II. Functional Applications:
1. Lubricates the agglomeration production blend to ensure uniform mixing, thereby enhancing the stability and yield of the formed balls.
2. Improves the heat transfer conditions within the vertical furnace and in the pellets, accelerating sintering speed, shortening processing time, and significantly enhancing production efficiency. 3. Lowers the melting temperature of the blended material, improves ignition conditions, and increases the yield of finished products.
4. The halides and rare earth elements in this product help inhibit the natural disintegration of pelletized ore, facilitating storage and transportation.
5. Due to the exothermic energy-saving effect of the reaction, the consumption of gas is reduced during production, allowing for complete combustion of various substances, thereby decreasing the content of harmful gases in the exhaust and reducing environmental pollution.
6. The flame-retarding effect enables most reactions to be achieved quickly, leading to an earlier sintering endpoint, an increased vertical furnace utilization coefficient, a subsequent reduction in gas consumption, and a corresponding decrease in other fixed costs of the production process.
7. Enhances the vertical furnace utilization coefficient and improves the sinter compressive strength, yielding significant economic and social benefits.
III. Laboratory Test Results
The experiment is divided into different stages: the baseline and the test period. We take 50kg of mixed iron concentrate, calculate the addition amount based on the binder ratio, mix it with the binder manually, and stack the material uniformly three times. Then, ball formation is conducted on a balling disc with a diameter of 1000mm, a rim height of 90mm, an inclination angle of 45°, a rotation speed of 28r/min, and a continuous ball formation time of 100 minutes, with 15 minutes for the tightly packed green balls.
