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...

The optimized blast furnace design is the prerequisite for low-carbon smelting. salamander depth and bosh angle are key parameters, which determine longevity. In this paper, physical mathematical force model of deadman cooling stave was established. relationship between operating parameters depth, as well angle, analysed, gas flow scouring curve proposed. following results were obtained: first,...

The purpose of this study was to evaluate the performance of porous vegetation concrete block made from blast furnace slag cement containing industrial by-products such as blast furnace slag aggregate and powder. The blocks were tested for void ratio, compressive strength and freeze-thaw resistance to determine the optimal mixing ratio for the porous vegetation block. An economic analysis of th...
