Online mounting method for mills on existing rolling lines

Abstract

The invention discloses an online mounting method for mills on existing rolling lines and belongs to the technical field of metallurgical production equipment mounting. According to the method, the construction cost is low, the efficiency is high, and mounting and operation are convenient. The method comprises dismantling online complex underground space concrete structures at positions on existing rolling lines, where mills are required to be added, through a dustless wire saw cutting method; planting reinforcement bars at positions of roll changing devices at dismantled positions, pouring bearing structures with the section in a concave structure, and mounting steel beams and push rails on the bearing structures; assembling newly added mills on the push rails, and pushing the push rails onto mill foundations.

Description

technical field

[0001] The invention relates to an on-line installation method, in particular to an on-line installation method for an existing rolling mill, and belongs to the technical field of metallurgical production equipment installation. Background technique

[0002] To add a rolling mill online to an existing rolling line, it is first necessary to dismantle the complex concrete structure in the underground space of the existing rolling line, and then re-install the new rolling mill online at the removed position, and at this time the existing The rolling production line cannot be shut down, and at the same time, the quality of steel products produced by the existing rolling line must be guaranteed, which puts forward very high requirements for the installation of new rolling mills on the existing rolling line. According to the existing practice, stop production first and dismantle the concrete structure of the existing underground space of the rolling mill where the ...
