Three symmetrically perforated tubes were arranged in the circular cooler trolley as auxiliary cooling inlet to improve the cooling performance of the sintered body during the production process.Fluent15.0 has been used to simulate the process; the study shows that the perforated tube structure trolley has changed the temperature field within the sintering area, thereby improving the sintering area of the cooling effect and uniformity,also greatly reducingthe cooling time.Compared with the traditional trolley,the best structure of the porous tubetrolley has reduced 41% coolingtime and increased 50% waste heat recovery.
