Combinating with the phenomena of excessive carbide mesh, micro-cracks and etc. in bearing ring forging parts becaus of cooling technology backwardness, study of new smart and controlled cooling technology and equipment to achieve cooling process automation, intelligent production process quality control, process equipment to ensure their quality. Through enterprise trial production testing, forging microstructure refinement after the cooling part, mesh carbide can be controlled in the following 2 to eliminate micro-cracks, shorten production cycles, lower costs, meet foreign bearing the company's supply requirements.

Wind power generation has developed fast in recent years, which not only alleviate the press of power energy, but also give the promotion of sustainable development for environment. China is rich in wind energy resources. The development of wind power in china has made marked progress, although there are some problems. This paper elaborates the importance of the development of wind power; provides an overview of the status of wind power generation in China and gives some suggestions for the future development.
