摘要
Blast furnace coke containing low grade coal in a high blending ratio is manufactured by a method which comprises blending not less than 60% of a blended coal having an adjusted total moisture content of not more than 4% with not more than 40% of briquettes and carbonizing the resultant mixture.PPThe blended coal consists essentially of not less than 80% of coking coal and not more than 20% of low grade coal. When coking coal of a kind which has its coking property segregated according to its grain size distribution is pulverized and classified by sifting and the portion of fine particles is used as mixed with the coking coal, the blending ratio of the low grade coal in the blended coal can be increased to up to 35%. The briquettes consist essentially of not less than 10% of coking coal and not more than 90% of low grade coal.
