Based on the study of the chemical principle of the adhesive effect, the pellet organic binder molecules were preliminarily designed using MO theory and gene electronegativity calculation. A new type of pellet binder was synthesized based on a preliminary designed molecular model. In the laboratory using the new binder for pellet preparation and roasting test, the ball had a compressive strength of 21.8N /. Falling 6.67 times / 0.5m, the ball compression 323N / a. 16.18 times / m drop, burst temperature of raw balls 820 ℃, the compressive strength of roasting pellets is more than 2000N / month technical indicators.
