specific Embodiment approach 1

[0012] Specific embodiment one: In this embodiment, a kind of online pre-coating process of wire drawing is completed according to the following steps:

[0013] In the wire drawing preparation process, the on-line coating process is used to replace the tank-type soaking process or the on-line coating process before drawing, and the steel wire after cold drawing is annealed to obtain the annealed steel wire, and then the annealed steel wire is transferred to the multi-tube type Coating is carried out in the online coating machine continuously, the wire is blown after coating, the wire is dried after blowing, and the wire is taken up after drying, and the online pre-coating of wire drawing is completed.

[0014] The beneficial effect of this implementation mode:

[0015] 1. This embodiment is an on-line pre-coating process for wire drawing. The online coating production process after continuous annealing of steel wire replaces groove coating or online coating before wire drawing...

specific Embodiment approach 2

[0017] Embodiment 2: This embodiment differs from Embodiment 1 in that: the steel wire is stainless steel wire or nickel-based alloy steel wire, and the wire diameter of the steel wire is 1.4mm-4.0mm.

[0018] Other steps are the same as in the first embodiment.

specific Embodiment approach 3

[0019] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the annealing is to anneal the cold-drawn steel wire in a multi-tube protective atmosphere continuous annealing furnace.

[0020] Other steps are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to a wire drawing online precoating process, relates to the technical field of wire drawing production, and aims to solve the problems that an existing groove type soaking coating process is high in energy consumption, low in coating uniformity, and relatively high in production cost, the wire drawing efficiency of an existing before-drawing online coating process is restricted by online coating, and the working efficiency is low. A method comprises the following steps of replacing a groove type soaking process or a before-drawing online coating process with an online coating process during the wire drawing preparation process, annealing a cold-drawn steel wire to obtain an annealed steel wire, then transferring the annealed steel wire into a multi-tube type continuous online coating machine for coating, performing wire blowing after coating, drying after wire blowing, and taking up after drying, thereby completing the wire drawing online precoating. The wire drawing online precoating process can be obtained.

Description

technical field [0001] The invention relates to the technical field of drawing production. Background technique [0002] In order to ensure the quality of wire drawing in the cold drawing process, pre-coating is generally required. Stainless steel and nickel-based alloys generally require annealing treatment after repeated drawing due to their high work-hardening tendency. The general domestic annealing process generally adopts multi-tube high-temperature online protective atmosphere annealing. After annealing, pre-coating is generally carried out before wire drawing. There are roughly two types of process methods: one is the process of soaking in a tank and drying in a drying oven; the other is One is to install an online coating drying device in front of the wire drawing machine for online coating. However, there are certain disadvantages in these two types of processes: [0003] 1. Trough soaking coating: (a) There are many processes, high energy consumption for coating...
