Vacuum heat treatment temperature control system

Design of PLC temperature control system for vacuum heat treatment equipment

Vacuum heat treatment is a new type of heat treatment technology combining vacuum technology and quenching and treatment technology. The vacuum environment where the vacuum heat treatment is located refers to a natural environment with an atmosphere of less than one atmosphere, including low vacuum, medium level vacuum, high vacuum and ultra wide vacuum. The heat treatment also belongs to the manipulation and tempering treatment.

Temperature control has become a crucial stage in industrialized production and scientific research activities. Can the temperature control be successfully achieved within the required range and relate to the success and failure of all thematic activities? Because of the multiplicity and multiplicity of the other half, the multiplicity of the selected temperature control methods is caused.

In the temperature controller of the vacuum heat treatment equipment, the temperature of the main parameter to be measured must first be converted by the controller into the necessary data signal, and then compared with the preset value to compare the obtained error data signal. After having to perform regular calculations, a relative control value is obtained. At this time, the manipulation amount is donated to the automatic control system to carry out the relative manipulation, and the work is continuously carried out, thereby exceeding the purpose of automatic adjustment.
