Recently,sleeve bushing Science and Technology Department experts in Qinghai Province, Xining Special Steel Company of Qinghai projects undertaken by "high-quality bearing steel with wind dry bushing power development" to the acceptance, experts believe that the research results reach the domestic advanced level.
bronze bushing Wind power generation is the construction of new energy development and the focus direction, as the wind turbine bearings, one of the important parts of the market cast bronze demand is expanding. However,brass bushing China's wind power production with the bearing still in its infancy. Xining Special Steel Company for the market demand, after three years of hard work, bearing in accordance with the structure of wind characteristics and working conditions, through control of oxygen content in steel, non-metallic inclusions control,plain bearing super-size ESR ingot remelting plasic bushing technology research , Mould guide plate super-size ESR ingot heating technology research, special studies, developed GCr15, GCr15SiMn, GCr18Mo, GCr15SiMo wind power with four high-quality bearing steel, to fill the gap. Currently, the series has achieved mass production, cumulative production of 1479.31 tons, production value of 15.745 million yuan, DU bushing with significant economic benefits.
