Embodiment 1
[0035] The manufacture method of high anticorrosion fishery steel wire rope of the present invention comprises the following steps:
[0036] 1. Select high-carbon steel wire rods, use hydrochloric acid to pickle the wire rods, wash away impurities such as floating rust and scale on the surface of the wire rods, and prepare for phosphating, and put the pickled wire rods into the phosphating pool For 5 minutes, the pyrophosphate solution at about 94°C in the phosphating pool will coat the surface of the wire rod with a dense phosphating film. The phosphating film has two functions, one is its own lubrication, and the other is its own lubrication. The special structure can bring lubricating powder into the wire drawing machine to enhance lubrication;
[0037] 2. Use a straight-in wire drawing machine to draw the wire rod in separate passes, and then heat it to about 908°C for lead quenching. The quenching temperature is about 549°C, and then use a straight-in wire drawing machine...
Embodiment 2
[0054] The manufacture method of high anticorrosion fishery steel wire rope of the present invention comprises the following steps:
[0055] 1. Choose medium-carbon steel wire rod, pickle the wire rod with hydrochloric acid, put the pickled wire rod into the phosphating pool for 3 minutes, and the phosphating pool is a pyrophosphate solution at about 87°C, so that the wire rod The surface is coated with a dense phosphating film;
[0056] 2. The wire rod is drawn in separate passes by a straight wire drawing machine, and then heated to about 892°C for lead quenching. The quenching temperature is about 542°C, and the quenched semi-finished steel wire is again used by a straight wire drawing machine. Pulling in separate lanes,
[0057] 3. Carry out galvanizing operation on the steel wire obtained in step 2, and the running speed is 28m / min. The specific steps are:
[0058] (1) Put the full steel wire I-shaped wheel on the pay-off bracket, and the steel wire first enters the ope...

[0073] The manufacture method of high anticorrosion fishery steel wire rope of the present invention comprises the following steps:
[0074] 1. Select high-carbon steel wire rods, pickle the wire rods with hydrochloric acid, put the pickled wire rods into the phosphating pool for 5 minutes, and the phosphating pool is a pyrophosphate solution at about 90°C, so that the wire rods The surface is coated with a dense phosphating film;
[0075] 2. The wire rod is drawn in separate passes by a straight-in wire drawing machine, and then heated to about 900°C for lead quenching. The quenching temperature is about 545°C. Pulling in separate lanes,
[0076] 3. Carry out galvanizing operation to the steel wire obtained in step 2, and the running speed is 25m / min. The specific steps are:
[0077] (1) Put the full steel wire I-shaped wheel on the pay-off bracket, and the steel wire enters the open flame furnace first, and the open flame furnace is filled with lead liquid at a temperature...
