Construction process for building hot-rolled no-head strip steel production line

Abstract

The invention provides a construction process for building a hot-rolled no-head strip steel production line. The construction process is characterized in that firstly, construction is divided into three construction process zones of a continuous casting continuous rolling zone, a finished product transportation zone and a grinding roller chamber so that construction technology processes of the construction zones can be determined according to the construction process zones; secondly, construction zone section processes of the construction process zones are refined according to production process zone sections, wherein the continuous casting continuous rolling zone construction process zone comprises five construction sections of a continuous casting section, a rough rolling section, a finish rolling section, a layer cooling section and a winding section, the finished product transportation zone construction process zone comprises two construction sections of a transportation chain anda finished product storage, the grinding roller chamber construction process zone comprises three construction sections of a roller changing zone, a grinding roller zone and a roller assembly zone, and the refined construction section technological process is determined according the above arrangement; and finally, the construction section technological process is further refined into a factory foundation, a equipment foundation, an overground structure, electromechanical installation, debugging and other construction phases according to majors and parts on the basis of the construction section refinement, and the construction technological process of each construction stage is determined.

Description

technical field [0001] The invention relates to the construction field of a rolling line, in particular to a construction technique for the construction of a hot-rolled endless strip steel production line. Background technique [0002] With the continuous progress of rolling technology in the iron and steel industry, the hot-rolled endless strip continuous casting and rolling process technology has emerged as the times require. Different from other technologies, the continuous casting and direct rolling mill of the hot-rolled endless strip steel production line of this technology has a more compact equipment layout, narrow construction site, and tight connection requirements of each construction process; the main process equipment foundation and electrical The room foundations are connected to each other, and they are all box-shaped underground structures with deep foundations. The depth of the pit is wide, and the height of the base varies greatly; the installation of the p...

Different from other technologies, the continuous casting and direct rolling mill of the hot-rolled endless strip steel production line of this technology has a more compact equipment layout, narrow construction site, and tight connection requirements of each construction process; the main process equipment foundation and electrical equipment of continuous casting and rolling The room foundations are connected to each other, and they are all box-shaped underground structures with deep foundations. The depth of the pit is wide, and the height of the base varies greatly; the installation of the plant structure is large and heavy, and the hoisting station is difficult; Space, its construction requires a construction process with compact construction process, close process connection, smooth construction organization, coordinated and orderly construction, and a construction process that adapts to changes in its process and production lines.
