Embodiment 1
[0047] In this embodiment, modified open hearth furnace slag is used and obtained through the following pretreatment steps:
[0048] Step 1: Select open-hearth slag with an aging time of 5 months, and crush it with an impact crusher or an autogenous mill to obtain fragments with a particle size of less than 5mm;
[0049] Step 2: Use magnetic separation to remove some of the metal iron and RO phase slag with high FeO content to obtain open hearth furnace slag with suitable particle size and less impurities;
[0050] Step 3: Soak the open hearth slag with 10% NaOH solution and heat it for 7 minutes to remove surface oil stains, and then wash it with 5% H 2 SO 4 Soak in the solution for 30 minutes to remove surface oxides, and finally rinse with water until the pH is 7.0;
[0051] Step 4: Grinding with a mill to obtain a part of open-hearth slag particles with a particle size of less than 1mm, which is used as aggregate in flexible facing bricks; a part is obtained as a specifi...
Embodiment 2
[0065] In this example, converter slag is used as waste slag, and the modified converter slag needs to be obtained through the following pretreatment steps:
[0066] Step 1: Select the converter slag with an aging time of 5 months, and crush it with an impact crusher or an autogenous mill to obtain fragments with a particle size of less than 5mm;
[0067] Step 2: Use magnetic separation to remove some of the metal iron and RO phase slag with high FeO content to obtain converter slag with suitable particle size and less impurities;
[0068] Step 3: Soak converter slag in 10% NaOH solution and heat it for 7 minutes to remove surface oil stains, and then wash with 5% H 2 SO 4 Soak in the solution for 30 minutes to remove surface oxides, and finally rinse with water until the pH is 7.0;
[0069] Step 4: Grinding with a mill to obtain a part of converter slag particles with a particle size of less than 1 mm, which is used as aggregate in flexible facing bricks; a part of which is...
Embodiment 3
[0083] In this example, electric furnace slag is used as the raw material for modified electric furnace slag, which needs to be obtained through the following pretreatment steps:
[0084] Step 1: Select the electric furnace slag with an aging time of 5 months, and crush it with an impact crusher or an autogenous mill to obtain fragments with a particle size of less than 5mm;
[0085] Step 2: Use magnetic separation to remove some of the metal iron and RO phase slag with high FeO content to obtain converter slag with suitable particle size and less impurities;
[0086] Step 3: Soak the electric furnace slag in 10% NaOH solution and heat it for 7 minutes to remove surface oil stains, and then use 5% H 2 SO 4 Soak in the solution for 30 minutes to remove surface oxides, and finally rinse with water until the pH is 7.0;
[0087] Step 4: Grinding with a mill to obtain a part of electric furnace slag particles with a particle size of less than 1 mm, which is used as aggregate in f...
