Overall construction method of experimental rolling mill suitable for ultra-precise ultra-thin strip rolling process

Abstract

The invention provides an integral construction method of an experimental rolling mill suitable for an ultra-precise ultra-thin strip rolling process. The integral construction method comprises the following steps: prefabricating all modules required by the experimental rolling mill; assembling all modules in a manufacturing plant to form an experimental rolling mill; checking and testing the experimental rolling mills, selecting qualified experimental rolling mills and sending the qualified experimental rolling mills to a user site; wherein all the modules forming the experimental rolling mill at least comprise a rolling mill, a left process platform, a rolling mill base, a right process platform, a rolling mill shield, a main transmission device and rolling mill piping, the two process platforms are symmetrically arranged relative to the rolling mill and are both fixed to the rolling mill base, and the rolling mill base is installed on a civil foundation. A plurality of core parts of the experimental rolling mill are connected into a whole through the rolling mill base and then are connected with the civil engineering foundation, and the whole construction method not only provides enough high installation precision for rolling of the ultra-precise ultra-thin strip, but also greatly improves the construction efficiency.

Description

technical field [0001] The invention belongs to the field of strip rolling, and in particular relates to an overall construction method of an experimental rolling mill suitable for an ultra-precision ultra-thin strip rolling process. Background technique [0002] With the wide application of strips in the fields of national defense, military industry, home appliances and microelectronics, especially the promotion of high-tech electronic products such as curved screens, end users of products require strips with extremely thin thickness, high strength and excellent shape stringent requirements. At present, there is a huge domestic demand for such ultra-precision ultra-thin strips (high-precision, high-stability strips with a thickness less than 0.1mm), but most of the products are imported. The traditional rolling process and its equipment can be used in the production of low-end strips, but it cannot meet the requirements of the rolling process of ultra-precision ultra-thin ...

AI Technical Summary

Problems solved by technology

The traditional rolling process and its equipment can be used in the production of low-end strips, but it cannot meet the rolling process requirements of ultra-precision ultra-thin strips, and the following serious problems have been exposed in actual production and application:

[0003] (1) Low rigidity of equipment

[0004] While applying a huge rolling force to the processed strip, traditional rolling equipment produces huge deformation due to the influence of the strip reaction force, especially when processing extremely thin strips, the deformation of the equipment itself is even greater than that of the strip The thickness of the product itself, which will lead to excessive fluctuations in the thickness of the product or even unable to roll out a strip that meets the thickness requirements

[0005] (2) poor installation accuracy

[0006] The key components of traditional metallurgical equipment are rooted separately on the civil foundation, which results in different stand-alone opportunities of metallurgical equipment due to the uneven settlement of the civil foundation, resulting in poor installation accuracy, which cannot meet the rolling requirements of ultra-precision ultra-thin strips. Process requirements

[0007] (3) Low construction efficiency

[0008] The traditional metallurgical equipment construction method is that the equipment needs to be disassembled before leaving the manufacturing plant, and then the secondary assembly is carried out after entering the construction site. Due to the release of internal stress caused by repeated disassembly and assembly of metallurgical equipment, it is easy to cause poor equipment accuracy and greatly increased workload
