Renovation Method of Adding Rolling Mill to Existing Rolling Line

Abstract

The invention discloses a reconstruction method for adding a rolling mill on an existing rolling line. By the aid of the reconstruction method, the downtime can be shortened. The reconstruction method comprises that an old roller way in a new rolling mill area is removed, and then a temporary roller way is arranged at the position; a rolling mill foundation is constructed under the temporary roller way; and a push foundation and a push railway which is located on the push foundation are arranged in a construction area outside the rolling line, the push railway extends to the rolling mill foundation, the rolling mill is assembled on the push railway, then the rolling mill is pushed onto the rolling mill foundation by a push device, a reinforcing foundation of a rolling mill rack is constructed and fixed after the rolling mill is in place, then the push foundation serves as a foundation construction roller changing device foundation, and finally installation and piping of a roller changing device are finished. By the aid of the method, the downtime caused by reconstruction can be shortened greatly, and the method is significant in economic benefit and social benefit and is mainly applied to reconstruction of the existing rolling line by adding the rolling mill.

Description

technical field [0001] The invention relates to a rolling line transformation method, in particular to a rolling mill transformation method for an existing rolling line. Background technique [0002] At present, for the rolling production line that has been in production for many years, it is usually required to shorten the stoppage time as much as possible to reduce the production loss of the production plant when the transformation of adding rolling mill units is carried out. [0003] The conventional way to improve the rolling production line by increasing the rolling mill unit is to completely stop production and improve, and shorten the working hours required for the improvement as much as possible to shorten the stoppage time. The process flow is: stop production→removal of part of the laminar flow roller table→remove the foundation of the roller table to the top surface of the basement floor→foundation construction of the rolling mill and supporting equipment→installa...
