1, meet the technical requirements of GB/T4000-2017 "Coke reactivity and post-reaction strength test method" national standard.
2, unique double furnace design, each furnace can operate independently. Each furnace can complete the test alone or double furnace at the same time.
3, each heating furnace has three independent heating area, three sections of heating area is independent temperature control, to achieve a true sense of the constant temperature area, the constant temperature area is greater than 300mm.
4, unique gas path design, the gas path of each furnace is a standby, N2, CO2 each two bottles, when a gas flow is insufficient, the automatic switch to the standby gas within 30 seconds, and alarm.
5, the use of mechanical and electrical integration design, reactor loading and unloading for the bottom mechanical transmission, after the test is automatically released, unattended.
6. Ball screw is used to upgrade the manipulator, which runs smoothly for a long time. High positioning accuracy.
7, Optional unique gas purifier, may make ordinary N2 and CO2, purified into 99.99% of the purity of the gas.
8, the test process temperature control, N2 and CO2 conversion, CO2 preheating, reactor out of the whole process is automatically completed by Germany Siemens PLC. When the coke drops to 100℃, the alarm is raised to remind the operator to carry out post-reaction strength test.
9, gas flow control using mass flow controller, not only accurate and reliable flow, display flow curve at any time, with insufficient flow alarm function.
10, the system into the test state automatically start the test ventilation system, exhaust gas burning out of the outdoor, to prevent the test personnel poisoning, to ensure indoor air circulation.
11, double system protection function to prevent the control failure of the main control system, thyristor breakdown and other accidents, resulting in overtemperature of the electric furnace, burning the reactor or insulation material.
12, touch screen display three temperature zone temperature curve, gas flow curve and other related parameters.
13, with overpressure protection function.
14, I type drum integration design, with the number of automatic control function, discharge and loading without unloading drum.
KF-8000A automatic coke reactivity tester, the device conforms to GB/T4000-2008 "coke reactivity and post-reaction strength test method", suitable for the determination of coke reactivity and reaction strength for blast furnace ironmaking coke, the use of precision temperature control device, high control accuracy, easy to use and maintenance, with over temperature automatic power off, Break protection and other safety measures.
■ Standard control process:
Room temperature ~ 1100℃, heating rate 15℃/min (adjustable); 400℃ through 0.8L/min nitrogen protection; 1050℃ preheat carbon dioxide; 1100±5℃, stable for 10min, cut off nitrogen, pass 5L carbon dioxide, reaction for 2h, electric furnace stop heating; The reactor is lowered into the oven, carbon dioxide is cut off, and 2L nitrogen is passed for protection. When the coke drops to 100℃, the test is over. All the above processes are automatically controlled by Siemens PLC.
