In the paper, the differences of phosphorus content in coking coal of each region were studied based on the phosphorus content in coking coal of Baotou Steel as well as the phosphorus contents in blended coal and coke under the same production condition were tested and analyzed to obtain the data transformation relation between them. Meanwhile, the mode of occurrence of phosphorus in coal was analyzed to study the correlation between phosphorus content, ash content and sulfur content. The results showed that there were significant regional differences for coking coal of Baotou Steel as well as there was a positive correlation between phosphorus contents in blended coal and coke, which provide important support for predicting the phosphorus content of coke and controlling the phosphorus load of coke of blast furnace.
