Building collapses and residential elevator accidents caused by disasters continue to occur. At the same time, steel bars are widely used in various fields, such as houses, bridges, railways, roads, tunnels, etc., as skeleton materials for concrete structures. However, there are no mandatory standards

The steel wire rope is a spiral steel wire beam that stretches the steel wire that meets the requirements of the mechanical performance and geometric dimensions according to certain rules. The wire rope is composed of steel wire, rope core, and fat grease. The steel wire rope is first twisted from the multi -layer steel wire, and then the rope core is centered, and a certain amount of stock twist into a spiral rope. In the material handling machinery, the use of improvement, traction, tightening and carrying. The strength of the wire rope is high, the self -heavy, the work is stable, and the work is not easy to break suddenly, and the work is reliable.
Galvanized steel wire ropes will cause different degrees of wear after a long period of use. According to the positioning position of the wear, it can be divided into external surface wear and internal surface wear. The wear caused by friction caused by common objects such as galvanized steel wire r
The company's main products include PU synchronous belt steel wire ropes, automotive flexible steel wire ropes, control steel wire ropes, aviation steel wire ropes, copper-clad steel wires, phosphated steel wires for optical cables, phosphated (galvanized) steel strands for optical cables, galvanized steel wires, etc.After years of research, exploration, and development, the company has formed a complete set of technologies and process software, and the physical quality of its products has reached the international advanced level.The company owns and has strong independent R&D and manufacturing capabilities.With a complete and scientific quality management system, its products are sold at home and abroad. Steel rope products are widely used in metallurgy, machinery, shipbuilding, petrochemical, construction, fishery, ports and other departments and have received unanimous praise from the outside world.
The market for steel wire ropes for PU synchronous belts is still very impressive. At present, the industries in which PU synchronous belts are used in the market are (arranged in descending order of usage): ceramic industry, glass industry, automatic door and window industry, knitting industry, home appliance industry, photovoltaic industry, packaging industry and other industries.The small working difference of the endless belt makes the machine more stable during high-speed operation.Polyurethane ring-type power belts have small tolerances and can ensure the accuracy of thickness and length.The above characteristics make the polyurethane endless power belt have high physical and chemical stability.Polyurethane seamless timing belts are suitable for high-strength, high-precision and even high-speed transmission systems.The PU synchronous belt uses steel wire or glass fiber as the strong layer and is covered with a polyurethane endless belt or open belt. The inner circumference of the belt is made into a tooth shape so that it meshes with the toothed pulley.When driven by synchronous belt, the transmission ratio is accurate, the force on the shaft is small, the structure is compact, oil resistance, wear resistance, aging resistance are good, the general operating temperature is -20
The rubber is produced using imported raw rubber. The main properties of the product are: the product is non-toxic, odorless, environmentally friendly, resistant to aging and high temperature, heat-resistant, and has stable performance. It can maintain good performance in summer and winter.The steel frame is made of three composite materials, which is not easy to deform and shrink, has firm assembly and good sealing performance.EPDM sealing strips are used for doors, windows, and curtain walls. The product has good elasticity, resistance to migration, and can effectively block noise, dust, and weatherproofing.Copper-clad steel wire is easy to leak, wear-resistant and corrosion-resistant.The mesh section is trapezoidal.The gap is narrow at the top and wide at the bottom.It is a screen bar made of cold-rolled stainless steel wire. The support bar is welded by automated mine screen production equipment. The screen seams are uniform, the welding quality is stable, the opening rate is high, the service life is long, and it has high strength and rigidity. and carrying capacity, it can be made into various shapes of steel screening and filtering devices.The basic process of medium and high frequency annealing of stainless steel: Using medium and high frequency induction heating method, the temperature of stainless steel is quickly raised to about 1050℃ (specific temperature
Continuous wear and adhesive wear occur in the actual contact friction parts. Abrasive wear is caused by the adhesion and incorporation of dust and abrasives. If the steel wire rope is exposed to moisture, acid, and alkaline gas environments, it will cause corrosion and chemical erosion. Due to overloading, Impact or excessive bending will change the structure of the steel wire and reduce its strength, causing fatigue. This is a form of gradual accumulation and sudden damage that is not easy to detect.Because the specific pressure between the quilt wires, the steel wire, the rope sheave, and the drum is too high and the oil film strength is insufficient, marks and deformation may occur.Wear caused by frictional heat from direct contact with metal.Lubrication and maintenance (1) How to add lubricating oil.Diffusing method, when diffusing, first clean up the dirt, dust, sludge, etc. in the air of each strand of the wire rope with superheated steam or compressed air and a steel brush, and then put it into an oil bath to diffuse. The oil used should be heated to 50 left and right to allow for penetration.The infiltration interval is once every 3 months under normal temperature conditions.return
