Change in the physical and mechanical properties of coke in the process of transport from the wharf to the blast furnace skip
The most important indices of the physicomechanical properties of coke are the strength and granulometric composition. They are closely interrelated in that the strength of the lumps determines its granulometric composition and the composition is an index of the varying tendency of coke lumps to break. An investigation was undertaken to determine the changes in the coke mechanical property indices along the movement path from wharf to blast furnace. Coke specimens were collected at three points along the transport path: from the conveyors under the wharfs (one drop of 500 mm); from conveyors located after the screening out of below 40 mm size class (a total drop distance of about 4.8 meters in 3 drops); and ahead of the skip of the blast furnace after screening out the below 25 mm size class (one drop of about 850 mm). The changes in particle size, mechanical strength, structural strength, apparent density, and porosity are shown in a table for each sampling point. 7 references, 1 figure, 1 table.
