Background
The aluminum-clad steel wire drawing process is a cold pressure processing process, aluminum-clad steel buses are drawn and accumulated through a winding drum by a circular aperture die with a smaller diameter, the buses pass through the die to be extruded and deformed, the diameter is reduced, and simultaneously, the strength is increased due to the work hardening effect. And drawing the aluminum-clad steel bus with a certain diameter for multiple times to form the aluminum-clad steel wire with the required diameter and strength. In the drawing process, in order to reduce the heat generated by friction between an aluminum layer and a die alloy material when a bus passes through a die, a good lubricant is needed for lubrication, meanwhile, the aluminum-clad steel wire is extruded and deformed, the deformation resistance of a steel core and the aluminum layer generates a large amount of heat, the friction heat and the deformation heat cause the temperature of the aluminum-clad steel wire to rise, the temperature of the aluminum-clad steel wire in the die can reach more than 300 ℃ instantly, the temperature rise can cause the steel core to form low-temperature tempering, the irreversible brittleness is generated, the steel core cannot be drawn or processed continuously, and the wire breakage phenomenon is generated.
The prior art adopts cooling methods such as water-cooling, forced air cooling to cooperate and realizes the reel cooling, as the application document of patent number CN108746233B discloses water tank wire drawing machine group, including the frame, still include the cooling bath, establish the first cooling body in the frame of cooling bath top and drive first cooling body pivoted actuating mechanism, first cooling body is including rotating the live-rollers that connects the frame and can supply the aluminium package steel wire to pass, by actuating mechanism drive and can drive live-rollers pivoted axis of rotation, equipartition at a plurality of cooling parts of live-rollers circumference and can extrude the extrusion piece that the cooling part carries out the water spray to the aluminium package steel wire. Realized automatic water spray that absorbs water carries out the water-cooling to aluminium package steel wire, along with the continuous walking of aluminium package steel wire and the continuous rotation of live-rollers, can be continuous cool down the operation, cold water direct action is on aluminium package steel wire, and it is effectual to cool down, has avoided the problem that aluminium package steel wire cooling is not up to standard takes place brittle failure.
But along with equipment constantly moves, reel inner wall steel soaks in water, can produce the corrosion, corrodes the reel, and the finish coat seriously reduces the heat conductivity, and prior art adopts the mode rust-resistant of reel inner wall painting or zinc-plating, still has following problem: a large amount of cooling water is sprayed on the wall of the high-temperature winding drum, scale is continuously precipitated, the main components of the scale are calcium carbonate, magnesium hydroxide and the like, and the scale is continuously thickened to seriously hinder heat conduction.
