed, which lead to a slow heating process of aluminum profiles; secondly, the existing smelting furnaces often keep the furnace body fixed during the process of heating aluminum profiles, so that the aluminum profile The heat in the heating process is often difficult to be evenly heated, thereby reducing the heating efficiency of the aluminum profile; secondly, the caps on the top of the existing smelting furnaces are often connected by a screw-in connection, so that the removal and installation of the caps are very difficult. will proceed more slowly
