Embodiment 1
[0022] A treatment method for high-temperature high-silicon molten iron in this embodiment uses 300-ton torpedo tanks for the transportation of molten iron. Iron-containing oxides are added before molten iron. The high-temperature high-silicon molten iron is: molten iron temperature ≥ 1500 ° C, molten iron Si element mass fraction ≥ 0.6%; 100-500kg of lime, the lime particle size range is: 10-20cm, which is used to inhibit the reaction of C element and iron oxide in the molten iron to form foamy slag. The specific test conditions are shown in the table below.
[0023] Table 1 High-temperature high-silicon hot water treatment test table
[0024]
[0025] It can be seen from the experimental results that the high-temperature high-silicon molten iron treated by this technical scheme uses excess heat for heating and reducing iron-containing oxides when the torpedo tank receives the molten iron, increasing the amount of molten iron and keeping the temperature of the molten iron ...
Embodiment 2
[0027] A treatment method for high-temperature high-silicon molten iron in this embodiment has the same basic structure as in Embodiment 1. The difference and improvement are that the iron-containing oxides include sintered ore, pelletized ore, iron oxide scale, wherein sintered ore, pelletized ore The mass ratio of iron oxides in the pellets and iron oxides is ≥90%, and the added amount of the iron-containing oxides is:
[0028] M=1.43×10 -4 ×(T 1- a×△T-T 2 )×M 铁水 ;
[0029] Among them, M is the amount of iron oxide added / ton, M 铁水 is the mass of molten iron / ton, T 1 is the tapping temperature / °C, the value range of a is: 1.84~1.95, △T is the annual average temperature drop / °C during the process of transporting molten iron from the ironworks to the steelworks, where T 2 It is the target temperature / °C before entering the converter.
[0030] Wherein, the target temperature T before the converter 2 for:
[0031] T 2 =1280-((b×Si content of molten iron)-0.60%)×10 4 ×c...
