Pilot Plant Studies on the Production of Metallurgical Coke

Coke is an essential raw material for the manufacture of iron by the conventional blast furnace technique. Due to the paucity of reserves of high grade, coking Coals suitable for the production of metallurgical coke a rational use of these types of coals and utilization of increasing proportions of substandard coals for coking are receiving seriqus consideration in most countries in the world

The Problem of Supply of Coal for the New Steel Plants

WITH depletion of the lower ash, good coking coals occurring in the ripper seams of the Jharia coal field, which were the principal sources of supply of coking coals for the steel plants in the private sector, atte-ntion was focussed on the need for beneficiation of the higher ash Jharia coals. Three commercial coal washing plants (185 tons/hr. total capacity) were installed in recent years for supplying washed coal to the existing steel plants

The size requirement of Blast Furnace Coke (1)

THE exact specification for the physical characteristics of blast furnace coke remains controversial even today. But the advantage of using coke of consistent quality and is closely graded size has been generally recognised. Greater emphasis is being given on the size distribution of the coke rather than on the strength of the coke as assessed by conventional tests. It is believed that after the coke has been charged in the furnace, its strength is probably of less consequence, the size consistency being the dominant factor

Insulator superconductor transition on solid inert gas substrates

We present observations of the insulator-superconductor transition in ultrathin films of Bi on solid xenon condensed on quartz and on Ge on quartz. The relative permeability $\epsilon_{r}$ ranges from 1.5 for Xe to 15 for Ge. Though we find screening effects as expected, the I-S transition is robust, and unmodified by the substrate. The resistance separatrix is found to be close to $h/4e^2$ and the crossover thickness close to 25 $\AA$ for all substrates. I-V studies and Aslamazov-Larkin analyses indicate superconductivity is inhomogeneous. The transition is best described in terms of a percolation model.Comment: Submitted to LT23 Proceeding
