When the conditions in the vacuum induction melting furnace change, the practice temperature may be contrary to the set value

Vacuum induction melting furnace product use: this equipment is the first for colleges and universities and scientific research units and so on under the condition of vacuum or protective atmosphere of metal materials, such as stainless steel, nickel base alloy, copper, alloy steel, nickel and cobalt alloys, rare earth neodymium iron 錋) smelting processing, can also be used for alloy steel vacuum briefing and fine casting processing. The equipment USES the temperature control surface control power heating, the temperature measurement using infrared instrument, the temperature is more accurate, more energy saving, vacuum induction furnace.

Advantages of vacuum induction furnace with temperature measurement:

The melting speed is fast, and the temperature can reach 2100℃. Optional heating and temperature control program. Set the heating or cooling curve according to your process requirements, and the equipment will take the initiative to heat or cool in accordance with this process. With a dumping device, the molten sample can be dumped into a pre-prepared ingot mold and poured into the desired sample shape. Can be smelted in a variety of atmosphere conditions: air conditions, protective atmosphere conditions and high vacuum conditions smelting, buy a device, end a variety of functions; Degree to save your capital. With secondary feeding system: other elements can be added in the melting process to facilitate the preparation of diversified samples. The furnace body is all stainless steel structure, and with water cooling, to ensure that the temperature of the shell is lower than 35℃, protect your person.

When the conditions in the vacuum induction melting furnace change, there may be a violation between the practice temperature and the set value. At this time, the violation quantity can be corrected through the self-setting function in the temperature control instrument, so that the temperature rise is carried out strictly in accordance with the set curve. The heating element is the load of the heating power supply, and its material is selected high temperature molybdenum belt, which can work in high temperature condition for a long time. The resistance value of the heating element should match the magnetic voltage regulator, otherwise the temperature rise will not go up or the magnetic temperature rise will be high. The main circuit of the heating power supply is the three-phase communication power supply, which is controlled by the communication contactor, and the control circuit is controlled by the temperature controller.

Control line planning Double-chamber vacuum furnace line planning as an input unit. In order to satisfy the control cabinet panel operation, active control signal detection and alarm, the input unit includes the starting of the incoming and outgoing materials, the movement of the workpiece car, the heat isolation switch, the operation of the vacuum unit, the air charging valve, the start and stop of the fan, the air release valve, the heating, the vacuum valve and operation selection and other knob switches, as well as the limit switches and alarm signals; The output unit includes heating communication contactor, vacuum unit, workpiece car, vacuum valve, isolation valve, charging and releasing valve, charging valve, partial pressure valve, releasing valve, indicator light and other performing elements as well as sound and light alarm. Manual operation is mainly used for debugging and protection of vacuum furnace. The control is input operation, and corresponding component action is performed. Each component is set as interlock to prevent misoperation. Active operation is applied to the normal operation of the vacuum furnace. It is an active control signal detected. After judgment, active control is carried out according to the application program.
