[0002] The thermal reactivity of metallurgical coke is an important quality index of coke used in blast furnaces. With the enlargement of smelting blast furnaces, the accuracy of the thermal properties of metallurgical coke plays a vital role in the furnace conditions, but the existing thermal reactivity of metallurgical coke There are differences in the uniformity of particle size and the size of the size of the experimental samples, which lead to inaccurate experimental results. Therefore, we propose a coke thermal reactive sample preparation device
