The methods of two-roll cold rolling tube have the following advantages:
(1) The pass working rate is large, and the maximum processing rate can reach more than 80%, especially suitable for the alloy tube processing of titanium alloy and cold working with low-performance;
(2)It can produce the pipes with large length, the longest can reach 30m;
(3) Omit or reduce the annealing of part alloys and intermediate annealing, the production efficiency is high, and the cycle is short;
(4)The high automation degree of equipments can reduce the labor intensity;
(5)The pass replacement is simple, and the adjustment of the dimensions is convenient and quick;
(6) It can produce the special pipes and variable cross section tube.
The methods of two-roll cold rolling tube have the following disadvantages;
(1) The structure of cold rolling pipe machine is complex, the precision of equipment requires very high, and the investment and repair cost a lot;
(2)The design and manufacturing of tools are very complex;
(3)The rolling pipe with large ellipticity, corrugated, edge etc., the outside diameter deviation of pipes is not easy to control. Therefore, the pipes after rolling can achieve the requirements of the finished pipes by the tensile reducing.
