Abstract

The invention relates to a metal heat treatment device and discloses a fuel gas roller hearth continuous rapid aging furnace. The fuel gas roller hearth continuous rapid aging furnace comprises a furnace body and a temperature control system, wherein a plurality of heat treatment units are arranged in the furnace body, and each heat treatment unit comprises a workpiece area, a combustion system and a circulating fan; in each heat treatment unit, an independent combustion chamber is arranged above the workpiece area, the combustion system and the circulating fan are respectively arranged at the left end and the right end of the independent combustion chamber, and the independent combustion chamber is provided with a circulating air inlet and a circulating air outlet; air guide windows are arranged on the left side and the right side of each workpiece area, a plurality of air guide holes are arranged on each air guide window, and air inlet passages and air outlet passages are respectively formed between the air guide windows on the two sides and a furnace chamber; and inner cavities of the independent combustion chambers, air suction ports of the circulating fans, air outlets of the circulating fans, the circulating air inlets, the air inlet passages, the workpiece areas, the air outlet passages and the circulating air outlets sequentially form hot air circulating channels respectively. The fuel gas roller hearth continuous rapid aging furnace disclosed by the invention adopts an advection circulation way and is high in uniformity of furnace temperature, short in path and high in efficiency.

Description

technical field [0001] The invention relates to metal heat treatment equipment, in particular to a fast aging furnace for aluminum alloy materials. Background technique [0002] The gas-fired roller bottom continuous rapid aging furnace is currently a more advanced and efficient rapid aging furnace for aluminum alloy materials. It includes a furnace body and a temperature control system. The bottom of the furnace body is a roller table. There are several heat treatment units in the body, and each heat treatment unit includes a workpiece area, a combustion system and a circulation fan. [0003] However, in the heat treatment unit of the existing gas-fired roller bottom continuous rapid aging furnace, if the attached figure 1 As shown, the circulating fan 53 is located at the top of the furnace body, the combustion system 52 is located below the circulating fan 53, the workpiece area 51 is located below the combustion system 52, and the workpiece area 51 and the combustion sy...
