Infrared gas jet flow aluminum rod heating furnace

Abstract

The invention relates to an infrared gas jet flow aluminum rod heating furnace, which includes a furnace body, a fan, a gas combustion gun and an aluminum rod conveying mechanism, and an independent combustion chamber is arranged in the furnace body, and the combustion chamber communicates with the gas combustion gun to burn There are several groups of compression nozzles in the lower part of the chamber, and each aluminum rod to be heated is arranged directly below a group of compression nozzles; the fan adopts an axial flow compression fan, and the shaft and blades of the axial flow compression fan are inserted into the combustion chamber , its position is on the upper part of the combustion chamber, and its blades are on the upper part of the gas combustion gun and directly above the compression nozzle. This design makes the hot air act on the aluminum rod at high speed, the heating speed is fast, and the time required is short, which improves the production. Efficiency, circulating air duct and infrared radiant panels make the heat concentrated and radiated with less loss, which can save 30-50% of gas, high energy utilization rate, and greatly reduce production costs.

Description

technical field [0001] The invention relates to matching heating equipment used for processing and forming aluminum materials, in particular to a gas heating furnace for heating aluminum rods as raw materials. Background technique [0002] In the production and processing of aluminum profiles, the aluminum rod heating furnace is a necessary supporting equipment. At present, most of the aluminum rod heating furnaces adopt the heating method of simple hot air circulation, that is, a centrifugal fan is installed outside the furnace, and the fan sends hot air into the heating furnace, and the air in the furnace is drawn out to reheat and circulate the air. The characteristic of its technology is: the heating furnace is first heated by hot air, the aluminum rod absorbs heat statically in the furnace, and finally the aluminum rod or metal rod in the furnace is heated to a predetermined temperature. This is the most conventional and commonly used technology. Its disadvantages are:...

AI Technical Summary

Problems solved by technology

This is the most conventional and commonly used technology. Its disadvantages are: the aluminum rod only relies on circulating air to absorb heat in the heating furnace, and the heating of the aluminum rod takes a long time, high energy consumption, and low energy utilization rate.

Especially at present, the use of clean energy is advocated, and heating furnaces generally use gas or natural gas. This kind of heating furnace that only relies on circulating air to absorb heat consumes a lot of gas, resulting in high production and processing costs.
