in the present work the recrystallization behavior of deep drawing grade al-killed low carbon steel sheets produced by mobarakeh steel plant (msp) has been studied. salt bath isothermal annealing has been applied to cold rolled samples and the resulted microstrucrures have been compared with the microstructure obtained from the box annealing process in msp. it is found that at 635 and 700ºc the...

Models of vintage-capital learning by doing predict an initial fall in productivity after the introduction of new technology. This paper examines the impact of new technology on plant-level productivity in the Japanese steel industry in the 1950s and 1960s. The introduction of the basic oxygen furnace was the greatest breakthrough in the steel refining process in the last century. We estimate p...

The converter gas, especially Linz Donawitz converter gas (LDG), is one of the most significant secondary energy resources in a large scale steel plant. For such a thing, the accurate prediction for the gas tank levels largely contributes to the energy optimization operations. Taking the LDG system of a steel plant in China into consideration, a regression model based on the Granular Computing ...

We studied the spatial distribution of cancer incidence rates around a large steel plant and its association with historical exposure. The study population was close to 600,000. The incidence data was collected for 1995-2006. From historical emission data the air pollution concentrations for polycyclic aromatic hydrocarbons (PAH) and metals were modelled. Data were analyzed using Bayesian hiera...

The layout of chemical plants has to take into consideration boundary conditions and requirements of many different engineering fields. In order to assist the design engineer at an early stage during the extended basic engineering, a system for computer aided plant design has been developed. It contains modules for •extended equipment models including equipment related piping and areas for main...

The design of system for operative planning of blast furnace production process in VSŽ inc. Kosice A system for operative planning of blast furnace production process is described in the paper. The suggested system is based on the use of a new hierarchy of operative plans, consisting of one-month plan, (7+3) days plan, and 24-hour plan. The system allows smoothing of production process at the b...
