Functional Features:

The device is based onGB/T 4000-2008The "Test Method for Reactivity and Post Reaction Strength of Coke" is designed and manufactured for the determination of reactivity and post reaction strength of coke used in blast furnace ironmaking.

Adopting a precision temperature control device with high control accuracy, easy to use and maintain, and equipped with safety measures such as automatic power-off and thermocouple protection for overheating.

The high-temperature reaction furnace is controlled by a computer to heat up at a certain rate and control the temperature according to a given temperature. Various changes in the coke during the reaction process can be captured on the computer display screen, and the entire reaction process can be correctly recognized. At the same time, multiple experimental process data can be stored and equipped with automatic rise and fall, automatic combustion of exhaust gas, and automatic discharge devices, achieving automation of the experimental process.
