The present invention relates to treating technology for converter slag with low basicity, electric furnace oxidizing slag and open-hearth slag and equipment thereof. The treating technology comprises the following steps: hot slag in various lump sizes is poured into a steel vessel (1), a valve (3) arranged on a drainage pipeline (2) connected to the steel vessel is closed, and the …
Based on the treatment of 1,000 tons of slag per day, production cost of treating quenched converter slag would be $1.85 versus $2.37 per ton of slow-cooled slag. The cost advantage of processing quenched slags results from elimination of the slow-cooling and crushing operations inherent in the treatment of slow-cooled slags.

(1) Thermal stabilization treatment: Mix slag with a certain proportion of cement, lime, etc., and undergo high-temperature treatment to convert it into harmless substances. (2) Pyrolysis treatment: Put the slag into a high-temperature furnace, undergo pyrolysis reaction, and ultimately convert into harmless substances.
The slag has not been fully melted in the early stage of blowing and the metal splash that is easy to occur during the slag back-drying period is one reason for the slagging at the furnace mouth, and the slag splashing of the remaining steel is another reason for the slagging at the furnace mouth; when the slagging at the furnace mouth is serious, the thickness It can reach more …
Incineration treatment involves placing the slag into a high-temperature furnace for combustion, ultimately converting it into ash and slag. The advantage of this treatment method is that it can convert waste into reusable resources, but the disadvantage is also obvious, as it generates a large amount of carbon dioxide and other harmful gases ...
