2017-7-1 The method used to determine the coke’s ability to withstand abrasive and impact forces has been codified in GOST State Standards (in terms of the strength indices M 25, M 40, and M 10). However, there is no standard method for assessing the ability of the coke to withstand crushing forces.

Ferro-coke, as a new burden of blast furnace (BF), can not only greatly reduce the energy consumption and CO2 emission, but also promote the resource utilization by using the low-quality iron ore and low-grade coal. However, the strength of ferro-coke decreased with the increasing amount of iron ore powder. In order to maintain the strength of ferro-coke while increasing the amount of iron ore ...

2021-11-24 Snorting coke involves crushing the drug into a fine powder. As users snort cocaine, the drug needs to travel from the blood vessels in the nose to the heart, which then transports the substance into the lungs to be converted into oxygen. The blood with the corrupted oxygen then returns to the heart, which is pumped to other organs.
