Embodiment Construction
[0015] The specific embodiment of the present invention is further described below in conjunction with accompanying drawing:
[0016] A method for preparing a coke sample is characterized in that it is carried out in the order of first pelletizing and then coking, and the specific operation steps are as follows:
[0017] 1) Put the weighed coal powder into the mold of the coke sample forming device, press the coal powder into a ball with a pressure of 20N-30N under normal temperature conditions, and get a diameter of Φ25 after demoulding. –0.1 mm, volume 8.18cm 3 , the density is 1.1g / cm 3 ~1.2g / cm 3 coal powder balls;
[0018] 2) The pulverized coal balls are placed in the coke oven of the smelting experiment. Under the condition of isolating the air and the temperature is 950 ° C ~ 1050 ° C, after 8 ~ 9 hours for high temperature dry distillation, the formed body has a diameter of Φ25 –0.1 The regular coke balls of mm are used as test samples for coke reactivity and post...
