Steel-making and continuous/mould casting are the key processes of modern iron and steel enterprises. The continuous and mould casting schedule of mixed whole/half charging plan is the bottleneck for the steel-making and continuous/mould casting process. However, it is very difficult to find a solution against the characteristics and complicated environment. This paper proposed a heuristic batc...

Steel industry is one of the leading industries in the world. Today it is also one of the fundamental and strategic industries of the world. Per capita production and consumption amount of steel are used as a criterion for evaluation of country development. Furthermore, attention to technological innovations is assumed so much crucial to access the international markets of steel industrie...

Grate bar is an industrial part which is used in the indurating furnace of an iron ore pelletizing plant. Steel part ofthe grate bars are expected to have high resistance to atmospheric oxidation because of its contact with hot gases(up to 920 °C) during the normal operation of the process. In this study, different samples from several sections ofused grate bars with apparent ...

Under the circumstances of low-carbon economy, the theoretical applications of the green supply chain management of steel and iron manufacture are to reform and innovate the present manufacturing process, enhance the controlling and reclaiming, and recycling using of the waste steel and iron, steel slag, and dust emissions, establish the green supply chain structure oriented to the cycle of “re...

This paper reports the results relating to the following four subjects: i) current status and future prospects of iron and steel production in China; ii) equipped plantsize and operating condition of blast furnaces that sustain Chinese big steel production; iii) trends of demand and supply of iron ore and coal for blast furnaces; and iv) challenges and problems entailed by production increases....

In view of the development and the need for fault diagnosis in industries, remote diagnostics technology, based on intranet and Internet, is deemed an inevitable trend. This article presents the architecture of a multi-tier, complex remote diagnostics system by applying CORBA. Functionality for each tier of the architecture is elaborated. A remote diagnostic system is then implemented and appli...

Roller is a key component of milling machine in iron and steel industry, with the development of industrial wireless technology. The online predictive maintenance of the roller plays an important role in effective production. But the harsh working environment – spray of cooling liquid, moving, high temperature and heavy shelter – cause low quality of wireless communication and need high reliabi...

Nigeria is blessed with abundant iron ore deposits of nearly 3 billion tonnes and other basic minerals for steel production including coal and limestone. Yet the Nigerian steel sector has collapsed principally due to shortage of raw materials particularly iron ore for the integrated steel plants and billets for the rolling mills. The privatization of the steel sector that was done in 2004-2005 ...

environmental degradation and economic growth are two important proofs in sustainable developmentwhich are followed by steel industry. in this case, energy and environmental damages as sustainabilitypatterns of environment have been investigated in three different dust collectors to select the mostenvironmentally suitable dust collector for electric furnace. in this article, the consumption amo...
