Molybdenum high thermal conductivity can be rapidly cooled in air, it can not achieve the insulation problem aluminum rolling, so at the end we have to billet cooling TZM alloy plate is heated, the hot rolling. Its main role is shaping the grace and extension. Hot rolling process should consider the following two aspects:
1.Reduction of hot rolling.In the hot rolling process, it should be using a large amount of reduction and increase passes, which can increase productivity and continue to rolling deformation the inner and outer layers uniform. If you pass the processing rate is small, the deformation can not go deep into the middle of the slab, the slab serious distortion often caused by uneven rolling mouth and stratification.
2. The determination of the hot rolling finishing temperature.Studies have shown that, in the hot rolling stage, only to consider the size of the change TZM alloy plate, but also consider the slab finishing temperature. Finish rolling temperature (i.e. the temperature of the slab), the slab microstructure and properties have a great impact, thereby affecting the properties of the finished sheet. End rolling at high temperatures (above recrystallization of the slab), although the grain rolling slab deformation direction along a certain stretch processing, but very coarse grains, the individual crystalline regions prone isometric . Conversely stops rolling at a lower temperature, the slab having a thin flattened tissue along the longitudinal axis. Choice at a suitable temperature in a finish rolling slabs high temperature recovery state, this state of tissue, for subsequent warm rolling processing to provide a good foundation.
