一、中小扁钢的生产特点及现状扁钢以它不同厚度和宽度灵活组合的特点,可以满足各行业对它提出的矩形断面的形状要求。国家标准中规定了厚度3～20mm,宽度10～100mm的常用中小扁钢的规格多达300余种。可以说扁钢是型钢生产中规格最多的一种轧制品种。因此扁钢被广泛地应用于国民经济的各个部门。这种生产上的灵活性和应用上的广泛性,决定了扁钢的生产特点是规格繁多且批量不大,尤其是中小型扁钢的生产更是如此。目前,扁钢的主要生产方式有两种:对
First, the production characteristics and status of small and medium flat steel Flat with its different thickness and width of the flexible combination of features to meet the various sectors of its proposed rectangular cross-section of the shape requirements. National standards in the provisions of the thickness of 3 ~ 20mm, width 10 ~ 100mm commonly used specifications of small flat as many as 300 species. It can be said that flat steel is the most widely used steel in the production of a rolled product. Therefore, flat steel is widely used in various sectors of the national economy. This kind of production flexibility and application of extensive, determines the production of flat steel is characterized by large quantities and small quantities, especially small and medium-sized flat steel production is even more so. At present, there are two main types of flat steel production: right
