MAKING METHOD OF SINTERING ORE

摘要

The present invention related to method for manufacturing anthracite high-admixture sintering iron by substituting powder coke used as heat source in sintering process for anthracite in the range of proper grading above regular mixture ratio.The present invention is characteristic of adding anthracite with 30-70 weight% to the total weight of powder coke and anthracite as heat source, and grading of said anthracite is below 8mm, grading of anthracite which is above 1mm is above 49 weight%.
