【Abstract】 In this paper we have discribad the development of concave shape row of silver-copper al-loy in use for 0.1 million and 0.2 million kilowatt turbogenerator rotors by the use of precise cold form process, given out that practical pass system for precise cold rolling which is used in batches production and the property of its produts reach the international standard. We have also given out the test results of rolling load, the microstructure and properties of produets and the main points of the rolling process, presented the evaluation of the products and the process, and practical situation of the equipment.更多还原
