Problems solved by technology

However, in general annealing furnaces, since the heating zone directly enters the cooling zone, the annealing treatment of workpieces often reduces the qualified rate of workpieces due to rapid cooling, and the existing preheating and cooling zones are relatively short, which is not suitable for annealing of large workpieces.

Abstract

The invention provides an oversize heat recovery-type push disc-type wire continuously and isothermally-balling annealing furnace, comprising a furnace body, wherein a front gate for feeding work pieces is arranged on a front end of the furnace body; a back gate for discharging work pieces is arranged on a tail end of the furnace body; a pre-heating area, a heating area and a cooling area are orderly arranged in the furnace body; an isothermal area further is arranged between the heating area and the cooling area; a roller guide rail for realizing technical movement of work pieces is arranged in the furnace body; a feeding table is arranged on an inlet end of the front gate; a discharging table is arranged on an outlet end of the back gate; and a cycle heat recovery system for increasing heat efficiency of the annealing furnace. The annealing furnace can realize annealing for work pieces in batch, especially, the annealing furnace can be applied to continuously annealing and processing wires, and therefore, the efficiency is higher.

Description

technical field [0001] The invention relates to a spheroidizing annealing furnace, in particular to an extra-large heat recovery type push plate type continuous isothermal spheroidizing annealing furnace for wire rods. Background technique [0002] In the prior art, an isothermal spheroidizing annealing furnace is used for normalizing and annealing the metal workpiece. However, in general annealing furnaces, since the heating zone directly enters the cooling zone, the annealing treatment of the workpiece often reduces the pass rate of the workpiece due to rapid cooling, and the existing preheating and cooling zones are relatively short, which is not suitable for annealing of large workpieces. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned technical problems, and provide a super-large heat recovery type push-disk type continuous isothermal spheroidizing annealing furnace for wire rods. [0004] The purpose of the pre...
