Disposing Of The Slag ChestofBooks

In the early days of the blast-furnace the slag was handled as clinker or ashes, and this method of procedure survived until very recent times in the crane-operated shovel, fork, etc., which I have described in a previous chapter as adjuncts to charcoal furnaces in the seventies and which were used to clean out and "work down" the furnace very much as we find it necessray to do with the

The possibility of fly ash and blast furnace slag disposal

2019-8-12  The possibility of disposing of fly ash (FA) and blast furnace slag (BFS), which are environmental wastes, by using them as substitutes in portland cement was examined in this study. Portland cement (CEM I), FA, BFS, CEN standard sand, and water were used in the production of mortars. Blended cements were obtained by substituting FA, BFS, and a mixture of FA and BFS

What is Blast Furnace Slag? Definition from Trenchlesspedia

2021-3-4  Blast furnace slag is a non-metallic residue usually obtained from steel plants or from the reduction of ores in a blast furnace. It is used as a mud cake modifier for the cementing of oil and gas wells. It has been found that using a slag mix for cementing is beneficial economically and technically as well as better for the environment than

The Carbon Cost of Slag Production in the Blast Furnace:

2017-8-27  The idea is simple but may be a bit complicated to bringinto practice because the slag quantity in the blast furnacehas an impact on the overall functioning of the blast fur-nace process. If the carbon demand of the blast furnacechanges, so will be the amount of waste gases produced.Since the carbon in this waste gas is not fully consumed, itis necessary to determine exactly what changes to the blastfurnace gases will happen while the hot metal production isbeing kept constant. It is common practice in carbonaccounting for the steel industry to substitute steel wastegases for natural gas when it leaves the shop limits becauseit hugely simplifies the accounting of waste gases in otheractivities than the ones where the gases were generated. Soa credit for an equivalent quantity of natural gas corre-sponding to the change in blast furnace gas can be attrib-uted to the process. In LCA terms this can be viewed as‘‘system expansion.’’Next to the changes in the blast furnace itself there isalso a need to look at some upstream emissions. Tomaintain a blast furnace
