We report a multipurpose furnace designed for studies using synchrotron radiation on polycrystalline materials, namely, metals, ceramics, and (semi)crystalline polymers. The furnace has been designed to carry out three-dimensional (3D) x-ray diffraction measurements but can also be used for other types of synchrotron radiation research. The furnace has a very low thermal gradient across the spe...

This paper mainly emphasizes development of a multifluid blast furnace model and its application to simulate several innovative ironmaking operations. At first, the development process and framework of the model are briefly introduced. Then, model simulations on hydrogen bearer injection show that the enhancement of hydrogen reduction brings the improvement of furnace performance, especially fo...

Gas permeability in a blast furnace is directly influenced by the burden profile, which is the result of the charging angle collocation. An obviously increment in both iron-making productivity and furnace campaign life will be observed in a high heat utilization furnace with uniform gas permeability. An online burden profile measuring device without gas leakage risks and heavy maintaining load ...

This reaffirmation of teachers has been a leading factor in the development of recent strategies for school improvement The reports by the Carnegie Task Force and the Holmes Group are two prominent examples of proposals aimed specifically at problems within the teaching profession. These reports are significant in that they have helped place teaching squarely at the center of current educationa...

The technological process for manufacturing seamless steel tubes in the Sisak Rolling Mill includes the heating of the charge for processing in the hearth-rotating furnace. Description of the furnace and its operation can be found in literature 1 . In the process currently applied for producing the tubes with the outer diameter of 168.3–356.6 mm the temperature is between 1280 and 1300 °C 2 . T...

We revisit the far from equilibrium escape problem across a fluctuating potential barrier that is driven by asymmetric, unbiased dichotomous noise. Our closed analytical solution for arbitrary noise strengths reveals new aspects of the so-called ‘‘resonant-activation’’ effect and leads to interesting implications regarding far from equilibrium or externally controlled chemical reaction processe...

The present paper reports a statistical analysis of the performance of the blast furnace number X at the Bhilai Steel Plant over a period of sixteen years with the special reference to the quality and consumption of sinter . The variation in basicity and consumption of sinter, for the blast furnace data considered , is wide. The range of data covers high level to almost nil amount of raw limest...

INTRODUCTION This report presents the results of two trials conducted with the Blast Furnace Granular Coal Injection System at Bethlehem Steel Corporation's Bums Harbor Plant. The trials were conducted using granulated and pulverized high volatile coal from Colorado. The first trial was conducted to quantify the effect that a high volatile western coal, Colorado Oxbow, has on the blast furnace ...
