1 phosphating coated steel wire rope (patented product), the steel wire is phosphatized by manganese series or zinc-manganese series, and the surface of the steel wire is very wear-resistant, effectively inhibiting the occurrence of fretting wear. It is an upgraded product of smooth steel wire rope, and its service life far exceeds that of smooth steel wire rope with the same structure, including steel wire rope imported from developed countries such as Germany and Japan. At present, foreign countries have innovated our country's cottage wire rope technology. This innovative technology is suitable for almost all kinds of carbon steel wire ropes, such as elevator wire ropes and important wire ropes.
2. Galvanized steel wire rope, including hot dip galvanizing and electro-galvanizing. The thicker the zinc layer, the longer the service time and the thinner the zinc electroplating. The thicker the zinc layer, the stronger the corrosion resistance. Because the phosphating film has certain corrosion resistance, manganese phosphating film steel wire rope can replace some varieties of thin galvanized steel wire rope, such as Grade B galvanized steel wire rope in GB89 18-2006.
3. Stainless steel wire rope, steel wire rope twisted with stainless steel wire, such as 304 or 3 16 stainless steel, is more expensive. Manganese phosphating film can also greatly prolong the service life of stainless steel wire (phosphating of stainless steel wire requires special phosphating formula).
4. Plastic coated steel wire rope: on the basis of carbon steel wire rope, the outer layer of steel wire rope or strand rope is coated with polyethylene or polypropylene.
5.1Smooth steel wire rope produced in England in 834, 1939 produced and used in Tianjin No.1 Steel Wire Rope Factory in China. With the phosphating coated wire rope entering the market, it will be completely replaced by phosphating coated wire rope.
Gross weight 15 ton, safety factor 6. The minimum breaking force of steel wire rope should reach more than 90 tons. GB89 18-2006 National Standard for Important Use Wire Rope 6* 19 Structure 1770MPa Strength Grade 40mm Diameter Wire Rope Fiber Core Minimum Breaking Force 935KN Steel Core 1065438.
