The researchers studied how coke changes in blast furnaces by examining samples from different furnaces. They found that coke properties change significantly below a certain level in the furnace. This change is caused by a reaction that weakens the coke's strength and creates fine particles. The most noticeable changes happen near the race-way of the blast furnace.
