Smelting. As ores move through the submerged arc furnace during processing it passes through a number of reaction zones. In the upper furnace zone the particulates are present as "loose charge" and product gas from the lower furnace consisting of principally CO and CO2 passes through this packed bed.
Thermal coal shortages have hit secondary producers. Rebar prices in the country have risen by over 40pc from a year earlier. "The problem of thermal coal shortage was the last nail in the coffin for secondary producers. We were already bleeding with the iron ore issues," said Steel Re-rolling Mills Association's chairman Vivek Adukia.
Intelligent automation for steelmaking. State-of-the-art production of high-quality steel requires standardized and reproducible processes.

A type of cold-rolling mill, the tandem mill imparts greater strength, a uniform and smoother surface, and reduced thickness to the steel sheet. Unlike the original single-stand mills, a tandem mill rolls steel through a series of rolls (generally three to five in a row) to achieve a desired thickness and surface quality.
US smelter-grade aluminium scrap prices rangebound. Prices for smelter-grade aluminium scrap were largely rangebound on Thursday December 9, with sources citing slowed end-of-year market activity. The market is "very quiet for year end," one market source said December 9, adding that there's "only a short time until Christmas/New Year.".

About. The mark of true leadership lies in the ability to perceive the impossible. The simple act of seeing beyond the ordinary is what separates the average from the exceptional.
as on-site fuel. Coal has a wide range of moisture (2-40%), sulfur (0.2-8%), and ash content (5-40%). These can affect the value of the coal as a fuel and cause environmental problems in its use. The depth, thickness, and configuration of the coal seams determine the mode of extraction. Shallow, flat coal deposits are mined

In coal milling for power stations, a 'closed-loop' process is used in which the rejects from the classifier are returned to the mill for regrinding. In VSMs, the re-circulation loop is within the mill, but some mill types would have an external loop. In fact, there are a number of re-circulation loops within a mill system.
