摘 要

板带钢是钢铁产品的主要品种之一，广泛应用于工业，农业，交通运输和建筑业。宽带钢在我国国民经济中的发展中需求量很大。世界各国近年来都在注重研制和使用连铸连轧等新技术和新设备来生产板带钢。

本设计为年产180万吨1780热轧带钢车间设计，典型产品厚度为5.0mm。为了满足高质量和高性能板材要求，本次设计结合唐钢1700mm、宁钢1780mm、鞍钢1780mm热轧车间设计了年产180万吨的1780mm常规热轧车间。设计采用两架四辊可逆粗轧机，轧制六道次，精轧机选用六架非可逆轧机轧制六道次，通过采用CVC轧机、PC轧机和厚度自动控制(AGC)等技术相结合来控制板型和厚度，在精轧前采用无芯轴隔热屏热卷箱。

在此设计中详细地介绍了原料的选择、生产工艺的制定、典型产品工艺计算、主要设备和辅助设备的选择等一系列过程。按照要求计算了轧制力，轧制力矩，电机功率等问题，且对轧机进行了校核，并且设计了凸度，挠度以及年产量等问题。

ABSTRACT

Plate strip is one of the main varieties of steel products, widely used in industry, agriculture, transportation and construction. Wide strip in the development of our national economy in great demand. In recent years, countries in the world are paying attention to the development and use of continuous casting and rolling, and other new technologies and new equipment to produce steel strip.

The 1780 is designed to produce 1.8 million tons of hot rolled strip plant design, a typical product thickness 5.0mm. To meet the requirements of high quality and high performance boards, this design combines the Tangshan Iron and Steel 1700mm, Ning steel 1780mm, Anshan Iron and Steel 1780mm hot rolling workshop designed annual output of 1.8 million tons of 1780mm conventional hot rolling workshop. Design uses two four-high reversing roughing mill, rolling six times, finishing mill selected six non-reversible rolling mill six times, through the use of CVC mill, PC mill and thickness control (AGC) to control panels and other technology-based combination and thickness, in the no-mandrel before finishing the heat shield coil box.

In this design details on the selection of raw materials, production process development, process calculation typical products, the main equipment and auxiliary equipment such as a process of selection. In accordance with the requirements in the rolling force, rolling torque, motor power and other issues, and conducted a check on the mill, and the design of the crown, deflection, and output issues.

Key words: hot rolling; plate strip; CVC mill; rolling schedule
