High-priced steel wire rope does not mean high use cost.

The unit use cost of steel wire rope can be calculated by dividing the cost of buying steel wire rope by the number of days of use, that is, calculating yuan/day. Or the purchase cost of wire rope divided by the number of uses. You can also divide the cost of buying wire rope by the tonnage of the goods transported. Based on this data, we can compare which wire rope is used for more accounting. Cheap steel wire rope does not mean low use cost, and expensive steel wire rope does not mean high use cost.

It costs 3000 yuan to buy a certain length of smooth steel wire rope, which will be used for 100 days, and the daily use cost is 30 yuan. Spending 4500 yuan to buy phosphating coated steel wire rope with the same length can last for 300 days, and the daily usage fee is 15 yuan. Which is more suitable?

Phosphating coated steel wire rope produced by patented technology gives priority to manganese series or zinc-manganese series phosphating. Compared with the production process of smooth steel wire rope, only the last wear-resistant phosphating process is added, which greatly improves the wear resistance and corrosion resistance of steel wire rope. Phosphating steel wire rope is directly twisted. At present, the fatigue test data show that the fatigue life of phosphating coated steel wire rope is about 3-4 times that of smooth steel wire rope with the same structure (under comparable conditions in laboratory), and it is still possible to improve it greatly with the research of wear-resistant phosphating formula.

The service life of wire rope is proportional to the fatigue life. According to the approximate price of wire rope market, the price of manganese phosphating coated wire rope is about 1.4- 1.6 times that of smooth wire rope, and the service life is much longer than the price increase. Therefore, the daily average use cost of phosphating coated steel wire rope is only 30-45% of that of smooth steel wire rope, which is lower in use cost and higher in cost performance.

Therefore, phosphating coated wire rope has long service life and low use cost. It is inevitable to completely eliminate smooth wire rope, which is the general trend and the development trend of wire rope manufacturing technology.
