年产300万吨1700多品种热带连轧车间设计论文
摘 要
本设计为年产300万吨的1700多品种板带生产车间设计。本着多品种,多规格的原则制定了产品大纲,其中包括汽车大梁钢、船板钢、管线钢,汽车板用钢等,并以其为出发点,尽量从工艺上使产品做到高质量、高附加值。根据产品规格和设计要求,确定轧机各主要部件的尺寸以及一些必要的工艺参数。本设计经过仔细比较,并结合现场使用情况,选用了3架CVC轧机放在精轧机组的前段,这对产品的板形控制起到了关键作用。对典型产品压下规程的设计包括压下量的分配、速度制度的确定、温度制度的确定以及力能参数的计算等等各方面参数的选定。再有就是校核轧辊与选择电机等问题,此外,本设计还对车间内的各种消耗和厚度控制等做了简要介绍。

ABSTRACT
This paper design for the work place which yearly produces 3 million tons various straps production.. To the principle of more varieties and more specifications we develop a product program including automobile big joist steel, ship plate steel, pipe line steel ,car plate steel and so on and taking it as the starting point make the products high grade and the high attachment value as far as possibl. According to product specifications and design requirements we identify the major components of the mill size and the necessary parameters.After careful comparison, combining with the field use situation we select three CVC mills on the first part of the finish rolling , which play a key role in the plate shape control of the product. The Drafting Schedule Design of the typical product is also includes reduction distribution, the speed system, the system of determining the temperature,calculating of the power parameters and parameters selected. Checking roll and choice electrical are the key problems to normal production.In order to work smoothly, do not allow equipment full-load or overload of work for a long tinme. In addition, this design also made the brief introduction to each kind of consumption in workshop and thickness control.
Keywords: multiple products; two separate reversible rolling mills; CVC plate shape control
