In the past few years,the production and operation situation of Chinese steel industry has been plagued by many troubles such as production overcapacity,shrinking market,declining product prices and rising cost of raw materials,which have been increasingly harsh for Chinese steel industry.It has become an inevitable strategic choice for steel enterprises to reduce production costs by upgrading rolling technologies and production equipments,as well as to increase value-added products by means of products RD.Several advanced rolling technologies,including the endless rolling technology,asynchronous rolling technology,thin strip casting technology and some new process technologies of medium plate were introduced as the latest development of products RD,by taking marine engineering steels,energy engineering steels and modern vehicle steels for examples.It is argued that only technological progress is the decisive force to promote sustainable development of Chinese steel industry.
