Design and application of digital management system for the sinter raw material plant
To solve the problems existed in iron and steel enterprise material plant, such as complex sources resulting in variety of materials, inaccurate inventory statistics leading to high cost, unpredictable external factors affecting material plant, etc., a digital management system is introduced in this paper. Firstly, the practical requirements and the process of material plant are analyzed. Based on the analysis, the new grid management and material balance methods are developed. Applying these methods, a new management system for material plant is designed, whose system configuration, hardware architecture, data flow, and functions of modules are introduced in details. Such system has been implemented in a large-scale iron and steel corporation sinter raw material plant. The operation results show that, this system has excellent capabilities and a promising application future in industries.
REVAMPING OF BF RAW MATERIAL YARD AT TANGSHAN STEEL
Main items of BF raw material yard revamping project are:material supply and return system matching with updating of one BF and one sintering machine,revamping of raw material yard and PLC control system to improve supply capacity,optimize the BF operation,increase availability of facilities,and use 90 70 PLC+CPU instead of SB+CPU for sintering
Social Health Insurance Reforms—Mid-Term Experiences of Poland and Russia
As a result of transition process to market economy, Poland and Russia have come a long way from a centrally planned budget for social security to an insurance-type model in the social sphere. After more than two decades of reforms, it seems essential to compare and evaluate the policy solutions introduced in terms of the reform goals achieved and exposure to current challenges. The paper presents an analysis and comparison of social health insurance reforms conducted in Poland and Russia since the beginning of the 1990s. Moreover, the current problems of and future challenges for health care financing systems are identified. The varied experiences of Poland and Russia over more than 20 years show mid-term lessons which could be useful to other countries, especially those that face socio-economic transformation, in their choice of strategy and the practice of similar reforms.
