Detection device for thermal-state performance of coke

The invention relates to coke for an iron-making blast furnace, in particular relates to a detection device stimulating a furnace pressure environment of the blast furnace and particularly relates to the detection device for thermal-state performance of the coke. The detection device comprises an electric furnace, a reactor, a thermoelectric couple, a reactor air inlet pipe, a reactor air outlet pipe, a liquid nitrogen bottle and a liquid carbon dioxide bottle, wherein a sealed and pressure-proof upper end cover and a pressure regulating device for controlling pressure in the electric furnace are arranged on the upper end of the electric furnace; and an electric actuating mechanism and a valve form an electronic pressure regulating valve together, and the electric actuating mechanism is connected with an intelligent control instrument. According to the detection device for the thermal-state performance of the coke, as the intelligent control instrument is arranged, each electronic control assembly can be uniformly managed, so that the automatic control is achieved; the automatic control and detection can be carried out only by setting preset conditions, and the detection data is recorded, so that the working efficiency can be improved; and most importantly, the furnace pressure environment of the blast furnace can be stimulated by utilizing the detection device, the coking production can be better guided, the operation quality of the blast furnace can be better improved, and the economic benefits of enterprises are increased.
