Embodiment 1
[0021] A. The iron-making dry sludge particles are ball milled in a ball mill, washed and soaked after being taken out (the purpose of washing and soaking is to desorb impurities), dried in an oven at 120°C, and then passed through a 60-mesh sieve to take dry and fine iron-making sludge Mud particles for spare;
[0022] B. Put the shale in an oven to dry at 120°C, crush the dried shale in a mortar, pass through a 60-mesh sieve, and take the dried fine shale for later use;
[0023] C, the dry fine iron-smelting sludge particles in step A, the dry fine shale in step B, charcoal powder and Fe 3 o 4 According to the percentage by weight of 50%:20%:20%:10%, mix and stir evenly, extrude into raw material ball;
[0024] D. Bake the raw meal balls in step C at 120°C in an oven for 24 hours;
[0025] E. Put the raw material balls dried in step D in a high-temperature furnace from room temperature at 120°C / h to 300°C, heat for 2 hours, then rise at 60°C / h to 550°C, activate for 20 mi...
