Abstract
A thermal-mechanical analysis of the behavior of the segments of the rollers of the briquetting machines is carried out due to the effect of thermal shock and efforts exerted on the part. It is intended to obtain the main causes that generate this problem, through a mechanical analysis that simulated the behavior in the presence of several thermal gradients. The purpose of the study is to reduce maintenance costs and the continuous replacement and repair of segments, as well as losses in tons of production due to the failure that are of great impact to the industry. This investigation allows us to know to what extent the operating parameters, such as material temperature, pressure, torque, speed of the rollers influence the life of the segments according to their manufacturing material, and based on these the behavior is simulated during the briquetting process.
