Key Technical Parameters
Heating system and final rolling temperature:
β-type titanium alloys: the heating temperature before rolling needs to be slightly lower than the (α+β)/β phase transition temperature to ensure that the rolling process is completed in the α+β phase region.
Titanium alloys of type α: the heating process is carried out in the α+β phase region.
α+β type titanium alloys: the heating temperature is higher than the β transition temperature to ensure that the material is sufficiently softened for rolling. The heating time is based on the thickness of the material, usually calculated at 1~1.5mm/min.
Rolling speed:
In view of the large output demand for titanium and titanium alloy rolled profiles and the length of the product needs to be maintained at a certain level, the rolling speed is generally controlled at 1~3m/s to avoid quality problems caused by excessive speed.
Roll hole design:
According to the titanium alloy's deformation resistance, wide spread value and elongation and other characteristics, select or design a suitable roll hole pattern. For mass production of titanium alloy profiles, the roll hole pattern can be specially designed for titanium alloy to optimize rolling efficiency and product quality.
Process optimization and future prospects
With the progress of science and technology and changes in market demand, titanium wire rolling process is also constantly optimized and innovative. In the future, it is foreseeable that further breakthroughs will be made in the following areas:
