Abstract:The article calculates in progress by thermoplastic finite element method. This finite element is a kind of elasticplastic finite element in three dimensions. On the basis of this method,we can revise in progress for deformed area ,according to produce drawingeffect during rolling sheets. By this method, we also can calculate accurately rolling pressure, rolling square, pressing flat of rolls, flatness and convex of rolls, so that improving quality of flatness, decreasing thickness difference from the same sheet, increasing adjusting leeway of rolls and increasing wearresisting result of rolls.
