Question:

The reaction of the blast furnace ironmaking is the reduction reaction: the coke produces CO in the furnace,

The reaction of the blast furnace ironmaking is the reduction reaction: the coke produces CO in the furnace,

Answer:

Please see standard: metallurgical coke GB/T1996-2003, all clear
Coke strength index is divided into cold strength index and thermal strength indexCold strength index: M40 M25 M10
Thermal strength index: CSR CRIM40 M25 is the bigger the better, the smaller the better M10CSR the bigger the better the smaller the better CRISpecific standards to see the specific requirements of steel mills
Coke index:The mechanical strength of the mechanical strength of ash sulfur%% volatile(crush strength M40) (abrasion strength M10)No greater than 12 is not greater than 0.6 not less than 80 not greater than 8 not greater than 1.9Two level 12.01-13.50 0.61-0.80 not less than 76 not greater than 9 not greater than 1.9Three level 13.51-15.00 0.81-1.00 not less than 72 not greater than 10 not greater than 1.9
