Vanadium slag vanadium-iron alloy on behalf of the Study
Factory, Construction Bureau and other units to use, does not appear abnormal. Fifth, direct alloying of vanadium slag vanadium slag economic clever direct alloying vanadium steel, while reducing agents and slagging material alloy of vanadium with a ratio of increase, however, iron and vanadium slag vanadium price disparity, vanadium slag about 2,500 yuan / t, vanadium iron 64,000 yuan / t, therefore, the use of vanadium slag vanadium iron instead of very significant economic benefits. Table 5 shows that can reduce the cost of steel smelting 09SiVL 106.15 yuan / t, 40Si2MnV steel can reduce the cost 135.4O yuan / t. VI Conclusion 1. Instead of vanadium slag vanadium 09SiVL direct alloying of iron and steel technology is feasible 40Si2MnV, recovery and stability of vanadium oxide, with the thin end of adding vanadium slag slag and vanadium recovery rate of 83 ~ 96.2. Direct alloying with vanadium slag,[link widoczny dla zalogowanych], steel, inclusions, low magnification not so abnormal, without increasing the harmful elements in steel, the metallurgical quality of steel had no effect. 3. Vanadium steel slag directly Taijin his and other mechanical and technological properties of the steel alloy with vanadium showed no significant difference in the strength of steel only 40Si2MnV high 30 - 5 ~ MPa. 4. Vanadium-iron alloyed steel, the processing performance and performance are good, not abnormal. 5. Instead of vanadium slag vanadium iron smelting low-vanadium steel, light a significant economic effect, 09siVL steel can reduce the cost of 106. I5 element, t steel, 61991 No. 5 set smelting vanadium slag and vanadium @ ~ SiVL, 40Si21VInV vanadium steel cost comparison table arbitrage 12g52BO1 s at 10O at 500446O77209SiVL Vanadium 226530.1514 day 70 - 5Dl57 contrast -107 +127 + O. 5 +04 day at 20 with a 044-1O6.15 Citrus - 17 V milling 52.0101.

Instead of vanadium slag vanadium iron work,[link widoczny dla zalogowanych], 09SiVL trial production of steel can be expanded, 4OSi2Mnv can be put into mass production of steel, vanadium can be extended to other low-profile magic of the tests. Reference E13 of the direct use of vanadium slag vanadium steel increased ~ DpooEmbi, Kavkhapa \5.1966.1BO ~ l65. Hu. 20MnTi reinforced Study 1g85, such as Anshan Iron and Steel Division Sheng. E47 King lay spider, Zhang Kelan. 198g,[link widoczny dla zalogowanych], 1O (1) l15. Not burned magnesia chrome brick, carbon pellets passed technical appraisal of the \Application of high-carbon ferrochrome slag - not burned magnesia-chrome brick factory with the use of iron Taijin Cr. O. The successful development of waste as raw material, because without high temperature baking, a significant reduction in energy savings per ton of bricks about 2 tons of coal to produce 3,000 tons per year to save 6,000 tons of coal, worth 1.08 million yuan rub on the steel open hearth furnace and a glass factory, nodular factory units to use, proven to be a promising basic refractories. Shanghai every year 3 to 4 million tons of chromium waste emissions, environmental pollution, if the rejection of all the thorns, not only environmentally-friendly management, and can of waste into treasure, but also according to different treatment processes, production series of high profile Refractories, the social and economic benefits considerable. \Shanghai Steel's steel-making furnace dust is prepared each year about 6 million tons of rolled iron oxide scale of about 80,000 tons per year, iron grade of about 60 to 70, annual emissions of pyrite cinder total of 40 million metric tons, the double magnetic separation, the grade of up to 55, sulfur 0.25. In addition the city the focus of a large number of the plant debris, waste lime powder are used as iron raw materials. The environmental governance of waste into energy conservation led Ⅱ with comprehensive research, is a national initiative, tests showed that carbon pellets with 20 students instead of iron, on the cupola of the operation showed no ,[link widoczny dla zalogowanych], as long as the establishment of an annual lfi0 tons of pellet plant,[link widoczny dla zalogowanych], you can use the existing 740,000 tons of molten iron smelting furnace, blast furnace output is equivalent to a 1250m.
