The stream of slag draws the mixture down into the slag.

The slag is retained in the reservoir (36) and discharged out of the slag opening (52).

For manufacturing elements made of slag material, in particular of blast furnace slag, the slag is poured, shaped and solidified.

The conveying lockhopper is configured to receive slag from a gasifier, simultaneously extract and dewater the slag, and expel the processed slag directly into an awaiting container suitable for carrying the processed slag away.

By monitoring the steel/slag interface, slag contamination can be avoided.

After the required degree of transformation, the fluid slag is discharged through the slag run-off outlet (11).

The steps for such purification involve introducing molten slag into a heat vacuum chamber (10), whereby the heat and vacuum oxidize the slag.

In this document there is disclosed a method for purifying slag.

The slag is separated into slag and a metal by means of the crushing that occurs due to impact when the slag falls due to the rotation of the housing and by the destruction caused by the rapid cooling of the slag.

The set slag drops into the water tank.

The resultant oxidized slag is hardened and comminuted, the paramagnetic portions formed then being separated magnetically and dissociated from the de-chromed slag.

The slag is then separated from the melt, with the contaminated substances located in the slag.

Steel slag can contain iron and thus have a higher density than some other types of slag.

The slag is reduced, yielding a type of blast furnace slag with improved hydraulic properties.
