角钢广泛用于机械制造、建筑及其它国民经济领域,是消耗量较多的型材之一。如何降低成本对产品经济效益与社会效益有着极其重要的意义,而成材率又是轧钢生产的主要技术经济指标,因此,本文着重研讨角钢轧制提高成材率的途径。 Angle is widely used in machinery manufacturing, construction and other areas of national economy, is one of the more expensive profiles. How to reduce the cost of the product economic and social benefits is extremely important, and the finished product rate is the main technical and economic indicators of the rolling production, therefore, this article focuses on the angle rolling to improve the yield of the way.
