Zhangjiagang Hailu Annular Forgings Co., Ltd, founded in 1991, is one of the earliest specialization enterprises for mainly producing annular forgings, special section ring forgings, tire mold forgings, free forgings. The present annual output is up to 20,000 tons, and annual sales amount to 150 million. The company is capable of producing over one hundred kinds of nine big categories of steel such as alloy steel, stainless steel, bearing steel and high temperature alloy steel, and capable of producing various annular forgings under dia.3500mm, disk forgings (or with hole), axis and step-axis forgings, tube forgings, gear wheel forgings, flanges and tire mold forgings. These products have been widely used in areas including petrochemical industry, engineering machines, metallurgy, ship building, tire mold, transport vehicle, wind electric power generation etc.

  Zhangjiagang Hailu Annular Forgings Co., Ltd carries out the quality guideline, which is “put customers first, seek products perfect, improve continuously, and make enterprise stronger through qualityâ€? and then creats the hailu famous brand and enterprise image, and also be appraised as Reliable Quality Product and High-Quality, High-Service, and High-Credit company in Jiangsu province in 2004. The company not only has passed ISO90001:2000 Quality System Certificate in 1997 but also has reviewed every year from China Xinshidai Quality System Certificate Body, and established a better quality control system.

  Zhangjiagang Hailu Annular Forgings Co., Ltd catches up with and surpasses advance world levers , and promotes quality upgrade, seek products perfect and service high. Since 2000, the company has cooperated with some famous brade companies like Baosteel Group Shanghai No.5 Steel Co., Ltd. (No.5 Steel Corporation). The company has explored into various fields of aerospace, aviation, nuclear power, foreign trade and so on, such as Chengdu Aero-Engine(group) co., ltd, Shenyang Liming Aero-Engine Group Corporation, American GE company, and Qinshan Nuclear Power Station 。In recently years, with the development of the wind power industry, the company aims at the market of slewing bearing ring and bearing ring for the wind power industry, ,and exerts to develop the kind of the forgings with 42CrMo4 matetial. Due to the high quality and high mechanical properties, it begin exporting large quantities to European markets,and will reach 10,000 tons in 2007.

  To satisfy customer needs, Zhangjiagang Hailu Annular Forgings Co., Ltd has recently developed various heteromorphy annular forgings.This heteromorphy annular forgings refer various fields, including: each size hubbed flanges, heteromorphy gear ring for engineering machinery, heteromorphy forgings for grab, rims for railway and mining machinery, rolling ring for concrete mixer, heteromorphy forgings for rubber tire mould and large bearing rings etc. It have more advantages than common annular forgings (rectangle section) because of non-rectangle section. The rough section of heteromorphy annular forging could furthest satisfy the part shape required by customer, so could farthest save and shorten machining time, reduce energy consumption, then save the cost for customer to a certain degree, so be deeply welcomed by customer.

  Zhangjiagang Hailu Annular Forgings Co., Ltd, according to continual improvement’s request, perfects the quality control system and strictly draws up the quality handbook, the procedure document and the quality plan, the quality guarantee outline criterion running. Besides, the company arranges production and delivery according to advanced standards from famous world brands, such as American “caterpillar “company, England “LRâ€?company etc.Moreover, it establishes and operates the quality goals responsibility system, strictly technically supervises and measures in product realization process, and effectively monitors and records in special process like heating and heat treating. In addition, the company defers to the 6S standards and ensures safe, civilized and clean production.

  Zhangjiagang Hailu Annular Forgings Co., Ltd enlarges the quality resources investment. The company not only renews and transforms the original equipment including dia. 3000 mm full automatic numerical control mill machine, 1600 tons water press, 3 tons electricity liquid hammer, and several thermocouple control gas heaters, but also perfects heat treatment lines ,composed of the precise temperature-controlling pit furnace: moderate temperature pit batch-type furnace and chamber high –temperature car-bottom furnace and  fuel car-bottom furnace, and mechanical production lines,such as numerically control lathe, vertical lathe, drill machine etc, and also the physical and chemical analysis equipments and machine for UT. And the company can strictly make them maintenance, verification and renewal in accordance with the standards, and then ensure them to reach the requests of the product quality promotion and the quality control system.

  In 2007, the second annular forging production line with a total investment of 40 millions Yuan adds dia. 4500 mm full automatic numerical control mill machine and 3500 tons oil press. Arriving at the beginning of 2008, the capacity of the two production lines is: the annual output is up to 35,000 tons and the furthest weight of single forging is up to 6 tons, and meet customersâ€?demands.
