[0029] The preparation method of directly using hot-melt steel slag glass ceramics is as follows:
[0030] a. Use a certain amount of auxiliary materials: quartz sand, aluminum stone powder, soda ash, barium carbonate, and titanium oxide are added to the steel slag. The mass ratio of these auxiliary materials to the steel slag is 35:100; the applicable chemical composition of the steel slag Range: SiO 2 (20wt%wt%), Al 2 o 3 (8wt%), CaO (55wt%), MgO (7wt%), Fe 2 o 3 (10wt%); the specific addition amount of auxiliary materials needs to refer to the composition of steel slag in actual production. It is necessary to ensure that the chemical composition of the molten glass after mixing is within the following range: SiO 2 (55wt%), Al 2 o 3 (8wt%), CaO (16wt%), MgO (1wt%), BaO (8wt%), Na 2 O (6wt%), Fe 2 o 3 (5wt%), TiO 2 (1 wt%).
[0031] b. Transport the steel slag with a certain quality in liquid state through the steel slag transport tank 1 to the front transition po...

[0036] a. Use a certain amount of auxiliary materials: quartz sand, aluminum stone powder, soda ash, barium carbonate, and titanium oxide are added to the steel slag. The mass ratio of these auxiliary materials to the steel slag is: 48:100; the applicable chemical composition of the steel slag Range: SiO 2 (23wt%), Al 2 o 3 (6wt%), CaO (52wt%), MgO (7wt%), Fe 2 o 3 (5wt%); the specific addition amount of auxiliary materials needs to refer to the composition of steel slag in actual production. It is necessary to ensure that the chemical composition of the molten glass after mixing is within the following range: SiO 2 (58wt%), Al 2 o 3 (5wt%8), CaO (20wt%), MgO (2wt%), BaO (6wt%), Na 2 O (4wt%), Fe 2 o 3 (4wt%), TiO 2 (1 wt%).
[0037] b. Transport the steel slag with a certain quality in liquid state through the steel slag transport tank 1 to the front transition pool 3 of the steel slag melting furnace and throw it into the glass kiln feeding port through the refrac...

[0042] a. Use a certain amount of auxiliary materials: quartz sand, aluminum stone powder, soda ash, barium carbonate, and titanium oxide are added to the steel slag. The mass ratio of these auxiliary materials to the steel slag is: 58:100; the applicable chemical composition of the steel slag Range: SiO 2 (25wt%), Al 2 o 3 (2wt%), CaO (48wt%), MgO (7wt%), Fe 2 o 3 (5wt%-); the specific addition amount of auxiliary materials needs to refer to the composition of steel slag in actual production. It is necessary to ensure that the chemical composition of the molten glass after mixing is within the following range: SiO 2 (60wt%), Al 2 o 3 (5wt%), CaO (21wt%), MgO (1wt%), BaO (5wt%), Na 2 O (3wt%), Fe 2 o 3 (4wt%), TiO 2 (1 wt%).
[0043] b. Transport the steel slag with a certain quality in liquid state through the steel slag transport tank 1 to the front transition pool 3 of the steel slag melting furnace and throw it into the glass kiln feeding port through the refrac...
