A nameplate should be installed in a prominent position outside the equipment, which includes the product name, model, factory number, date of manufacture, and manufacturing unit.

This vacuum heat treatment equipment is mainly divided into four parts: vacuum system, heating system, electronic control and cooling system.

This device is a high vacuum molybdenum gall heating distance front door opening device. The vacuum container is mainly made of high-quality S30408 stainless steel. In order to prevent burns to the human body caused by high temperatures, the container is made into two layers, with the middle layer used for water cooling. All pumping equipment is installed inside the instrument, and the vacuum and heating systems are operated on a tablet computer above the control cabinet. This system integrates vacuum heating into one, improving the integration and stability of the system. The operation is simple and convenient, and the system also has certain expandability and redundancy for subsequent functional expansion. The core of vacuum degree and temperature equipment control is the system.

Place the test piece into the vacuum chamber, then close the vacuum chamber door (heated to an internal molybdenum gall heating type), and work can begin. After the vacuum is drawn to the specified specifications of the process, it can be heated and the heating system inside the high vacuum can be turned on, which can cause the gas molecules on the inner wall of the device and the gas molecules on the inner wall of the high vacuum pipeline to desorb and be extracted through the vacuum system. After a certain period of time, when the vacuum level inside the device reaches the required vacuum level for the process, cathodic decomposition or heat treatment of the device can be carried out to complete the vacuum process flow.
