Recently,cast bronze Baosteel Special Steel Division, together with the development of Dalian Wafangdian Bearing Group 2 MW wind turbine steel spindle bearing success, bronze bushing and signed a supply contract of 100 tons, the product will soon be sent to Dalian.
ZWZ was founded in 1938, is the birthplace of China's bearing industry, China is currently the largest bearing manufacturers.dry bushing In recent years, aimed at the domestic wind power ZWZ huge potential market, the state encourages the development of wind energy,plain bearing nuclear power and other new green energy as an opportunity to vigorously promote wind power bearing, major equipment bearing the R & D prototype, in order to achieve a comprehensive import substitution. The group has a wind power bearing the brand "ZWZ", and for the world's top business quantities.
Last year, sleeve bushing a foreign wind power ZWZ bearing the user to make the strict quality requirements, requires the use of 2 MW wind turbine bearing steel, DU bushing bearing life to ensure that more than 20 years. At that time, the domestic steel mills are not a board for the materials to meet the quality requirements ZWZ. ZWZ Special Steel Division and has a good working relationship for many years,bushing ZWZ Special Steel Division on the high degree of confidence. Therefore, the two sides decided to jointly solve the problem, developing 2 MW wind turbine bearing steel, to replace imported products.
Development period,brass bushing the steel division, Shenyang and Dalian Baoshan Steel employees ZWZ several times the exchange of technical personnel. The two sides on the slab quality of life of the product research experiment, the formation of technology agreements,Mould guide plate from raw materials, smelting technology and other aspects of improvement. plasic bushing Through the cooperation of both sides, and 2 MW wind turbines developed a smooth steel shaft bearings.
