Problems solved by technology

However, the thinner the titanium strip, the worse the control accuracy of the plate shape, and there will be problems such as cracking, uneven deformation, surface damage, breakage, and serious edge waves, which will affect the normal use of the titanium strip.
At the same time, the energy consumption of the rolling mill will increase, and the loss of the roll will be serious

Abstract

The invention relates to a method for rolling an ultra-thin titanium belt. According to the technical scheme, the titanium belt to be rolled is placed into a rolling mill, rolling is carried out through six passes at a room temperature, and after rolling is finished, the thickness of the rolled titanium belt is 0.0085mm-0.0095mm. According to the technical scheme, the rolling mill is a 16 rolling mill, the titanium belt to be rolled is in an industrial grade, the titanium content is larger than or equal to 99.97wt%, the width of the titanium belt to be rolled is 145-155mm, and the thickness of the titanium belt to be rolled is 0.028-0.032mm. According to the method, the thickness of the titanium belt is even, the appearance of the titanium belt is neat, the rolling direction is smooth, cracking cannot occur, and edge waves and surface damages do not exist. The quality of the rolled titanium belt is high, the method has the advantages of reducing energy consumption, being simple in working procedure and improving efficiency, and labor intensity for follow-up machining can be reduced.

Description

technical field [0001] The invention belongs to the technical field of metal strip rolling. In particular, it relates to a rolling method of an ultra-thin titanium strip. Background technique [0002] Titanium has low density and high specific strength, not only has good corrosion resistance and strong damping resistance, but also is non-magnetic and non-toxic, so it has a wide range of uses. [0003] Due to the good corrosion resistance of titanium, the prepared titanium belt is widely used in seawater desalination, nuclear materials and other fields. Titanium strips are mainly used in the field of seawater desalination for welding of titanium tubes, titanium welded tubes and plate heat exchangers, etc. At the same time, they are also widely used in nuclear power plants along the coast. [0004] Titanium is non-magnetic and non-toxic. It is used in key parts of nuclear submarines and has a certain shielding effect on magnetic mines. Because its weight is much smaller tha...
