Novel heated-air circulation tempering furnace

Abstract

The invention relates to a novel heated-air circulation tempering furnace, and belongs to a medium-and-low temperature soft thermal treatment device for metal. The novel heated-air circulation tempering furnace comprises a feeding table, a furnace body and a discharging table, wherein the furnace body comprises an outer furnace shell, a furnace body heat preservation layer, an inner liner, and a blower and heating elements which are arranged on the furnace body; the blower is provided with an air suction inlet and an air outlet; a hot flow guide system is arranged below the air outlet; carrier rollers are arranged below the hot flow guide system; a first roller, a second roller and a third roller are arranged inside the feeding table; a fourth roller, a fifth roller, an out-furnace cold air blowing system and a speed reducer are arranged in the discharging table; and the furnace body is of a modular structure. The heated-air circulation tempering furnace has a unique structure of a heated-air circulation channel and is convenient for circulating heated air more uniformly so as to ensure the higher uniformity of the furnace temperature; the modular structure is adopted and each area is a module; and according to process characteristics of processed products, the modules can be added or reduced randomly so as to change the length of the furnace body to adapt to different thermal treatment processes.

Description

Technical field: [0001] The invention relates to a novel hot air circulation tempering furnace, which belongs to a medium-low temperature gentle heat treatment device for metals. Background technique: [0002] Most of the hot air in the medium and low temperature hot air circulation tempering furnaces in the prior art adopts horizontal circulation, and the hot air in each heating zone will affect each other; the heating devices are scattered, which is not convenient for installation and maintenance. The hot air circulation tempering furnace in the prior art The body is mostly monolithic, and its length and other structures cannot be changed according to the process requirements of different products. Invention content: [0003] In order to solve the above technical problems, the present invention provides a new type of hot air circulation tempering furnace that can be used for tempering, solid solution or aging treatment requiring high furnace temperature uniformity.
