Economic benefits of using slag accretion agents
After the slag conglomeration agent is added, the original vanadium slag loss is reduced to below 2 percent from 5 percent, and 2 percent is taken as a calculation basis for calculation:
the vanadium slag is produced by 20 ten thousand tons every year.
Then: 20 x (5-2)% =0.6 (ten thousand tons)
The price of the vanadium slag is calculated by ten thousand yuan
0.6 × 10000=6000 (ten thousand yuan)
After the slag conglomeration agent is added, the oxidability of the vanadium slag is greatly reduced, so that the degree of the vanadium slag corroding the furnace lining of the vanadium extraction converter is greatly reduced, and the service life of the furnace lining of the vanadium extraction converter can be prolonged.
The generated benefits are as follows:
after the slag conglomeration agent is added, the V2O3 grade of the vanadium slag can be improved by (1-1.5)% (the data is from a steel-climbing converter experiment), so that the quality of the vanadium slag is improved, and the corresponding cost is reduced for further purifying the V2O 3.
The addition cost of the slag conglomeration agent is 1.5-2 Kg per ton of steel, the price of the slag conglomeration agent is calculated by 3000 yuan/ton, and the cost is calculated according to 600 ten thousand tons of molten iron produced per year.
Then: 2 x 3=6 (yuan)/ton iron
600 × 6=3600 (ten thousand yuan)/year
6000-.
After vanadium slag enters a steelmaking process, because the vanadium slag belongs to meta-acid slag, the consumption of lime is required to be increased in the steelmaking process to adjust the alkalinity, so that the steelmaking cost is increased, sometimes, after the vanadium slag enters the steelmaking process in a large amount, the control is not good in the steelmaking process, the large spraying of a steelmaking converter is very easy to cause larger economic loss to steelmaking.
After the converter vanadium extraction blowing is finished, the slag conglomeration agent is added into the converter and is directly contacted with the vanadium slag to react, the reaction is very quick in a high-temperature state, the reaction is carried out for 4-5 minutes in the process of semi-steel tapping, and the effect of vanadium slag polymerization can be completely achieved
After the slag conglomeration agent is added, in the process of discharging semisteel, the semisteel tank is not overturned, so that the temperature loss caused by overturning in the semisteel discharging process is reduced, meanwhile, the problem that the semisteel overflows from the tank due to overturning of the semisteel, equipment facilities are burnt out is avoided, the occurrence of safety accidents of multiple persons is avoided, and after the overturning of the semisteel is inhibited, the environment-friendly problem that smoke dust overflows due to overturning of the semisteel is reduced.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
