Hot-rolling pulleys have strong professional requirements for manufacturing.The most excellent hot-rolling machine in the industry is required; Ar+C02 gas-protected automatic welding is required for welding; technicians must have qualification certificate; the main technical performance parameters must meet the national standard design requirements so that the product finally meets the user's requirements.
“Changjiang” brand hot-rolling pulley is a new generation product after casting pulley and duel radial pulley. The company is an expert in hot-rolling pulley manufacturing, and the advantages of hot-rolling pulleys are outstanding:
1. Reasonable structure, high strength and light weight, 40% lighter than casting pulleys of the same specification.
2. The surface of the rope groove is smooth and wear-resistant, and the hardness is greatly improved after the quenching treatment, thereby prolonging the service life of the pulley by 1-2 times.
3. The cutting amount is reduced by about 70% compared with the casting pulley, thereby saving a large amount of materials, reducing the processing time, and eliminating deformation after welding.
4. According to customer needs, produce different specifications of the product: from ø280mm-ø2000mm
5. The manufacturing cycle is short (hot rolling pulleys increase the efficiency of 10-20 times than casting pulleys), and at the same time adapt to single or mass production.
6. High precision: The radial runout is 1/1000D (D-pulley diameter), which exceeds the 5/1000D specified by the West German standard DIN15063-77, and the lateral jump is 2/1000D exceeding the Japanese standard 3/1000D.
Hot rolling pulley from Xinxiang Changjiang Hoisting Machinery Co., Ltd. has been widely used in lifting transportation, port loading and unloading, shipbuilding, grab, pulley, mining machinery, metallurgical machinery, construction and installation, etc., meeting the needs of various users.
