Detection Scope
Scope IntroductionCarbon steel wire rope
is made by twisting high-quality carbon structural steel wire as raw material.< p> Stainless steel wire ropeis manufactured and twisted from stainless steel wirePhosphate coated wire ropeis abbreviated as phosphating wire rope. The phosphating film of the rope making wire weighs 3-60 grams/square meter. After phosphating、 the wire is not subjected to cold drawing before twisting、 and the strand、 steel core、 and wire rope are directly twisted. The phosphating film can improve the wear resistance and corrosion resistance of the rope making wire surface、 effectively suppressing the occurrence of fretting fatigue< p> Galvanized steel wire ropeThe protection of the galvanized layer on the steel wire belongs to anodic protection、 and the thicker the galvanized layer、 the stronger the anti-corrosion ability. 3. Coating plastic steel wire rope、 coating a certain thickness of plastic on the outer surface of the steel wire rope or the outer surface of the strand rope、 including polyethylene、 polypropylene、 polyurethane、 etc< p> Smooth steel wire rope is a rope making steel wire obtained by cold drawing raw materials after heat treatment and surface preparation. The steel wire is no longer subjected to any surface treatment and is directly twisted into strand ropes、 steel cores、 and steel wire ropes< p> Single strand rope、 also known as single twisted rope、 is made by twisting the rope making steel wire around the central wire or hemp core、 and can be twisted into one or multiple layers of steel wire< p> Double twisted ropeis a widely used variety of steel wire rope、 which is made by twisting a double stranded rope around the rope core (steel core or fiber core) and can lay one or multiple layers of steel wire< p> Triple twisted ropeis made by twisting double twisted rope as a strand around the rope core. It is mainly used for thick gauge steel wire ropes with a diameter of over 60mm.Point contact steel wire ropes
have the same diameter of steel wires in the strand、 and the twist angle between each layer of steel wire is the same、 with different lay lengths. Therefore、 the inner and outer layers of steel wire intersect with each other、 forming a point contact state< p> The wire rope in line contacthas the same lay distance and different lay angles for each layer of wire in the strand、 and the inner and outer layers of wire are in contact with each other on a spiral line、 presenting a line contact state. Under the same usage conditions、 the service life of wire contact wire ropes is longer than that of point contact wire ropes< p> Compaction type steel wire ropes were originally called surface contact steel wire ropes. During the laying process of steel wire ropes、 contact surfaces are formed between the steel wires through forging、 drawing、 etc.、 including strand rope compaction、 wire rope compaction、 and rope strand double compaction< p> The outer layer of the sealed steel wire rope is made of special-shaped steel wire、 including steel wire with a T-shaped S-shaped Z-shaped cross-section structure. The surface is smooth and has good wear resistance. Compared with other types of steel wire ropes of the same diameter、 it has higher tensile strength and can withstand lateral pressure. However、 it has poor flexibility、 complex technology、 and high manufacturing costs. It is commonly used as a load-bearing cable、 such as in cable cranes and aerial cableways< p>Testing items
