What are the control systems for hot presses? Why is the hot plate deformed?

- Jul 17, 2018 -

In the hot press, its control system, mainly includes two parts, for the control of heating system and hydraulic system, but relatively speaking, its composition is relatively complex.

Therefore, if the function of hydraulic press is more complex, then should minimize the use of control elements, such as solenoid valve, to reduce its overall complexity. Hot Press in the course of use, its hot plate if deformation, then what is the reason?

The following small series to be specific analysis.

Hot Press plate deformation, the main reasons are:

(1) Heating temperature is uneven, preheating temperature rise too fast, thus making hot plate deformation.

(2) Steam heating, the steam pipe is not smooth, there is blockage, so that heat conduction problems, and thus make plate deformation. 

(3) The density of the slab is too low, so the pressure is too concentrated.
