Abstract

The invention discloses a wire rod coiled material annealing furnace, which comprises a furnace body, a furnace cover, a wire rod and a wire rod, the flow guide device is contained in the hearth, and a first flow guide channel and a containing cavity communicated with the first flow guide channel are formed in the flow guide device; the circulating fan comprises a first air outlet connected with the first flow guide channel and an air return opening connected with the containing cavity. The heating device is accommodated in the first flow guide channel; wherein the containing cavity is internally provided with a material disc for bearing the coiled material, the material disc comprises a guide sleeve, the coiled material is concentrically arranged on the periphery of the guide sleeve in a sleeving mode, an inner ring airflow channel is formed between the inner ring of the coiled material and the guide sleeve, an outer ring airflow channel is formed between the outer ring of the coiled material and the fluid director, and the outer ring airflow channel is communicated with the inner ring airflow channel. The air flow flowing into the containing cavity flows back to the air return opening along the outer ring air flow channel and the inner ring air flow channel at the same time. The coiled material heating device can realize rapid and uniform heating of coiled materials.

Description

technical field [0001] The invention relates to an annealing furnace, in particular to an annealing furnace for wire rod coils. Background technique [0002] During the processing of wire rod coils such as aluminum rods, recrystallization annealing is required, and during the recrystallization annealing wire rod process, the temperature needs to be raised rapidly in the annealing furnace, and at the same time, the heating uniformity of the wire rod needs to be ensured. Therefore, the annealing furnace The power, heating speed and uniformity requirements are very high. However, the existing annealing furnace has a slow heating speed and uneven heating of the wire rod, thus resulting in a very low yield rate of the wire rod. [0003] Therefore, it is necessary to improve the prior art to overcome the defects in the prior art. Contents of the invention [0004] The object of the present invention is to provide an annealing furnace for wire rod coils to realize rapid and uni...
