Titanium plate rolling process
1, hot-rolled titanium plate
Titanium slab is based on the initial slab or forging slab as raw material "by the heating - rolling - hot straightening - heat treatment - interrupted - Orthopedic - descaling - pickling and other basic production processes, and then According to the requirements of the surface for processing, such as the need to polish with emery cloth with "the final plank finished.
2, hot-rolled titanium coil
Hot-rolled titanium coil is made of the same titanium slab as the slab. Since the oxygen diffusion layer generated during the heating of the titanium slab causes defects in the slab during cold-rolling, it has to be removed before cold rolling. Therefore, Quality considerations, the thickness of the diffusion layer as thin as possible.
To this end, hot-rolled titanium coil heating temperature should be set to ensure stable rolling and can be rolled into the case of the band as low as possible In recent years,
The technical progress of hot rolling titanium coil mainly discusses the most suitable heating conditions (temperature, time, air ratio, etc.) to reduce the oxygen diffusion layer; fixed parts (rails, etc.) transformation, to prevent the titanium band and fixed parts (Rails, etc.) of the scratch. In the future should be conducted as titanium hot rolling equipment for the transformation, to further inhibit the growth of oxygen diffusion layer, more effectively prevent scratches and improve the quality of the strip.
3 cold rolled titanium plate
Cold-rolled titanium plate is the point of hot rolled titanium coil (thickness of 3mm ~ 6mm, width of 600mm ~ 1600mm, single-roll quality in the following 10t) as raw material.
The overall production process is atmospheric annealing, phosphorus removal, surface defects removal, cold-rolling, cleaning, vacuum annealing, flat rolling, orthopedic, finishing (slitting, board cutting, etc.). Or atmospheric annealing phosphorus removal instead of cleaning vacuum annealing process.
In recent years, the technical progress of cold-rolled titanium plate mainly in four aspects;
Descaling; the cold rolling process; annealing process; smooth rolling and finishing technology.

The current cold rolled plate annealing methods are the following 3 ways: (1) vacuum annealing. (2) Atmospheric annealing. (3) continuous vacuum annealing atmosphere.
