7*19-1.2 Wire rope supplier stated that when choosing a wire rope, it should be considered according to different uses:
1. Wire rope breaking force: 7*19-1.2 wire rope supplier believes that under the condition of certain wire rope diameter and tensile strength, a wire rope with a large metal density coefficient should be selected. In general, the order of the density coefficient of the steel wire rope is that the surface contact rope is larger than the line contact rope, and the line contact rope is larger than the point contact rope.
2. Fatigue resistance: In general, the surface contact rope is better than the line contact rope, and the line contact rope is better than the point contact rope; the pre-tensioned rope is better than the non-pretensioned rope; the same direction twist is better than the alternating twist under the same structure ;Fiber core rope is better than metal core rope.
3. Wear resistance: 7*19-1.2 wire rope supplier said that the larger the contact surface between the steel wire on the surface of the steel wire rope and the pulley or reel, the smaller the contact stress, and the better the wear resistance. Therefore, the wear resistance is good or bad. The order is sealed rope, special-shaped strand rope, multi-strand rope, and round strand rope. For external wear resistance, the diameter of the outer steel wire is thicker; for internal wear resistance, line contact and surface contact are superior to point contact.
4. Agent pressure resistance: It is mainly manifested in the ability of the steel wire rope to resist structural deformation when subjected to lateral agent pressure. Generally, the metal rope core is better than the fiber rope core, the one with fewer strands is better than the one with many strands, the line contact is better than point contact, the surface contact is better than line contact, and the same structure alternate twist is better than the same direction twist.
5. Softness: The 7*19-1.2 wire rope supplier said that when the diameter of the rope is the same, the more the number of steel wires, the greater the flexibility coefficient and the better the flexibility.
6. Structural elongation and modulus of elasticity: 7*19-1.2 wire rope supplier believes that in the case of fixed-length use or rope adjustment is cumbersome or difficult, a steel wire rope with small structural elongation and large elastic modulus should be selected. Normally metal core wire rope construction.
