Three, structure composition The high vacuum heat treatment furnace is mainly composed of a vacuum furnace body, a heating furnace, a temperature measurement system, a vacuum system, a water cooling system, and a control system.
Four, equipment structure characteristics 1. Furnace The furnace body adopts a double-layer cylindrical vertical structure with water cooling between the inner and outer walls to ensure that the temperature of the furnace wall is below 55°C. The side of the furnace body is equipped with a vacuum pumping interface, a vacuum charging and discharging valve, etc. 2. Heating insulation system The heating system uses graphite soft and hard felt as the heat preservation material, graphite tube as the heating element, voltage transformation realizes low-voltage heating, reduces the arc effect, ensures the best temperature uniformity and uniform heating of the workpiece, and facilitates the maintenance and repair of the heating element. For replacement, the heating electrode is specially designed for vacuum sealing to ensure good sealing and insulation with the furnace body. 3. Vacuum system The vacuum system adopts a TK-200 oil diffusion pump, a 2X-30 rotary vane mechanical pump, a high vacuum butterfly valve, a vacuum gauge tube, a vacuum pressure gauge, a vacuum vent valve, a vacuum pipeline, etc., and an air charging interface is reserved. In order to reduce the vibration of the furnace body, a metal bellows is used for the connection between the vacuum pipeline and the pump, and the vacuum measurement is measured by a composite vacuum gauge. 4. Water cooling system The water cooling system is composed of chillers, water inlet pipes, return pipes, valves, pipelines, etc. Supply vacuum unit, furnace body, furnace door, etc. through pipelines. To ensure equipment safety. The spare water device of the equipment is provided by the customer, and the spare water flow is ≥10m3/h. 5. Control system The temperature is controlled by the digital display temperature program controller according to the process curve set by the user to automatically control the temperature, and has the PID self-tuning function, and the temperature can also be controlled manually according to the user's needs.
