Abstract

The invention discloses a coke high-temperature dynamic reactivity controller, which can detect, control and display temperature signals and carbon dioxide and nitrogen flow signals simultaneously. The coke high-temperature dynamic reactivity controller comprises a signal amplification part, a filter circuit, an AD (Analog to Digital) converter, a signal chip microcomputer PIC16F877A, 0-5V signal input, 0-5V signal output, a keyboard, a display panel, a 485 communication bus and a power module. The coke high-temperature dynamic reactivity controller has the functions of temperature control, two-loop flow control and collection, and is particularly suitable for being used as a controller of a coke high-temperature reactivity furnace. The controller is good in stability and very strong in antijamming capability, and has a sensor channel fault diagnostic function; and a communication channel has very high isolation voltage which can reach 1000 volt.

Description

technical field [0001] The invention relates to a control device for a coke high-temperature reactivity furnace, in particular to a coke high-temperature dynamic reactivity controller. Background technique [0002] With the development of large-scale blast furnaces, the requirements for the quality of coke are getting higher and higher. In particular, researchers in this industry generally pay attention to the thermal properties of coke. At present, the coke national standard reactivity and post-reaction strength standards are generally used to measure the thermal properties of coke. This measurement index has a certain role and discriminative power in measuring the coke’s resistance to carbon dissolution loss in the blast furnace. In fact, the reaction conditions in the soft melting zone of the blast furnace are quite different from the experimental conditions of the current national standard reactivity index. The actual temperature of the carbon dissolution loss reaction i...
