Abstract
This specification refers to anshan Steel’s 1780 strip line design for the production of hot rolling strip steel factory 420 million tons. Typical products for 16MnR, products for mm thickness and width for 1520mm. The design manual includes three parts: introduction, text and topic .The first part is introduction, introduces the development status of strip and whole design should complete content. The second part (from chapter 2 text to chapter 9) is the text. The body of the whole design of the overall program description, including product and production plan formulation, metal balance and process, production equipment, process parameter calculation, rolling force. The third part of the design for the projects section, introduced the characteristics and performance requireents of GaoTieChong rail . 糠硫醇It also induces the heat treatment, heat treatment methods of function of classification, the advantages , disadvantages of various methods, the existing problems, and what the heavy rail heat treatment technology development direction. In addition, draw a workshop layout. The whole design linkes theory and practice together. It also designs the advanced technology and economic benefit of strip line.
