The study on electric steel used for high efficiency compressor has a great actual applied value.The preparation technology of non-oriented electric steel AW23 of ANSteel at present is researched in the paper. The methods of technology optimization in the Laboratory and advanced development in the factory are chosen. The research means of metallurgical structure observation, TEM analysis, texture test and magnetic properties measurement are adopted. Cold rolling electric steel used for high efficiency compressor is researched as follows:1)designed by composition to low core loss;2) adopting system of high temperature coiling in stead of normalizing technology in hot rolling process to obtain favored original structure state;3)optimizing parameters of cover annealing technology and flattening technology.4)The whole advanced development project for cold rolling electric steel used for high efficiency compressor.Researches above draw a conclusion as follows:1) High temperature coiling and other correlative technologies in stead of normalizing technology in hot rolling process are adopted to achieve origin texture form of hot rolling needed.2) Low temperature annealing and flattening technique of great percentage of reduction are adopted to ensure user excellent magnetic properties after punching and annealing, core loss P_(1.5)≤4.0 W/kg and magnetic induction B_(5000)≥1.69T.3) The advanced development in the factory has been progressed by designing components and using optimum technology parameters. Properties of product are that core loss P_(1.5) is not more than 4.0 W/kg and magnetic induction B5000 ranges from 1.71T to 1.73T, which reaches the aim of research and development. dimensional accuracy of electric steel plate direct influence users' installed result and product's magnetic property externalization. actual measure steel reel head and tail's thickness deviation of trial manufacture products reach≤10μm level; the same plate's difference of width specification 1000mm's products reach≤10μm, meet user's service conditions.
     4) The statistical data of batch production in the factory and the actual applied instances show that the design of the product is reasonable, the technology is feasible and properties of product reach high efficiency requirements for advanced compressor manufacturing in the market.
