Acid-free pretreatment process for steel wires

Abstract

The invention relates to a steel wire batched physical rust removal device, and belongs to the technical field of steel wire surface treatment. The device comprises a vertical shelling wheel, a transverse shelling, a spiral steel wire brush and a rust removal machine; the vertical shelling wheel comprises a first rolling wheel and a second rolling wheel which are arranged vertically, the first rolling wheel is located on the upper portion of the second rolling wheel, and the highest point location of a wheel groove of the second rolling wheel is located between the highest point location and the lowest point location of the first rolling wheel; the transverse shelling wheel is horizontally arranged on the right side of the second rolling wheel, the spiral steel wire brush and the rust removal machine are sequentially arranged on the left side of the vertical shelling wheel, a steel wire passes through the wheel groove at the lowest point of the wheel groove of the second rolling wheeland then continues to drive forwards by surrounding the transverse shelling wheel; the spiral steel brush is composed of a spiral rod and a rust removal wire, and one end of the rust removal wire is fixedly arranged on the inner surface of the spiral rod. The steel wire batched rust removal device and process can achieve the pickling effect, and chemical pickling rust removal can be completely replaced.

Description

technical field [0001] The invention relates to the technical field of steel wire surface treatment, in particular to a device and process for batch derusting steel wire for tires that can completely replace pickling. Background technique [0002] Tire wire refers to the steel wire inlaid on the edge of the rubber tire, also known as bead wire or tire edge wire. The steel wire used to make tires is generally made by cold-drawing the steel wire with a hot-rolled wire rod. During the hot-rolling process of the wire rod, the steel wire reacts with oxygen to form a layer of hot-rolled scale on the surface of the steel wire. At the same time, due to the After being stored for a long time, rust oxidation film and oxidation spots will also be formed on the surface after being oxidized by water. The tire steel wire not only needs to have high tensile strength, toughness and good fatigue resistance, but also should have good bonding ability with rubber; It will have an adverse effe...

Problems solved by technology

[0004] However, the effect of physical rust removal in the above-mentioned methods does not reach the claimed purpose of completely replacing pickling and rust removal, and cannot completely remove the oxide layer on the surface of the steel wire. Proper pickling is required to remove the remaining oxide layer, and the complete removal of the oxide layer on the steel wire surface is an important sign to completely replace chemical pickling; in addition, the above-mentioned existing physical derusting devices and methods can only be used for one It is impossible to use the same set of equipment to process steel wires in batches at the same time, and the production efficiency is low
