Stainless steel wire annealing device and annealing method thereof

Abstract

The invention discloses a stainless steel wire annealing device and an annealing method thereof. The stainless steel wire annealing device comprises a base, an installation plate C is arranged on one side of the top of the base, a wire guide cylinder is arranged on the other side of the top of the installation plate C, an installation plate B is arranged on the other side of the top of the installation plate C, and conveying wheels are rotationally connected to the tops and the bottoms of the two ends in the installation plate B through fixed shafts. Through cooperation of sleeves, hinge rods, a lifting plate, a contact piece A, a contact piece B, a connecting rod A and a heat conducting plate, after the temperature in a heating pipe is too high, the heat conducting plate conducts heat in an installation pipe A into an installation bin, gas in the installation bin is heated to expand, the gas pressure is increased, and through cooperation of connecting rods B, pistons and springs A, the lifting plate is driven to move downwards. The contact piece A is separated from the contact piece B, and therefore a circuit of the heating pipe is turned off, the annealing temperature is controlled, the temperature floats up and down in the most appropriate state, and the annealing quality of stainless steel wires is ensured.

Description

technical field [0001] The invention relates to the technical field of heat treatment of stainless steel wires, in particular to an annealing device for stainless steel wires and an annealing method thereof. Background technique [0002] Annealing is a metal heat treatment process. It refers to slowly heating the metal to a certain temperature, keeping it for a sufficient time, and then cooling it at an appropriate speed. The purpose is to reduce hardness and improve machinability; reduce residual stress, stabilize size, and reduce deformation and cracks. Tendency: refine the grain, adjust the structure, and eliminate the defects of the structure. To be precise, annealing is a heat treatment process for materials, including metal materials and non-metal materials, and the annealing purpose of new materials is similar to that of traditional metal annealing. [0003] The annealing effect of stainless steel wire is affected by the return temperature. If the annealing temperatur...

Problems solved by technology

[0004] The purpose of the present invention is to provide a stainless steel wire annealing device and annealing method thereof, to solve the above-mentioned background technology that the effect of stainless steel wire annealing is affected by the retraction temperature, if the annealing temperature is too high, the hardness of the stainless steel wire will become high, making The wire is not easy to bend. If the annealing temperature is too high, the hardness of the stainless steel wire will become lower, making the stainless steel wire easy to break during use. However, some existing stainless steel wire annealing devices cannot control the annealing temperature well when they are in use. As a result, the quality of the produced wire rods is uneven; the annealing temperature of stainless steel is high, and it is easy to oxidize and change color. Generally, a reducing protective gas is used to reduce it. The gas used is generally ammonia gas, and the ventilation method is to use The pump injects ammonia gas into the interior of the equipment. Since the wire moves very slowly during the transmission process, continuous injection of ammonia gas will cause a large amount of ammonia gas to accumulate in the reaction chamber and be wasted; when the equipment is not in use, some Residual ammonia gas will be emitted from the reaction chamber to the outside. Since ammonia gas has a certain pungent smell, the outflowing ammonia gas will cause related problems related to the pollution of the external environment.
