Some knowledge questions about coke ovens

Thread Content

1. Coke in a blast furnace serves three functions: (heat source), (reducing agent), and (loosening the structure); among these, the role of (loosening the structure) is irreplaceable. 2. The cold strength of coke is related to its (pore size) and (distribution), whereas its high-temperature strength is closely associated with the (wall thickness of the pores). 3. The void structure of coke is usually represented by parameters such as its crackness, porosity, average pore diameter, and specific surface area. 4. The (pore pocket structure) of coke affects the wear resistance index M10 value, while the (crackness) of coke influences the crush resistance index M25 value. 5. The factors affecting coke reactivity include (the properties of the raw coal) and (the coking process). When the temperature during the measurement of coke reactivity is below 1100 degrees, the overall reaction rate seems to be controlled by the (pore diffusion rate). 6. The liquid in the suction pipe flows toward the chemical production plant due to (slope) and (liquid level difference). 7. Basic requirements for coal loading: (Fill completely, compact, and level.) On average), the basic requirements for pushing coke are: (on time, steady pushing).
