Iron oxide occurs as a dust in many industries apart from iron-ore mining. It is found in silver polishing, electric welding, and boiler scaling, as well as in the more obvious metal grinding, fettling, and blast furnace working where it may be mixed with varying amounts of silica. Some still consider iron oxide a harmless dust (Baldi, 1952) while others think that, like coal, it can produce ch...

The article presents the solution adopted in an existing blast furnace with only two safety valves to minimize dust and gas emissions atmosphere, case of emergency relief due abnormal overpressure during operating issues process. Before implementation system, several openings bleeder were observed: These led sensitive pollutant emissions, also terms acoustic visive events, high impact on surrou...

High pellets ratio operation forced by burden material restrictions at Kobe Steel resulted in the development of a center coke charging process based on centralized gas flow principle. This methodology produced a novel approach to burden distribution, coal combustion and pellets operation, in which these processes are viewed as part of a chain reaction. As a result of these developments, furnac...

The purpose of this study is to investigate porous vegetation concrete formed using the industrial by-products blast furnace slag powder and blast furnace slag aggregates. We investigated the void ratio, compressive strength, freeze–thaw resistance, plant growth and water purification properties using concretes containing these by-products, natural jute fiber and latex. The target performance w...

Limestone filler is a raw material that is already used in several applications like paints, bricks, bituminous mixtures...etc. Moreover, and particularly in Belgium, classical additions for concrete like fly ashes and granulated blast furnace slags are becoming rare; there is a need for new additions that could have a positive effect on the properties of the fresh and hardened cementitous comp...

Abstract In this study, iron concentrate and blast furnace dust were used as raw materials, graphite was a reducing agent for mixing briquetting. The briquettes roasted in high-temperature tube at different temperatures held certain time to simulate the pre-reduction sintering process. effects of content, reduction time, temperature on removal rate zinc, potassium, sodium metallization sintered...
