Problems solved by technology

The heating efficiency of the natural gas furnace is slow, the preheating time is long, and the furnace is large in size, which makes it troublesome to replace the alloy in production. It is necessary to withdraw the aluminum rod 6 in the furnace and reheat the new aluminum rod 6, which affects the production efficiency
The heating principle of the power frequency furnace is to use the electromagnetic eddy current effect to heat the aluminum rod. The heating speed of this scheme is fast, but the stability is poor. Poor performance, difficult to meet the needs of high-quality profiles

Abstract

The invention relates to the technical field of aluminum material machining, in particular to an aluminum bar heating method and device. A structure that a heating furnace pipe of an electromagnetic power frequency heating furnace is in butt joint with a furnace cavity of a gas furnace is adopted, an aluminum bar is subjected to efficient heating through the electromagnetic power frequency heatingfurnace firstly, and the set heating temperature is rapidly reached; and since the electromagnetic power frequency heating furnace utilizes an electromagnetic coil for heating the aluminum bar and the electromagnetic coil in part of areas needs to avoid a temperature measuring couple needle, various parts of the aluminum bar cannot be evenly heated. According to the scheme, through the additionalarrangement of the small gas furnace, part of aluminum bar efficiently heated through the electromagnetic power frequency heating furnace is continuously conveyed into the furnace cavity of the gas furnace, the furnace cavity is evenly heated through gas, heat preservation is achieved for the aluminum bar, the aluminum bar is subjected to even heat transfer in the heat preservation process, various parts of the aluminum bar are evenly heated, and accordingly the subsequent machining quality of the aluminum bar is effectively improved.

Description

technical field [0001] The invention relates to the technical field of aluminum material processing, in particular to a method for heating an aluminum rod and a device thereof. Background technique [0002] The raw aluminum rod is up to 6 meters long, and usually needs to be cut or sawed into short rods less than 1 meter before being sent to the next process; before the aluminum rod is sawed or cut, the aluminum rod needs to be heated, after heating It can be directly sent to the extruder for extrusion. It is also possible to directly heat the ingot less than 1 meter after cold sawing, and send it into extrusion after heating. [0003] In the prior art, in the heating process before aluminum rod extrusion, natural gas furnace or industrial frequency furnace is usually used for heating. The heating efficiency of the natural gas furnace is slow, the preheating time is long, and the furnace is large in size, which makes it troublesome to replace the alloy in production. It is...
