Stringent secrecy, so as to cause the monopolization of the poor slab supply of material.
Compared with TWB, TRB has following superiority：（1）Weight loss effect is more preferable；（2）Mechanical performance variation is continuous,
Adaptability is stronger, due to TRB along its length on hardness, mechanical performance variation than shallower, no tailor welded is shown
Hardness and stress wave crest；（3）Thickness distribution " can make to measure ", can and molding loaded according to the parts to be produced institute
Numerical simulation result adjusts and optimizes thickness distribution position and size, and the quality of parts is made to mitigate to the maximum extent；
（4）Subsequent forming process reliability higher.But the unequal thickness plate of rolling also has its limitation, the variable cross-section rolled first is thick
Degree can only occur in the initial rolling direction of plate and thickness also can only be in an a certain range；Secondly, the difference of rolling is thick
Plate can only realize the link of material, width plank of the same race of the same race；Finally, the costly and supply of the poor slab of rolling is limited
System.
