Abstract

AGUILAR-CASTRO, Yesid et al. Wear in Low Carbon Steel Due to Clean Bagasse or Bagasse Containing Silica and Sugar Cane Juice. Ing. Univ. [online]. 2011, vol.15, n.2, pp.373-384. ISSN 0123-2126.

This paper presents a study carried out to determine the effect of mineral extraneous matter and sugarcane juice on the wear of sugar cane rollers which get in contact with bagasse. A prototype based on the ASTM G-65 standard machine, whose low carbon steel is worn by sliding it against bagasse, was designed and built. Tests with and without juice in the bagasse were carried out. Additionally, the level of mineral extraneous matter was varied. Silica sized between 0.212 and 0.300 mm was used as mineral extraneous matter. Wear was measured in terms of the weight loss shown by the specimens. Scanning electron microscopy was used to analyze worn surfaces. It was found that wear is higher with juice, which causes steel to corrode. This also happens with the presence of mineral extraneous matter. The main wear mechanism observed on the worn surfaces was plastic microdeformation and micro-cutting due to the silica grains.

Keywords : Carbon stell; mechanical wear; materials - dynamic testing; silica; sugarcane juice.
