What are the ways to improve coke M10?
There are many ways, but the key is to choose good coal
Add more coking coal or fat coal to raise the standard temperature and extend the coking time.
Reduce the volatiles in the blended coal, establish an appropriate temperature regime to ensure proper coking maturity
The lower the M10 value, the better; improving the quality of coke should involve reducing M10. To reduce M10, it is possible to increase the proportion of coking and fat coal in the coal mix, ensure an appropriate degree of coking during heating, or change the quenching method.
Increase the temperature at the center of the coke cake and extend the coking time by 1 hour
Pay attention to the coking moisture, whether it is a ramming or top-loading furnace
How much impact does the moisture content of coke during quenching have on M10 in rammed coke ovens? How can M10 be reduced through the moisture content in coked coal?
Wear resistance is closely related to the bonding index and volatile matter content of coal; it is also associated with the conditions of coking and the moisture content during quenching, but these factors are of secondary importance
Increasing the bonding index and Y value of blended coal, as well as raising the temperature at the end of coking – that is, the rapid coking method – can improve M10.
