- Product Introduction
Furnace body part of vacuum continuous furnace:
1. The furnace body is divided into three parts: the heating zone, the constant temperature zone and the cooling zone. The shell is made of steel profiles, steel plates, and fully sealed and welded sections.
2. Requirements for the furnace: the heating elements in the same temperature zone are evenly distributed up and down, and the furnace material is made of 75 corundum mullite, 80 corundum mullite, and 95 corundum products (no deformation and burnout under normal use conditions). The hearth adopts five-point wear-resistant corundum mullite rail structure. The furnace roof brick adopts a vault, and the furnace roof has a large space, so that the exhaust gas can be discharged smoothly.
3. The furnace is single channel and single push plate, the furnace structure is stable, the furnace temperature and atmosphere are uniform, energy saving and durable, and the structure design is reasonable.
4. The furnace lining refractory material is made of high-quality lightweight thermal insulation composite materials to reduce energy consumption and the temperature of the outer surface of the furnace.
5. In order to prevent the exhaust gas from corroding the heating rod, the heating rod is required to be protected by a 95 porcelain tube.
6. The wiring cavity of the high temperature resistance wire rod is sealed with silicon rubber, and the terminal column is made of ceramic insulating column.
Vacuum continuous furnace electrical part:
1. The electrical part can be divided into: electric control part and temperature control part. The entire power distribution is distributed through the air switch, and the capacity of the air switch is selected according to the power of each part; each temperature zone is controlled by an independent air switch.
2. The temperature control instrument adopts digital display intelligent instrument (Xiamen Yudian). The temperature control instrument is equipped with manual and automatic PID adjustment, which can automatically track and set the PID value, and has sound and light alarms such as temperature compensation, over temperature, and broken coupler. Function.
3. Temperature control method: using thyristor module phase-shift trigger, 0~98% power output can be adjusted. The temperature zone adopts 3-phase control. Xiamen Yudian three-phase trigger is adopted, which is reliable and stable.
4. Heating element: The heating element adopts high temperature resistance wire rod.
5. The panel of the control cabinet is equipped with the main power switch, voltmeter, ammeter, intelligent digital display temperature control instrument, switch, button, indicator light and other corresponding Chinese instruction signs.
