新建年产212万吨宽厚板车间设计 摘要 宽厚板是国民经济发展所依赖的重要钢铁材料之一，是工业化进程和发展过程中不可缺少的钢铁品种。世界钢铁工业的发展历程表明，宽厚板的生产水平及材料所具有的水平也是国家钢铁材料水平的一个重要标志。 本设计是年产量为212万吨的宽厚板生产车间，其典型产品为GB3531-09MnNiDR，代表产品规格为13×4000×9000mm。PC轧机， 关键词：宽厚板；车间设计；压下规程；低压容器板 The New design of a wide -thick plate workshop with annual capacity of 2.12 million ton Abstract： Wide-thick plate is one of the important steel materials that the national economic development depends on. It is an indispensable steel variety in the process of industrialization and development. The development course of the world steel industry shows that the level of production and material of wide-thick plate is also an important symbol of the level of the national steel industry. The design is the annual output of 2.12 million tons of heavy plate production workshop, the typical product for the GB3531-09MnNiDR, on behalf of the product specifications for 13x 4000x9000mm. In the design process of the whole workshop, the production technology and development, the gap between domestic and international production technology and the new technology of core rolling are introduced. In this design, the rolling need to longitudinal rolling, but also need to transfer steel in the rolling gap. Rolling equipment includes: two walking beam heating furnace, tumbling Machine, high pressure water descaling unit, a four-high reversing mill, PC rolling mill, and various ancillary equipment. In the design, based on a set of annual output, combined with the market prospect of the product, the product scheme was designed with reasonable design method and technical rules. Taking typical products as an example, the process flow and rolling schedule are established. The rolling system includes: systems of pressure, velocity and temperature system; rolling force calculation are carried out and the strength of the roller and the load of the motor are checked. In the design, the working time of the year is reasonable, so that the production capacity of the workshop is
