Abstract

The invention discloses a heat treatment furnace for steel wire heat treatment, and relates to the technical field of steel wire production. The heat treatment furnace comprises a furnace body shell,a steel wire inlet and a steel wire outlet, a ceramic fiber plate is adopted as the lining for the structure of the furnace body, a light brick is laid on the ceramic limiting plate, the material price of the heat treatment furnace is low, so that the price of the finally built heat treatment furnace can be effectively reduced; in terms of energy consumption, the power distribution cabinet controls on-off and heating temperature of a plurality of sets of heating resistance wires, so that the energy consumption of the heating resistance wire can be effectively controlled; and furthermore, the structure of a heating cavity of the heat treatment furnace can be effectively controlled, the heat preservation and the heat insulation of the heating cavity can be effectively realized under the limitation of the light brick and a heat insulation material, the heat in the heating cavity can be well controlled, and the problem that the energy consumption is increased due to the fact that heat is leaked is avoided.

Description

technical field [0001] The invention relates to the technical field of steel wire heat treatment, in particular to a heat treatment furnace for steel wire heat treatment. Background technique [0002] Heat treatment is a very important process in the production process of steel wire. After heat treatment, the steel wire will regain the conditions that are conducive to cold drawing. Simply put, after the wire rod or steel wire is cold-drawn, the molecular structure changes. Although the strength increases, it is more brittle and breaks. When it reaches a certain level, it cannot be drawn smoothly and will be broken. [0003] The structure inside the steel wire is restored again by heat treatment. In order to facilitate re-drawing, it is not easy to break, and can achieve the required strength. The purpose of steel wire heat treatment: (1) Eliminate the work hardening of the steel wire in the previous cold drawing process, so as to facilitate the continued cold drawing. (2)...
