Outline
The basic pellet with limestone and low reduction expansion rate added 75% Bayan Obo iron concentrate is researched and developed aiming at the special nature of Bayan Obo iron concentrate. It is suggested that the proportion of bentonite is 1.5%~1.8%, alkalinity is 1.15±0.05 and proportion of limestone is 3.5%~3.8% for producing basic pellet with the process of chain grate machine-rotary kiln-ring cooler of Baotou Steel as well as explored the basic pellet is with such process system as good compressive strength, mineral composition and metallurgical properties, which could provide the technical supports for producing it with chain grate machine-rotary kiln-ring cooler of Baotou Steel.
