The comparison of wear rate and lifetime of the spiral fuel briquette extrusionFrom different quenching media of hardening

Abstract

This research is the comparison of wear rate and lifetime of the spiral fuel briquette extrusion from different quenching media of hardening. The operation of project, use the charcoal fuel screw compress from carbon steel as 0.20%C by weight to pack carburizing process at 930C holding on time at 210 minutes for the carbon increasing more than 0.35%C by weight. Next, take to flame surface hardening at 860C on time 60 minutes and quenching in water, oil and air respectively. Next, take the charcoal fuel screw compress to testing on hardness, wear resistance on grinding wheel, and working charcoal fuel screw compress. The result of project, it was found that the charcoal fuel screw compress from pack carburizing and flame surface hardening, quenching in oil have quality and mechanical properties highly than other quenching medias. And it has hardness at 56 HRC, wear resistance and highly at 0.08% by weight. And the resistance to wear from the actual working conditions at the test range compressed charcoal corn cob of 2 0 0 kg at 0.3% by weight.
