Marine rope manufacturer analysis what are the purpose of the galvanized steel wire rope?

Galvanized steel wire rope & have spent Can be used in the advanced areas such as construction, transport, binding, traction, strapping, used for shipping, offshore oil exploration, aircraft and Marine fishing, fishing.     Galvanized steel wire rope of the commonly used sisal rope ever and jute, but because of these materials on the job easy adsorption of acid, alkali, water and other corrosive, caused the inner wire early corrosion broken wires, use polypropylene rope.     Of galvanized steel wire rope twist and common circular strands wire rope is the same, but according to working conditions, steel wire rope used for steel wire of the zinc layer thickness of material have different requirements: diameter of 0. 2 ~ 5. 0 mm long and I number of galvanized steel wire rope, coated galvanized steel wire rope can be divided into 3 groups: the thickness of thin coating group on the zinc content of 15 ~ 135 g/m2, for mild corrosive conditions; On zinc coating group in the amount of 60 ~ 200 g/m2, used for medium corrosion conditions; Thick galvanized zinc group of 75 ~ 260 g/m2, used in severe corrosion conditions. In order to ensure the quality of the steel wire rope, steel wire galvanized layer surface should be smooth and complete, uniform and firm. When spiraling galvanized steel wire winding 5 or 10 times the diameter of steel wire diameter mandrel, zinc layer should not fall off or crack. Corrosion resistant ability of the galvanized layer, also should make a corresponding test.     How line continuous hot dip galvanizing of steel wire and two ways of plating.     Electric galvanized ( See wire electric galvanized) Is through additional power supply, power deposition way coating, the coating is obtained by the fine grain of pure zinc. Hot dip galvanized, See the steel wire galvanizing) Is to rely on the physical 'formed by the thermal diffusion coating, iron a zinc compounds, forming first, one after another in a zinc compound generated on the surface of pure iron zinc layer. In theory, can obtain arbitrary thickness of galvanized zinc layer. Practical on galvanized zinc volume up to 1200 g/m2. , general electric galvanized zinc layer quantity is up to 750 g/m2. And hot dip galvanized zinc peak also however 593 g/m2. Galvanized, can reduce the mechanical properties of steel wire for high strength and high corrosion resistance of galvanized steel wire rope, use electric galvanized steel wire twisting system more. Drawing is galvanized steel wire rope production would undergo an operation in the process of link, and drawing on the staff need to pay attention to what kind of problem?     When we staff operation, you must try to keep inside the reel and mould box between water flow, if it is found that the wire has been cooling, but also water should stop the vehicle's operation. Under normal circumstances, the mold box of the water temperature can not exceed 50 degrees Celsius, and the inside of the tank lubricants also need to keep circulation state, the temperature of the lubricant can not exceed seventy-five degrees Celsius, needs a check every shift.     When we are drawing attention should be paid to should be strictly comply with the operating sequence. Not able to jump to operate. For wire rope on the diameter of the wire should be carefully check, can be retained within a permitted deviation. But if it has more than the diameter of the rules within the scope of the error, and should be replaced in time, will not be able to continue into the next action line.
