Products application
Injection is a kind of technical application, which is an effective choice to improve the technical application of blast furnace in ironmaking. Blast furnace injection replaces coke and reduces the standard of coke in blast furnace ironmaking. Reducing the standard of coke can make coke ovens produce less coke. Less production of coke or less construction of coke ovens can reduce pollution sources to the natural environment. To reduce the shortage of main coking coal in China and increase the energy used in casting iron system to construct coking coal blending, it is usually necessary to use more than 50% of main coking coal to achieve the standard of coking carbon quality level in blast furnace ironmaking. There are many kinds of coal injection pulverized coal, can not use the main coking coal. This can reduce the shortage of domestic coking coal, but also can reduce the cost of purchasing coal cast iron system.
