Embodiment 1

[0016] The specifications of the annealed 1.53 × 1060mm titanium coils are sent to the conventional tempering machine of the prior art. The rolling speed is 100m / min, the uncoiling tension is 0.5 tons, the crimping tension is 3.0 tons, and the elongation is 0.8%. Under certain conditions, the ordinary leveling roller on the leveling machine directly stretches the titanium coil to ensure the mechanical properties of the leveled titanium plate.

Embodiment 2

[0018] The annealed titanium plate coil of 1.53 × 1060mm is sent to the conventional tempering machine of the prior art. The rolling speed is 200m / min, the uncoiling tension is 4.0 tons, the crimping tension is 5.0 tons, and the elongation is 2%. Under certain conditions, the ordinary leveling roller on the leveling machine directly stretches the titanium coil to ensure the mechanical properties of the leveled titanium plate.

Embodiment 3

[0020] The specifications of the annealed titanium coils of 1.53×1060mm are sent to the conventional tempering machine of the prior art. The rolling speed is 50m / min, the uncoiling tension is 2.0 tons, the crimping tension is 4.0 tons, and the elongation is 1.8%. Under certain conditions, the ordinary leveling roller on the leveling machine directly stretches the titanium coil to ensure the mechanical properties of the leveled titanium plate.

Abstract

The invention provides a method for levelling a titanium plate coil, which comprises the following steps: delivering the titanium plate coil subjected to annealing treatment to a levelling machine, and directly carrying out levelling extension on the titanium plate coil by a levelling roll on the levelling machine or carrying out wet levelling on the titanium plate coil by the levelling roll under the conditions that the rolling speed is 50 to 200 meters per minute, the uncoiling tension is 0.5 and 4 tons, the curling tension is between 3.0 and 5.0 tons, and the extension rate is between 0.80 and 2.0 percent. After the cold-rolled and annealed titanium plate coil is subjected to leveling extension by the levelling roll on the levelling machine, the levelling method can eliminate stress and influence of the stress, level plate surfaces, and obtain better surface quality; and all the plate shape, dimension, surface quality, mechanical property, and the like of the leveled titanium plate coil achieve national standard requirements, and completely meet market demand.

Description

technical field [0001] The invention relates to a flattening method for titanium coils, in particular to a flattening process for cold-rolled industrial pure titanium coils, and belongs to the technical field of metal material processing. Background technique [0002] Cold-rolled titanium plate is a new material with high strength, light weight, good surface quality, and strong acid and alkali corrosion resistance. But at the same time, cold-rolled titanium plate has the characteristics of low elastic modulus, high yield ratio, large deformation rebound, and high deformation strengthening rate. It is these characteristics that increase the difficulty of production of titanium plate. In addition, the cold-rolled titanium coils after annealing need to be smoothed to eliminate the influence of stress, level the flat surface, obtain better surface quality, and make the mechanical properties fully meet the requirements of national standards. However, when the titanium coil is pr...
