Magnesium reduction is helpful to improve the grade of sinter, to develop high quality calcium ferrite, and to light burn magnesium powder to improve the reducibility of sinter. The TFE content of sinter can be increased by more than 0.3% when MgO content is reduced by 0.5%; under the background of the deterioration of imported ore powder, magnesium adjustment shows the value of actively maintaining sinter grade. The improvement of sinter grade is helpful to form more high-quality Ca2 + ferrite, which is beneficial to the improvement of Sinter Index and reducibility.
Reducing magnesium is helpful to reduce heat consumption of flux and increase effective heat of sintering. The decomposition heat consumption of magnesium containing flux in the sintering process, and reducing the ratio of magnesium containing flux will help to save energy and improve the quality of sinter. The results show that the MgO content of sinter is reduced by 0.5%, the magnesium flux consumption is reduced by 14kg / T sinter, and the decomposition heat consumption is reduced by about 1%, which is equivalent to that the effective heat of sintering process is increased by 1% under the condition of a certain sintering heat loss, which is conducive to the improvement of sinter particle size composition.

Magnesium reduction can improve the fluidity of sintering liquid phase and enhance the sintering bonding effect. The basic sintering characteristics and high temperature confocal equipment tests show that the liquid flow index increases from 0.7 to 1.9 when the MgO content of sintering mixture decreases from 2.3% to 0.3%; compared with the scheme containing MgO, the scheme without MgO has higher liquid flow velocity. The improvement of the fluidity of sintering liquid phase enhances the bonding effect, which is conducive to the improvement of sinter particle size composition.
On the basis of ensuring the stability of blast furnace slag system, the drop property of comprehensive burden is improved by sintering magnesium reduction and pellet magnesium extraction. The droplet performance test shows that after the comprehensive charge structure changes from sinter 1.9% MgO + pellet 0.7% MgO to sinter 1.5% MgO + pellet 1.7% MgO, the droplet range decreases from 64 ℃ to 59 ℃, the large pressure difference decreases from 1910 PA to 1590 PA, and the s characteristic value of the comprehensive charge decreases from 122.2 kPa · ℃ to 93.8 kPa · ℃. On the road of sustainable development, Dashiqiao City puts the sustainable development of light burned magnesia powder in an important position, makes full use of its own advantages, adheres to the guidance of scientific and technological innovation, scientifically formulates development plans, encourages technological innovation, improves guidance policies, implements major projects, optimizes the development environment, and promotes the progress and development of industrial technology, so as to realize the transformation from resource advantage to economic advantage The change of potential. In the evaluation of the Approved National Sustainable Development Experimental Zone, the development of magnesium industry accounts for more than 60% of the total.
It is well-known for its rich magnesium resources. It is one of the "four major magnesium mines" in the world and enjoys international reputation. How to transform this unique resource advantage into economic advantage is the main direction for Dashiqiao City to create a National Sustainable Development Experimental Zone. Therefore, the sustainable development strategy of magnesium industry based on resource advantages was first implemented.
