Changes in the sectors of iron, steel and non-ferrous metals and the current development of technology forces the steel mills increased productivity, reduce production costs while ensuring to obtain a product with the required properties and to improve the competitiveness of enterprises in the global market. Currently, the most popular in meeting these requirements, enjoys a method of integration which combines individual operations into one integrated whole. The use of modem, perfectly designed, fully automated design of mechanical, hydraulic and measurement allowed us to achieve an innovative line of production. This article presents the general characteristics of the steel industry and a description of the latest integrated technology currently used in foundries and rolling mills. It also presents examples of the use of integrated technologies in metallurgy and the effects of economic, environmental and quality resulting from their use on an industrial scale.展开更多

We summarize the latest progress in the development of public housing in post- reform China and investigate the driving forces behind these developments. A close examination of the public rental housing program in Shanghai helps to show that the recent revival of public housing in Chinese cities is mostly driven by the desire for economic growth. We conclude that the state provision of housing could be a short-run state remedy to alleviate economic imbalance and social inequality. However, in the long run China needs to seek more effective solutions to solve the low-income population＇s housing affordability problems.展开更多
