Embodiment

[0036] In order to clarify the rolling process of titanium coils, two specific processes are listed below.

[0037] 1. The rolling table of 4.0mm-1.0mm-0.3mm thick titanium coil is shown in Table 1 and 2:

[0038] Rolling table of 4mm thick titanium coils rolled on a twenty-high reversing cold rolling mill

[0039] Table 1: Rolling schedule of 4mm thick titanium coils rolled on a 20-high reversing cold rolling mill (first rolling pass)

[0040]

[0041] It can be known from the above table that the total reduction rate increases layer by layer, and the growth rates are 69.58%, 29.24%, 16.15%, 10.14%, 6.83%, and 4.31%, respectively. The unit front tension of the seven passes is 1.2, 1.26, 1.24, 1.18, 1.09, 1.06, 1.04 of the unit back tension. The total back tension of the seven passes is 1.09, 1.01, 1.01, 1.03, 1.08, 1.09, 1.08 of the total front tension.

[0042] The rolling oil flow used is 70-80% of the total rolling oil flow of the twenty-high cold rolling mill, and t...

Abstract

The invention provides a method for producing a metal titanium roll with the thickness not more than 0.3mm through a twenty-roller cold rolling unit. The method comprises two rolling processes. The first rolling process is that an annealing state titanium roll with the thickness ranging from 2mm to 4mm is rolled 5-10 times to achieve the target thickness, and the second rolling process is that a titanium roll with the thickness ranging from 0.7mm to 1.5mm is rolled 6-13 times to achieve the thickness not more than 0.3mm, wherein the pressing rate in the two rolling processes ranges from 8% to 25%, the pressing rate of one time of single rolling is 80-100% of the pressing rate of the previous single rolling, the rolling speed is kept between 50m / min and 120m / min, and the unit forward pull is 1-1.3 times that of the unit backward pull. An effective strip surface lubrication system and a model control system are established through an existing twenty-roller reversible type cold rolling unit, the rolling technology of an ultrathin titanium is optimized, the total deformation of each rolling process is controlled within 80%, and the requirement-conformed thin titanium coiled stock with the thickness not more than 0.3mm can be produced.

Description

technical field [0001] The invention relates to the technical field of producing titanium metal coils, in particular to a method for producing metal titanium coils of 0.3 mm or less by a 20-high cold rolling mill. Background technique [0002] Titanium, known as the "third metal", is an emerging metal with great national defense significance and significant economic benefits in the field of contemporary high-tech and new materials. As a structural material, it has a series of excellent properties such as light weight, high strength, corrosion resistance, heat resistance, non-magnetic and ultra-low temperature resistance; as a functional material, it has four major properties: shape memory, superconductivity, hydrogen storage and biocompatibility. Its unique performance is not only a key material for cutting-edge weapons of national defense, but also an important material necessary for the transformation and upgrading of traditional industries and technological progress. It i...
