Abstract

Disclosed is a cyclic cooling device for twisting thick galvanized steel wire rope strands. A pressing cover is arranged on a tile body and tightly connected with the tile body through M4*10 hexagon socket head cap screws, the tile body is internally provided with a groove hole, and the side edge of the tile body is provided with an oil inlet and an oil outlet; the device is placed into a pressingwire tile box, cooling oil is fed from the oil inlet of the tile body and discharged from the oil outlet, the cooling oil is driven by a motor to circulate to cyclically cool the rope strands, and the softening, stripping and accumulating phenomena of zinc layers of the thick galvanized steel wire rope strands are prevented.

Description

technical field [0001] The invention relates to a circulating cooling method and device for twisting thick galvanized steel wire strands, belonging to the technical field of metal product processing equipment. Background technique [0002] The service life of thick galvanized fishing wire rope depends on the corrosion resistance of the wire rope. Ocean fishing has a certain range of cycles. If the service life of the wire rope does not reach the cycle of its going to sea, it will seriously affect the user's operation. The steel wire ropes used by marine ships are often under the alternating action of ocean atmosphere-sea water-sunlight radiation. According to measurements, the surface temperature of the water area under normal conditions is 28-29°C, the NCL is 3.5-3.6%, the conductivity is 0.39Ω / cm, and the flow rate is 4.5m / s, with an oxygen content of 5-6mg / L, which is highly corrosive to steel wire ropes. The reason for the scrapping of steel wire ropes is mainly due t...
