Nickel-chromium alloy furnace wire bending process for performing stress-relieving thermal treatment

Abstract

The invention discloses a nickel-chromium alloy furnace wire bending process for performing stress-relieving thermal treatment. The furnace wire winding displacement of a heating furnace is rectangular winding displacement formed by linearly arranging furnace wires of the linear heating furnace in the longitudinal direction. In the process, a bending device is used. The bending device comprises a bracket, wherein a front horizontal guide rail and a back horizontal guide rail are arranged respectively one after the other on the right side of the bracket; the middle of the right side of the bracket is provided with a bracket clamping device which is positioned between the front horizontal guide rail and the back horizontal guide rail; the right portion of the back horizontal guide rail is provided with a first bending device; the left portion of the back horizontal guide rail is provided with a third bending device; the right portion of the front horizontal guide rail is provided with a second bending device; the left portion of the front horizontal guide rail is provided with a fourth bending device. The bending device is used for forming four U-shaped bent portions in sequence from left to right on the furnace wire winding displacement of the heating furnace.

Description

technical field [0001] The present application relates to the manufacture of heating furnace wires, specifically a process for bending furnace wires made of nickel-chromium alloy for stress relief heat treatment. Background technique [0002] Heating furnaces are widely used in industry, such as billet heating, workpiece heat treatment, etc. In order to increase the heating uniformity of the heating furnace, the furnace wire is often in a curved form. [0003] For the bending of the heating furnace wire, stamping is often used in the prior art. This forming method can efficiently and quickly realize bending processing, has high processing precision and low cost, and is widely used in the prior art. However, this heating method is easy to produce a large amount of uneven deformation in the longitudinal direction of the heating furnace wire, resulting in a large change in the cross-sectional area of ​​the heating furnace wire in the longitudinal direction of the furnace wire...
