the observed effects of temperature on wear of roll materials via oxide influence may be explained as follows: (i) the oxides formed in the range 400-600 are fez03 and fe304 and increase abrasive wear; (ii) in contrast, within the range 600-900 , the progressive formation of wustite increases the lubricating effect of the scale and effectively decreases roll wear; (iii) at temperatures above 900 , the formation of magnetite and haematite leads again to an increase in abrasive wear.wear mill, stockport,wear mill (also known as weir mill) was an integrated cotton works on the cheadle heath bank of the river mersey in stockport, greater manchester, in england. it was started around 1790 and added to, particularly in 1831 and 1884. in 1840, the stockport viaduct was built over the river and over wear mill.
