Description
Technical Field
The invention relates to the technical field of steel wire ropes, in particular to a steel wire rope with low loss and long service life and a processing technology thereof.
Background
The steel wire rope is an engineering rope formed by twisting a plurality of steel wires in different structures, plays a very important role in national economy, is small enough to be a daily life clothes airing machine, is large enough to be used in various industries such as machinery, aviation, construction, national defense and military industry and the like, such as car draft, cable car guide rails and the like, and has irreplaceability.
Among many steel wire ropes, galvanized steel wires have good corrosion resistance, and can be suitable for application environments such as open air, rainy days and the like. Meanwhile, the galvanized steel wire rope has lower cost and is often used in automobile workpieces such as automobile clutch, automobile traction and the like. However, as the back of the steel wire is plated with the zinc layer, the steel wire rope has the defects of cracking, falling, zinc accumulation and the like in the preparation process of stranding and the like, so that the mechanical property of the steel wire rope is poor, the abrasion is high in long-term pressure work, the defects of poor fatigue resistance, low abrasion resistance and the like are caused, and the service life of the steel wire rope is not long.
Therefore, the processing technology of the steel wire rope containing the galvanized layer needs to be optimized, defects generated by the galvanized layer in the preparation process are restrained, and the mechanical properties of the steel wire rope are ensured, so that the low-loss long-service-life steel wire rope for the vehicle is obtained, and the steel wire rope has important application value.
Disclosure of Invention
The invention aims to provide a low-loss long-life steel wire rope and a processing technology thereof, so as to solve the problems in the background technology.
In order to solve the technical problems, the invention provides the following technical scheme:
A processing technology of a low-loss long-life steel wire rope comprises the following steps:
Step 1: sequentially carrying out dry drawing, primary annealing and wet drawing on the wire rod to ensure that the diameter is 1.0+/-0.02 mm; secondary annealing to obtain pre-tensioned steel wires;
step 2: acid washing and galvanization are carried out on the pre-tensioned steel wire; then soaking in formamide solution, washing, and blow-drying to obtain galvanized steel wires;
Step 3: placing the galvanized steel wire in a wire drawing die, and carrying out drawing treatment for a plurality of times by matching with a wire drawing lubricant to obtain a basic steel wire;
step 4: spraying and twisting lubricating oil on the basic steel wire, and twisting; obtaining the steel wire rope.

Compared with the prior art, the invention has the following beneficial effects: in the scheme, after the pre-tensioned steel wire is galvanized, micro-etching is performed in formamide, so that the wear resistance of a zinc layer is improved; then combining two-section stretching processes with the assistance of a wire drawing lubricant, and effectively reducing the loss of a zinc layer in the stretching process on the basis of ensuring the drawing performance; finally, the abrasion resistance of the steel wire rope is effectively improved on the basis of effectively ensuring the twisting effect under the assistance of twisting lubricating oil, so that the effects of low loss and long service life of the steel wire rope are effectively improved.
Wherein, the galvanized steel wire rope is treated by formamide solution in advance, and microetching is performed on the surface of the galvanized steel wire rope to inhibit the defect of a surface zinc layer. Since zinc is generally deposited on the surface after galvanization, and the surface roughness of the zinc layer can be reduced by micro etching treatment in formamide solution, the surface can form a micro-nano structure, so that the structure and grain boundary effect of the zinc oxide layer can improve the hardness and the wear resistance of the surface, thereby reducing the wear in the stretching and twisting processes and reducing the surface fatigue and wear.
In the stretching process, two dies with different cone-in angles and cone-out angles form a two-section stretching process, and the strength and toughness of the steel wire rope are effectively improved on the basis of inhibiting deformation and damage of materials. The larger drawing angle can improve plastic deformation, reduce surface brittleness and inhibit cracks, and the smaller drawing angle can improve strength, so that in order to balance strength and brittleness, the drawing process is optimized by introducing two dies with the cone-in angle and cone-out angle of 2 degrees for drawing. Meanwhile, in the drawing process, a wire drawing lubricant containing an antiwear agent is introduced as an aid (the partial plastic flow of a material in the drawing process can be effectively reduced, surface cracks are restrained), the thermal damage is effectively reduced, and the thermal cracking is restrained, so that the core layer defect is restrained, and the low loss and long service life of a finished steel wire rope are improved.
Wherein, during twisting, twisting lubricating oil containing modified antiwear agent is used to reduce abrasion during twisting, thereby enhancing the wear resistance of the steel wire rope. The modification of the antiwear agent is based on alkene-click reaction, and sodium ricinoleate is grafted onto the antiwear agent, so that the dispersibility of the modified antiwear agent in twisted lubricating oil is effectively improved, the flow resistance is reduced, and sedimentation is inhibited; meanwhile, after modification, the oxidation resistance is improved, and the low-abrasion protection capability under the boundary lubrication matrix is increased, so that the friction coefficient in the twisting process is reduced, and the poor abrasion between steel wire base ropes is prevented.
The antiwear agent is prepared by taking graphene oxide as a base, carrying out in-situ zinc oxide loading through hydrothermal reaction to form composite powder, then using tannic acid to perform autoxidation coating on the surface of the composite powder, and grafting dialkyl dithiophosphate to improve wear resistance and inhibit aggregation. The zinc oxide particles and the graphene oxide flakes effectively generate sliding friction, effectively reduce friction, and are coated and grafted conveniently, so that the dispersibility is improved, and meanwhile, the high Wen Jianmo property is further improved.
