Embodiment 1
[0027] See figure 1 , a method for processing sintered flue gas desulfurization slag, comprising:
[0028] Select raw materials, and use weighing equipment to select appropriate amounts of sintering desulfurization slag, steelmaking LT ash, steelmaking OG mud and converter secondary ash according to the proportion. Each raw material has a different chemical composition, specifically;
[0029]
[0030] The selected raw materials are put into the silo with the feeding port through the feeding machine respectively. There is a weight valve at the bottom of the feeding port. The weight valve opens the feeding port according to the proportion, and the raw materials fall into the conveyor belt according to the proportion; The selected sintering desulfurization slag, steelmaking LT ash, steelmaking OG mud and converter secondary ash are sent to the mixer with transportation equipment to fully mix the finished product. The mixing time of various raw materials in the mixer is 2 to 3 ...
Embodiment 2
[0033] See figure 2 , a test method for using sintered flue gas desulfurization slag as raw material for correcting cement iron quality;
[0034] Step 1: Detect and analyze the chemical composition of sintering flue gas desulfurization slag and steelmaking LT ash, steelmaking OG mud and converter secondary ash produced in the process of iron and steel smelting;
[0035] Step 2: drying steelmaking OG mud and sintering flue gas desulfurization slag;
[0036] Step 3: Weigh the following raw materials: 100kg of sintering flue gas desulfurization slag, 100kg of steelmaking LT ash, 200kg of steelmaking OG mud, and 50kg of converter secondary ash;
[0037] Step 4: Add the above four materials and a certain proportion of water into a small powerful mixer and mix;
[0038] Step 5: Conduct component analysis and leaching toxicity test on the mixture;
[0039] Step 6: After testing, Fe in the mixture 2 o 3 The content is 63.24%, SO 3 The content is 1.40%, and the moisture content ...
Embodiment 3
[0042] See image 3 , a method for using sintered flue gas desulfurization slag as raw material for correcting iron quality of cement;
[0043] Step 1: drying steelmaking OG mud and sintering flue gas desulfurization slag through a hot blast stove;
[0044] Step 2: Pour the sintering flue gas desulfurization slag and steelmaking LT ash, steelmaking OG mud and converter secondary ash produced in the process of iron and steel smelting into four feed bins with feeding ports;
[0045]Step 3: Controlled by the weighing belt, feed materials according to the following mass percentages: sintering flue gas desulfurization slag 20-25%, steelmaking LT ash 20-25%, steelmaking OG mud 40-45%, converter secondary ash 10% ~15%;
[0046] Step 4: Add various raw materials into the plow mixer mixer in turn for full mixing, and add a certain proportion of water during the mixing process;
[0047] Step 5: Transport the mixed material to the finished product silo through the belt;
[0048] Step...
