Embodiment Construction

[0085] The 4300 rolling mill is the most advanced reversing rolling mill at home and abroad. Due to its high installation precision and large tonnage of the archway, it is very typical in the current rolling mill installation. The present invention takes the installation of 4300 rolling mills as a test, which will be described in detail below in conjunction with the accompanying drawings.

[0086] See figure 1 According to the process flow chart of large rolling mill installation, the process steps of foundation preparation, mill backing plate installation, mill bottom plate alignment, spreader preparation, arch alignment, arch inspection, roll changing device installation and mill accessories installation are adopted.

[0087] Basic preparation: According to the construction characteristics of the project, set the rolling center line, the rolling mill transverse center line, the rolling mill reducer center line, and the roll changing device center line. Set a permanent cente...

Abstract

The invention relates to an installation of metallurgy industry rolling mills, pinch pass mill, burnishing machines and the like large-scale mechanical equipment, especially to an installation method of a large-scale rolling mill, which is characterized in that the installation of a large-scale rolling mill is realized by the process steps of base preparation, rolling mills bearing plate installation, rolling mills motherboard transverse alignment, sling preparation, memorial archway transverse alignment, memorial archway check-up, roll-changer installation and rolling mill accessory installation. The invention satisfies all requirement of different construction sites, effectively resolves hanging difficult problem, saves work efficiency about 6-7 times, ensures installation quality, uses hydraulic bolt stretchers to avoid bolt up force moment from macrolesion bolt, and adopts small fastening force moment to allow rolling mills subbase to become flexible. Work difference bands are used to control the roll changing transmission device central line and the rolling mill central line to ensure installation quality. According to combination of calculation and on-site practicality, the invention not only can be used for rolling mills installation, but also can spread in mechanical equipment installation with common advising signification.

Description

technical field [0001] The invention relates to a method suitable for the installation of similar large-scale mechanical equipment such as rolling mills, tempering mills, and skin-pass mills in the metallurgical industry, and particularly relates to an installation method of large-scale rolling mills. Background technique [0002] At present, in the rolling system of iron and steel enterprises, the rolling mill is the heart of the whole system, and its position is very important. With the development of science and technology, more and more new processes and technologies are applied to the rolling system. The process of rolling mill installation is very complicated, and the old installation method is not suitable for the installation requirements of the current new rolling mill. The old installation method is very difficult to ensure the quality of the installation and the construction period, which affects the service life of the equipment. In the prior art: (1) setting of...
