Embodiment Construction

[0027] S1: Foundation handover and acceptance, collecting and confirming that the foundation meets the installation conditions and acceptance data, according to the as-built drawings and technical data provided by the civil engineering unit, according to the drawings, the foundation dimensions, center line, elevation, verticality, levelness and expected Buried anchor bolts and reserved holes should be carefully retested;

[0028] S2: Before the installation of the rolling mill, it is necessary to conduct a preload test on the installation point of the rolling mill, set up settlement observation points and make detailed settlement observation records. The observation points are installed at four points evenly distributed around the installation point of the rolling mill. The observations should be timed and recorded in detail , the observation time is until the settlement of the installation point is basically stable, and the preload weight of the basic preload test is taken a...

Abstract

The invention discloses an installation method of a high-precision ultra-thin aluminum foil rolling unit. The installation method comprises the following steps that S1, foundation final acceptance iscarried out, acceptance data for confirming that a foundation has installation conditions is collected, when the foundation is accepted, according to completion drawings and technical data provided bycivil engineering units, the foundation outer shape dimension, the center line, the elevation, the perpendicularity, the levelness, pre-buried foundation bolts and reserved holes are carefully re-measured according to the drawings, and a pre-pressing test is carried out on an installing point of the rolling unit set before the rolling unit set is installed. High-precision measuring instruments such as a micrometer rod, a high-precision level gauge and a frame-type leveling instrument are adopted for measurement, so that the installation precision of the unit is guaranteed; and the reasonableinstallation sequence is selected, unit measurement and unit installation precision adjustment are facilitated, the form and position error between units is guaranteed, the unit installation precisionis improved, construction is safe, the construction period is short, the hoisting cost is low, the project passes acceptance check at a time, and the installation method has wide application prospects.

Description

technical field [0001] The invention relates to the technical field of installation of aluminum foil rolling mills, in particular to a high-precision ultra-thin aluminum foil rolling mill installation method. Background technique [0002] The aluminum foil rough rolling mill is a device that rolls the aluminum plate and coil with a raw material of less than 0.5mm through several passes to make it into aluminum foil with a thickness of more than 2×0.0045mm. Three conditions must be met in case of fire or explosion in aluminum foil rolling : Combustibles, such as rolling oil, cotton yarn, rubber hose, etc.; Combustibles, that is, oxygen in the air; Ignition sources and high temperatures, such as friction, electric sparks, static electricity, open flames, etc. Lack of one of these conditions will not burn, fire and explode. The oil vapor and oxygen in the air produced in high-speed aluminum foil rolling are unavoidable, so the key to safety and fire prevention in high-speed al...
