2、原则，主要体现在：加热炉为步进梁式加热炉；进出料采用侧 进侧出；轧机采用高速无扭线材轧机；采用控制冷却技术，且轧后通过水冷箱和一套斯 太尔摩冷却运输系统。 关键词：线材，轧机，坯料，加热炉 共 2 页 第 2 页 装 订 线 New annual output of 710,000 tons to tell the wire mill Abstract Iron and steel is now the important resources of the construction of social economy, and the wire is an important part of

3、one. This design aims to build an annual output of 710000 tons of high yield of hot rolled wire rod plant. Common low carbon steel mainly introduced in this article, brief introduction of wire rod production planning process: product specifications, material selection, the selection of heating furna

4、ce, rolling mill roller selection and check, selection of cooling way and so on. This design uses the continuous casting billet, can reduce the metal cutting loss, and because of the continuous casting blank structure structure better, improve product quality; at the same time, through the use of co

5、ntinuous casting billet hot delivery and hot charging process, by reducing the burning loss, energy consumption and reduce rolling gap time to improve productivity. The design and production of high yield for the principle, mainly reflected in: the heating furnace for walking beam heating furnace; feeding the side inlet side; mill adopts high speed non-twist wire rod mill; controlled cooling technology after rolling, and through the water tank and a set of Stelmor cooling transportation system.
