Limestone For Blast Furnace - niepamietnik.pl

2020-3-11  Blast furnace slag is a mixture of silica and other non-ferrous metals in iron ore, coke ash and limestone auxiliary materials used as reducing materials. Because its specific gravity is less than pig iron, the slag rises to the top of pig iron during heating, which is convenient for separation and recovery.

Re: Limestone for blast furnace

I need to come up with something to represent limestone that is ready to go to the furnace. First, I need to know what it looks like. Is limestone the same color in Pittsburgh as the rest of the country? Is it crushed, or sorted, or washed before being sent to the mill? Is there a product out there that I can use that is appropriate for HO scale?

2017-7-7  During the production of iron by blast furnace (BF) route, limestone is added either in the process of sintering or as a direct feed in the blast furnace. Limestone is normally added during ironmaking for obtaining either neutral or slight basic BF slag. Addition of limestone through sinter is more preferred route since CO2 of limestone is driven out during the sintering process.
