Abstract

The invention particularly relates to a coke high-temperature performance detection device and a detection method, and belongs to the technical field of coke thermal performance detection. Two cavities are arranged on a conventional coke reactivity testing device, and two reactions of ore reduction and coke solution loss can be completed at the same time. And the loading amount of the ore is obtained through calculation according to the actual load condition of the blast furnace. The reaction gas after ore reduction is directly introduced into the coke reaction tube to participate in the reaction, so that the reaction atmosphere of coke in the blast furnace can be more accurately simulated, and the obtained coke reaction performance index better conforms to the actual state in the blast furnace.

Description

technical field [0001] The invention belongs to the technical field of coke thermal performance detection, and in particular relates to a coke high-temperature performance detection device and detection method. Background technique [0002] Coke is an indispensable raw material in the process of blast furnace ironmaking. On the one hand, it acts as a reducing agent to provide the reducing gas CO required for ore reduction; on the other hand, it acts as a support for the tens of meters of blast furnace material column. Among coke evaluation indicators, reactivity CRI and post-reaction strength CSR have received extensive attention from ironworkers. Among them, CRI corresponds to the ability to provide CO reduction gas, and CSR corresponds to CO 2 After the reaction, it still has the ability to support the blast furnace material column. [0003] At present, the thermal properties of coke are measured in accordance with "GB / T 4000-2017 Coke Reactivity and Post-reaction Strengt...
