Check whether the straightening machine is operating normally, and check and remove all dirt, oil and metal chips on the machine. Then, adjust the brief analysis between the upper and lower rolls of the straightening machine.
In the straightening operation, it is required that the titanium alloy plate cannot have corners or crimping, otherwise, it must be flattened with a mallet; dirt and titanium chips are not allowed on the titanium alloy plate, otherwise, it must be cleaned and cleaned in time; the titanium alloy plate is straightened It must be aligned to the center, no skew, if any skew is found, it must be adjusted; the titanium alloy plate is not allowed to pass through the straightening machine, nor is it allowed to straighten two overlapping plates at the same time.
When the titanium alloy plate is straightened, when local waves are found, the pressure of the machine must be adjusted in time to eliminate the waves. For example, when there is a wave in the middle of the iron plate, the support roller in the middle should be raised (that is, u value is lowered). The larger the wave, the larger the rise, and so on.
When the titanium alloy plate is straightened, if the effective plate is stuck in the machine and is not allowed to pass by force, stop immediately, raise the roller, and then return to the titanium alloy plate. If you need to retreat the titanium alloy plate, you should also lift the roller to work.
It is not allowed to pressurize the work roll during the shutdown. At the same time, the straightened titanium alloy plate should be re-examined, and if there is any unqualified straightening, repeat the straightening. If straightening is really impossible, you should send it to a tension leveler for straightening.
