Coal briquette having superior strength for smelting reduction iron making process and briquetting method thereof

摘要

PURPOSE: A method for producing coal briquette having superior strength for Corex process is provided, which is characterized in that lime is mixed with coke breeze to remove moisture of coke breeze. Therefore drying process of coke breeze is not necessary. And molasses is added to increase strength of coal briquette. CONSTITUTION: According to the method, the coal briquette is made by the following steps: mixing 100 parts by weight of coke breeze and 1-5 parts by weight of lime; aging the mixture; adding 7-15 parts by weight of molasses, based on 100 parts by weight of coke breeze into the mixture; agitating the mixture; and (e) molding the mixture. The size of lime is less than 1mm wherein the particle size fraction less than 0.3mm occupies 0.5 of total lime. Obtained coal briquette is used to metallurgical process.
