1985年以来,我厂在用60mm方坯轧制φ12mm圆钢中一直采用辊切分轧制新工艺。根据三年来生产实践,就轧辊切分技术孔型设计方面的理论问题谈谈体会。 1.轧辊切分方法的选择热切分轧制方法不一,它可以根据轧机的型式、产品形状及工艺特点进行选择。我们选择了轧辊切分法,这种切分法有两种型式:一是靠轧辊重合切分,如同圆盘剪切型 Since 1985, our factory has been using roll cutting rolling new technology in 60mm billet rolling φ12mm round bar. According to three years of production practice, on the roll pass technology theory design talk about the experience. 1. The choice of roll cutting method Heat slicing rolling method varies, it can be based on the type of mill, product shape and process characteristics to choose from. We chose the roll segmentation method, this segmentation method has two types: First, by the roller coincidence, as the disc shear
