Abstract
The invention discloses a drawing rust removal process for steel wires, which comprises the following steps: firstly, carrying out acid cleaning on a wire after heat treatment; secondly, cleaning the wire rod after the acid cleaning by using high pressure; thirdly, rinsing in a rinsing bath; fourthly, after cleaning, exposing the substrate in air to increase oxidation; fifthly, the mixture enters a hydrochloric acid tank again for secondary acid washing; and sixthly, carrying out the next process after secondary acid washing. The drawing rust removal process for the steel wire rod can be used for removing the surface carbon deposition after heat treatment of various medium and low carbon steel and chromium-molybdenum alloy steel materials, the surface quality of the formed wire rod can be effectively improved by treating the surface of the wire rod in the production process, other processes are not needed to be added, and the cost is saved.
Description
Technical Field
The invention relates to a drawing rust removal process for a steel wire.
Technical Field
Need carry out drawing of wire rod in the production process of steel type wire rod, commonly known as stretch the line, in order to stretch the smooth and easy going on of line technology, need scribble at the wire rod outer and stretch line powder (the principal ingredients is calcium stearate), and will stretch line powder partially on the wire rod surface when stretching the line and accomplishing, reentrant thermal treatment can form surperficial long-pending charcoal because of high temperature sintering, and later stage pickling is difficult thoroughly clean up, not only influences the wire rod quality, still can increase the processing cost, influences the performance of enterprises.
Disclosure of Invention
The invention aims to provide a drawing rust removal process for a steel wire, which can realize direct forming of the wire after drawing by improving the process in the acid washing process and adding the rust removal process, does not need redundant process for operation, reduces the production cost and improves the production quality.
In order to solve the problems, the drawing rust removal process for the steel wire rod adopts the following technical scheme:
a drawing rust removal process for steel wires comprises the following production processes:
firstly, carrying out acid cleaning on a wire after heat treatment;
secondly, cleaning the wire rod after the acid cleaning by using high pressure;
thirdly, rinsing in a rinsing bath;
fourthly, after cleaning, exposing the substrate in air to increase oxidation;
fifthly, the mixture enters a hydrochloric acid tank again for secondary acid washing;
and sixthly, carrying out the next process after secondary acid washing.
Further, in the first step, the pickling time is 15 to 30 minutes.
Further, in the third step, the pH value of the rinsing bath is set to 1-2, and the rinsing time is not more than 1 minute.
Further, in the fourth step, the exposure time is 4 to 8 hours.
Furthermore, in the fifth step, the secondary acid washing adopts a rapid acid washing mode, and the time is 1-3 minutes.
Further, under the secondary pickling of the fifth step, pickling can be repeated once when the product fails to reach the surface quality, and the repeated pickling is not more than twice on the premise of meeting the quality requirement.
The invention has the beneficial effects that: the drawing rust removal process for the steel wire rod can be used for removing the surface carbon deposition after heat treatment of various medium and low carbon steel and chromium-molybdenum alloy steel materials, the surface quality of the formed wire rod can be effectively improved by treating the surface of the wire rod in the production process, other processes are not needed to be added, and the cost is saved.
