UNIT FOR OBTAINING BROKEN SLAG FROM MELT Russian patent published in 2015 - IPC C22B7/00 

FIELD: technological processes.

SUBSTANCE: invention relates to a unit for obtaining broken slag from a melt. The unit includes devices for receiving and distributing melted slag, cooling and sizing of the broken slag in a reservoir rotating about the horizontal axis, assembled of grates, with balls located in it, a device for the removal of a steam-gas mixture and a device for broken stone after-cooling and transportation. The unit is provided with a shaper installed at the slag outlet of the reservoir assembled of the grates and made in the form of two water-cooled rolls with a horizontal rotation axis, which are rotated opposite to each other; with that, surfaces of the rolls of the shaper are spring-loaded and form cube-shaped cavities of different sizes at connection.

EFFECT: increase of the yield of broken stone of a more manufacturable cube-like shape with a limited content of cube-shaped and shell-like grains; decrease of the surface temperature of the broken stone grains and the improvement of its strength properties.
