The mineralogy of air granulated converter slag

 · The three largest granulated slag fractions are very similar. The overall C 2 S content is the same (41 to 44 wt ) but the βC 2 S content in the granulated converter slag increases with increasing granulated slag size fraction while the α H C 2 S decreases (from 28 to 22 wt ). This is likely an effect of the slower cooling of the larger slag fractions which allows for the

Slag Cement Questions

Slag cement is the hydraulic cement that results when molton slag from an iron blast furnace is rapidly quenched with water dried and ground to a fine powder. The rapid quenching ("granulation") "freezes" slag cement in a glassy state and imparts cementitious properties to the product when ground finely.

 · Each year approx. 400 million tons of blast furnace slag is produced worldwide with a tapping temperature of around 1 500°C. Currently the slag is granulated in wet granulation plants using large volumes of water and to date it has not been possible to utilize the remnant heat energy of the molten slag with approx. GJ of energy per ton.

Types of iron and steel slag NIPPON SLAG ASSOCIATION

 · In the same way as aircooled blast furnace slag converter slag is cooled slowly by natural cooling and water spray in a cooling yard. It is then processed and used for various iron and steel slag (converter) applications. Approximately 110 kg of slag is generated for each ton of converter steel. Electric arc furnace slag

Structural and durability properties of concrete made

 · Approximately 240 000 tons of GGCS are now being produced annually at Saldanha. CHARACTERISATION OF SLAG Slag consists mainly of silica and alumina derived from iron oxide ore and lime added as a fluxing agent. Rapid cooling of slag using water quenching produces a glassy material that is slowly reactive with water.

Liters To Metric Tons ConverterThe Calculator Site

Convert From Liters To Tons. Convert between liters and metric tons using this calculator tool. As explained in the article how to convert from volume to weight the metric ton is a unit of weight and the liter is a unit of volume. To convert between the two you need to know the density of the substance that you are trying to convert.
