| Abstract: | An experiment and research on cold briquetting coke was conducted with anthracite coal blended with lean coal and fine coking coal and with residuum of modified coal tar oil as the binder.A research discussion was made on the briquetting pressure,ratio of anthracite coal,lean coal and coke powder,quantity of residuum of modified coal tar oil,coal particle size and other main influenced factors.The paper set up the optimized technique conditions.The experiment results showed that anthracite coal blended with lean coal and coke powder could produce excellent second class foundry coke. |
