What kind of wire rope should be used in high temperature environment?

Select the wire rope according to the service conditions. In a high temperature environment, such as lifting a casting crane, the ambient temperature of the steel wire rope may reach 100 degrees Celsius, and the grease and fiber core will burn at high temperature, resulting in the direct failure of the steel wire rope. The operating temperature is 70- 100℃. It is recommended to use wire rope without grease. If the temperature is higher, the metallographic structure of the wire rope will change directly, and the mechanical properties of the wire rope will drop sharply, which is very prone to accidents. \x0d\ Select the main variety of wire rope according to the actual working conditions: \x0d\ 1. Phosphating coated steel wire rope (China invention patent) is an upgraded product of smooth steel wire rope after manganese or zinc-manganese phosphating treatment, which comprehensively improves the wear resistance and corrosion resistance of steel wire surface. Oil permeates into the pores of phosphating film, which has excellent antifriction effect and effectively inhibits fretting wear. The service life in atmospheric environment is much longer than that of smooth steel wire rope with the same structure, including imported steel wire rope (at present, the fatigue life of phosphating rope is about 2-3 times that of smooth steel wire rope, which can be compared by fatigue test. In the future, with the in-depth study of wear-resistant phosphating solution, the service life may be greatly improved. Phosphating film 3-60g/m2. The steel wire is directly twisted without drawing after phosphating. Note: Zinc phosphating for wire drawing should not be confused with manganese phosphating for rope steel wire). This technology is suitable for producing all kinds of wire ropes, such as elevator wire ropes, important wire ropes, mine wire ropes, anti-rotation wire ropes, wire ropes for oil production, wire ropes for pile drivers, etc. (Baidu Library has phosphate coated steel wire rope for free download). \x0d\2。 Galvanized steel wire rope includes hot dip galvanizing and electro-galvanizing. The thicker the zinc layer, the stronger the corrosion resistance, and the longer the service time, the thinner the electro-galvanizing. Hot dip galvanized steel wire rope should be used in water. Because phosphating film has certain corrosion resistance, manganese phosphating film steel wire rope can be used instead of some kinds of thin galvanized steel wire rope, such as high temperature environment with atmospheric environment but humid air. \x0d\3。 Stainless steel wire rope, such as 304 or 3 16 stainless steel wire rope, has higher corrosion resistance than hot-dip galvanized carbon steel wire rope and is relatively expensive. The service life of stainless steel wire can also be greatly prolonged by manganese phosphating coating (phosphating of stainless steel wire requires special phosphating formula). \x0d\4。 Plastic coated steel wire rope: on the basis of carbon or galvanized steel wire rope, polyethylene and polypropylene are coated on the outer layer of steel wire rope or strand rope. \x0d\5。 Smooth steel wire rope was put into production in Britain 1834, and Tianjin No.1 Wire Rope Factory was put into production in China 1939 (bankruptcy in 2005). With a large number of phosphating coated wire ropes entering the market, they will be completely eliminated by phosphating coated wire ropes.
