Problems solved by technology

According to the existing practice, stop production first and dismantle the concrete structure of the existing underground space of the rolling mill where the new rolling mill needs to be added, then erect a temporary foundation on the removed space, and install the new rolling mill through the temporary foundation, Removing the above-mentioned installation process of the temporary foundation can neither guarantee the construction requirement that the existing rolling line cannot stop production, but also during the installation process, due to the need to erect the temporary foundation, it will affect the construction period, and at the same time, the temporary foundation will be built first and then dismantled. , and invisibly increased the installation cost a lot, let alone gaining opportunities in the current fierce market competition

Embodiment Construction

[0015] Such as figure 1 , figure 2 Shown is an on-line installation method of an existing rolling mill with low construction cost, high efficiency and convenient installation and operation provided by the present invention. The online installation method includes the following steps

[0016] 1) Remove the concrete structure in the underground space, and use the dust-free wire saw cutting method to remove the complex underground space concrete structure on the existing rolling line that needs to be added to the rolling mill;

[0017] 2) To construct the load-bearing structure, first place the steel bars of the load-bearing structure at the position of the roll changing device on the existing rolling line that needs to be added to the new rolling mill removed in step 1), implant the steel bars of the load-bearing structure by chemical planting and bind them into shape, and then Then support the pouring formwork on the outer side of the bound and formed steel bar, and then pou...

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 ...
