SU113767A1 - Hydro-granulator for metallurgical slag - Google Patents

Description

When using known methods for removing and transporting slag from blast furnaces and open-hearth furnaces, casting spans are cluttered with bowls and ladles, which complicates slag transportation.

In order to eliminate this drawback, it is proposed to granulate slag with a stream of water under pressure in a granulator located directly at the metallurgical unit, and then transport the granulated slag with water through pipes.

A characteristic feature of the proposed hydrogranulator is the use of a funnel in it, which ensures a uniform supply of slag into it.

The drawing shows the scheme of the proposed granulator.

A special granulator for slag discharge is installed near the metallurgical unit. The removable funnel 1 of the granulator has an opening that is designed to skip the normal amount of slag or metal, which prevents excessive amounts of slag from entering the granulator during an accidental release.

Once in the granulator, the slag stream or the metaclosis is crushed by a stream of water, the exit of the necks from the nozzle 2 under a pressure of 16-f40 atm, and is carried away to the pipeline 3, where the granulation ends. With the passage of the diffuser 4, the jet creates a vacuum inside the granulator, which prevents the formation of steam from the funnel / upward in the granulator. For this purpose, water is placed on the curtain 5 in the funnel and suction of steam through pipe 6 is provided. Water with granulated slag is discharged into the basin, from which the slag is removed by a clamshell crane or other mechanism.

Subject invention

A hydronucleator for metallurgical slag located directly at the furnace and equipped with a nozzle for supplying pressurized water, characterized in that, in order to ensure uniform supply of slag, the granulator is equipped with a funnel, the outlet of which is designed to pass the required amount of slag.
