Embodiment Construction

[0019] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] Example figure 1 As shown, the present embodiment provides a hydrogen annealing furnace for a bright heat treatment production line, including a furnace body, nine channel pipes, nine air pipes, resistance wires, gas sources and power supplies; the furnace body is strip-shaped, and the length is eight meters. Or other lengths can be selected according to annealing requirements. The outer wall of the furnace body is provided with an insulating layer. The gas source is a mixed gas of three parts hydrogen and one part nitrogen, or a gas without oxygen. The pressure of the gas source is greater than normal pressure. The channel tube is made of oxygen-free seamless stainless steel tube. Nine channel tubes run through the furnace body in parallel. One end of each gas tube is connected to the radial conduction of the corresponding channel tub...

Abstract

The invention provides a hydrogen annealing furnace for a bright heat treatment production line, which includes a furnace body, a channel pipe, a gas pipe, a resistance wire, a gas source and a power supply. The gas source is connected, the resistance wire is installed in the furnace body and connected to the power supply, and the resistance wire is respectively insulated from the furnace body and the channel pipe; the equipment cost is low, the structure is simple, the annealing efficiency is high, and the process requirements for oxygen barrier annealing are met.

Description

technical field [0001] The invention relates to a hydrogen annealing furnace, in particular to a hydrogen annealing furnace for a bright heat treatment production line. Background technique [0002] In the annealing heat treatment process of the steel wire rope, a heating equipment is needed, which can heat the steel wire rope and maintain a relatively appropriate temperature for a period of time. At present, the annealing equipment on the market has high cost, complex structure, and can not be well In the case of oxygen isolation, the steel wire rope is annealed to treat the defects. Contents of the invention [0003] The purpose of the present invention is to provide a simple and low-cost annealing equipment to solve the problem of high-efficiency annealing of steel wire ropes in the absence of oxygen. [0004] In order to achieve the above object, the present invention provides a hydrogen annealing furnace for a bright heat treatment production line, which includes a f...
