Shaking ladle as in smelting, the main productions of green products, its principle is charged material into shaking ladle, allows shaking ladle
Horizontal circular movement is done, the wave stirred up and down is formed in shaking ladle, liquid alloy is fully contacted with clinker.
In manganese-silicon production process, because manganese and carbon can generate stable compound Mn3C, it is reduced directly and is aoxidized with carbon
What manganese obtained is not pure manganese, but the carbide Mn of manganese3C.Compare Mn because silicon and manganese can generate3Compound more stable C
MnSi, thus it is as follows using following chemical reaction occurs in shaking ladle process production, during low-carbon ferromanganese, in shaking ladle：
2Feo+Si=2Fe+SiO2
Mn3C+Si=3MnSi+C
In being produced using shaking ladle process, during low-carbon ferrochromium, the chemical reaction occurred in shaking ladle is as follows：
2FeO+Si=2Fe+Si02
2Cr2O3+ 3Si=4Cr+3SiO2
Because C and SiC density is less than the density of ferroalloy, therefore, C and SiC in liquid alloy constantly float, gathered
Collection, promote adsorption reaction and the progress of chemical reaction, reduce the phosphorus content in ferroalloy, improve beneficial to recovery rate of iron.
In recent years, shaking ladle technique is used widely during ferroalloy smelting.But in shaking ladle production process, liquid
Body vigorous exercise in the presence of inertia force and containment wall applying power, liquid level is higher than standby fluid level more than 1 times in bag, therefore,
The dischargeable capacity utilization rate of shaking ladle is relatively low.Further, since shaking ladle uses horizontal circular movement, it is dead liquid flowing to be present in shaking ladle bottom
Area, clinker can not be contacted fully with Molten Ferroalloys, hinder the progress of adsorption reaction, and production efficiency significantly declines, must not
The shaking ladle of bigger volume is not taken, to meet production requirement, so as to cause energy consumption to increase.
Therefore, develop new ferroalloy refinery practice and equipment meets country and rebuild traditional industry, adjusted with new and high technology
Product structure, energy-conservation etc. industrial policy, this project construction are very important to the development for promoting ferroalloy smelting technique,
Its economic benefit and the equal highly significant of social benefit.
