Problems solved by technology
[0003]At present, in the bead wire manufacturing industry, in order to eliminate the stress in the steel wire, the heat treatment process mostly uses high-temperature lead pot tempering. The lead medium used in this tempering method Volatile, causing air pollution and endangering the health of operators
At the same time, during the tempering process, the steel wire is also easy to bring the lead in the furnace into the subsequent washing process, causing pollution to it.
Due to the high cost of lead bath tempering, there has been a technology of tempering steel wires by using high-temperature molten sodium hydroxide lye instead of high-temperature lead liquid. The cost of sodium hydroxide is much lower than that of lead, but during the tempering process, hydrogen Sodium oxide is easy to adhere to the surface of the steel wire. After tempering, the sodium hydroxide solution on the steel wire will solidify on the steel wire and be taken to the subsequent washing process, which will increase the consumption of sodium hydroxide and stick to the surface of the steel wire. The attached sodium hydroxide cannot be recycled, which not only causes the waste of sodium hydroxide, but also affects the cleaning effect of the subsequent washing process, which is also one of the important reasons why this tempering process cannot be popularized and used
And adopt conventional wiping tool, along with the reduction of temperature, the lye on the steel wire surface is constantly solidified on the wiping tool, so that the wiping tool cannot be used for a long time, and the solid sodium hydroxide attached to the steel wire surface cannot be removed by ordinary wiping methods

Abstract
The invention discloses a steel wire tempering liquid wiping device. The device comprises a shell; a heat-insulation layer is provided on the inner wall of the shell, a steel wire inlet and a steel wire outlet are provided on the shell, a wiping fiber rack is installed in a wiping cavity, tempering liquid wiping fibers are installed on the wiping fiber rack and are high temperature resistant fibers, steel wires pass through the tempering liquid wiping fibers after tempering, the bottom of the wiping fiber rack is provided with a tempering liquid recovery means, and a heating device is installed in the shell. According to the invention, the steel wires enter into the steel wire tempering liquid wiping device after coming out from a high temperature tempering furnace; under the action of the heating means, temperature in the wiping cavity can guarantee that sodium hydroxide on the surface of the steel wires is always in a liquid state; after the steel wires pass through the tempering liquid wiping fibers, liquid sodium hydroxide is wiped off and flows into an tempering liquor recovery means; alkali liquor brought out from the tempering furnace by the steel wires is recovered, which enables waste of the alkali liquor to be avoided and prevents the steel wires from bringing the alkali liquor to a subsequent rinsing procedure, thereby preventing influence of the alkali liquor on cleaning of the steel wires in subsequent procedures.
Description
technical field [0001] The invention relates to a steel wire surface treatment device, in particular to a tempering liquid removal device used after the steel wire is tempered. Background technique [0002] Bead wire has high strength, good toughness, excellent fatigue performance and good linearity. It is mainly used for the edge of tires as a reinforcing skeleton material, and is usually drawn from high-carbon steel wire rod. In order to further improve the rust resistance, thermal aging resistance and the bonding force between the bead wire and the rubber, the bead wire is a bronze-plated steel wire, and the surface of the steel wire usually needs to be plated before bronze plating. The surface treatment before beading is particularly important. It is necessary to carry out stress tempering and water washing on the steel wire. The cleanliness of the surface treatment of the bead steel wire affects the quality of the coating. [0003] At present, in the bead wire manufact...
